Low testosterone levels can cause mood disturbances, increased body fat, loss of muscle tone, inadequate erections and poor sexual performance, osteoporosis, difficulty with concentration, memory loss and sleep difficulties. Current research suggests that this effect occurs in only a minority (about 2%) of ageing men. However, there is a lot of research currently in progress to find out more about the effects of testosterone in older men and also whether the use of testosterone replacement therapy would have any benefits.
But can testosterone replacement therapy help with heart disease? Study results are mixed. Small studies in the early 2000s found that men with heart disease who underwent testosterone therapy saw only slight improvements. Some were able to increase their walking distance by 33 percent. Another study found that hormone therapy only widened healthy arteries but had no effect on angina pain.
“I did a lot of research on Andro400 before I ordered it because I've tried other products in the past and they haven't worked. But with this I could not believe the difference within, literally within a month. I'm 62 years old and since I started taking it I have lost 37 lbs. And I have more energy than I've had in 20 years. It's still coming off, but it's coming off slower now. It was the belly fat. I could get weight off but I could never get the tummy off, and now the tummy's coming off. Libido -- everything's better all the way around.“
Testosterone is well known as the most critical anabolic, not to mention androgenic, hormone in the body. It’s what separates the men from the boys. Healthy testosterone levels are critical for guys who want to build muscle mass, boost strength, and drop body fat. Testosterone also supports sexual health and gives a competitive edge. It’s truly the alpha hormone.
Caffeine: While caffeine can’t ramp up testosterone directly, it can help you put in the quality work in the gym that will spike your T. One International Journal of Sports Nutrition and Exercise Metabolism study, for instance, found that athletes who consumed caffeine before training lifted more—and experienced a greater subsequent lift in testosterone—than those who took a placebo.
Before taking any supplements, at either end of the spectrum, you need to check whether it’s low testosterone that is actually causing the problem. Taking something that you don’t need could potentially cause irreversible issues. For that reason, steroid hormones like DHEA should never be prescribed without having blood tests first. Roked also recommends regular blood monitoring to make sure you’re taking the correct dosage.
Aromatase inhibitors can boost testosterone on their own, but they can also complement other testosterone boosters. If you take a supplement that increases testosterone without inhibiting the aromatase enzyme (through hypothalamic stimulation, for instance), you may find yourself with more estradiol than you need, a situation that taking an aromatase inhibitor may remedy.
The evidence shows that testosterone treatment does not change the strength or rate of urine flow, does not change the ability to empty the bladder, and does not change other symptoms such as frequency or urgency of urination, as assessed by the American Urological Association Symptom Score or the International Prostate Symptom Score. I’ve had a couple of patients over the years who had some worsening of urinary symptoms with testosterone, but that’s rare, even with long-term use.
Testosterone may fight depression. If you’ve been battling the black dog of depression, it may be because of low testosterone levels. Researchers have found that men suffering from depression typically have deficient testosterone levels. While scientists haven’t been able to figure out whether it’s low testosterone that causes depression or if depression causes low T levels, preliminary research has shown that some men suffering depression report improvement in mood and other factors of depression after undergoing doctor-directed testosterone treatments.
Ashwagandha is shown to be effective at reducing cortisol which in turn helps with testosterone production. There are also numerous studies showing the effects on improving testosterone in infertile men (ref 80).  If you are using the Aggressive Strength product you don't need to supplement with ashwagandha as it's included in the test booster formula. Likewise if you're using Tian Chi (my daily herb drink).
Zinc is an essential mineral that plays an important role in improving testosterone levels as well as sperm production. Oysters are rich sources of this mineral. An increase in testosterone levels also helps improve your sexual desire and energy, which means that you are going to derive more pleasure from your sexual encounters besides having higher chances of conceiving.

Another study in 2015 by Melville and friends gave subjects either three or six grams of DAA per day for a 14 days (2 weeks). Researchers noted that the 3g dose of D-aspartic acid did not result in any meaningful changes in testosterone levels (or any other anabolic hormones for that matter).[3] However, the group of men receiving 6g per day experienced a significant reduction in both total testosterone and free testosterone levels, with no concurrent change in other hormones tested.[3]


Men who start using the gels have to come back in to have their testosterone levels measured again to make sure they’re absorbing the right amount. Our target is the mid to upper range of normal, which usually means around 500 to 600 ng/dl. The concentration of testosterone in the blood actually goes up quite quickly, within a few doses. I usually measure it after two weeks, though symptoms may not change for a month or two.

Zinc deficiency also negatively affects testosterone levels, according a 2014 article in the Journal of Plant Biochemistry and Physiology. The authors of this review note that zinc supplementation can increase circulating testosterone in some populations. In fact, daily supplementation with typical doses may double testosterone within a few months.


I’ve had low testo in the winter for the last 10 years, with the lowest values around april (live in the north). But last year (in september) I started using vitamine D (10 000 IU) and K2 (180 mcg), combined with magnesium (200 mg malate) and zinc (25 mg malate and piccolinate) every night, and since then I no longer have low testo in the winter, and is feeling like I do in the summer and have normal testo levels. This combo may work for other people as well. And the risk for dangerous side effects is probabaly neglectable. But it takes a couple of weeks before it kicks in.
By passing this bill, the Congress has amended the Controlled Substances Act to include Androstenedione supplements such as 4 Androstenediol, 5 Androstenediol, etc. The original Anabolic Steroid Control Act was passed in 1990 creating a list of anabolic steroids that would be classified as "Schedule III" substances and put in the same category as drugs such as heroin and cocaine. Now, with the passage of Senate Bill 2195 (the Anabolic Steroid Control Act of 2004), they have added Androstenedione supplements to the Controlled Substances Act.
When testosterone and endorphins in ejaculated semen meet the cervical wall after sexual intercourse, females receive a spike in testosterone, endorphin, and oxytocin levels, and males after orgasm during copulation experience an increase in endorphins and a marked increase in oxytocin levels. This adds to the hospitable physiological environment in the female internal reproductive tract for conceiving, and later for nurturing the conceptus in the pre-embryonic stages, and stimulates feelings of love, desire, and paternal care in the male (this is the only time male oxytocin levels rival a female's).[citation needed]
Testosterone [Figure 1] is the main male sex hormone. It is responsible for male sexuality and is the main hormone-producing the features associated with masculinity such as substantial muscle mass, facial hair, libido, and sperm production.[1] Besides, the hormone has other vital functions as the basic chemical composition of testosterone is steroidal; and steroids are known to have significant physiological, as well as psychological, effects in male individuals, especially adults.[1] Testosterone production is reduced gradually in men starting from the age of 30.[2] Hence, testosterone blood concentrations slowly diminish as age progresses. As a result, men may experience a number of physiological and psychological events, such as a lack of sex-drive, erectile dysfunction, acute depression, fatigue, low energy levels, and insomnia.[3]
‘Testosterone boosting’ products  - found online, or in health food or body-building shops, these products claim to boost testosterone levels if you buy them. The majority of these products will not have the effect you want and are not worth spending money on. Any of these products that do have a real effect may have a form of prescription medication in which is both dangerous and illegal.
Looking purely at the biochemical numbers, The Endocrine Society* considers low testosterone to be a total testosterone level of less than 300 ng/dl, and I think that’s a reasonable guide. But no one quite agrees on a number. It’s not like diabetes, where if your fasting glucose is above a certain level, they’ll say, “Okay, you’ve got it.” With testosterone, that break point is not quite as clear.
Testosterone may increase competitiveness. Men are known to be a competitive bunch and testosterone is likely responsible for our drive to win. Testosterone is linked with a man’s desire for power and status (Dabbs & Dabbs 2000). Testosterone ramps up before a fight or competition – producing effects on muscle mass and hemoglobin, quickening reactions, improving visual acuity, and increasing your feelings of endurance and indomitability. It also increases your “gameness:” One study showed that a man’s testosterone level after losing a game predicted whether or not he got back in for another round. Men who experienced a severe drop were less likely to play again, while men who experienced little or no drop in T levels got back into the game. Researchers concluded from this observation that T is one of the factors driving competitiveness in men.
Ginger is considered a safe herbal medicine with only few and insignificant adverse/side effects [1]. Some minor adverse effects such as mild diarrhea have been associated with the use of ginger in humans [19]. Ginger may also cause heartburn and at much higher doses act as a gastric irritant [19]. One study carried out on male diabetic rats concluded that extracts of Zingiber officinale have high safety and intake of Zingiber officinale roots as a drink may be useful for diabetic patients who suffer from sexual impotency [20].
I started with the shots. Wowee! the effect was like night and day. For two years I was like a teenager. But then I noticed some REALLY risky (Health) behavior ( and memory gaps) and bad decisions with long-term implications(i.e judgement). So I tried stopping TRT (four years on the pumps),within four months, mood swings like menopause: snarly with co workers (not good in nursing), grumpy with everyone, switch from jovial to downcast in an instant (I’m male). Had to go back on and do an 18 mth taper, coupled with exercise. No TRT, makes exercise SO hard to do. Muscles seem so much more aware of stiffness.
I’ve been reading all these comments and replies here. This was a great article and if it does anything, it should stimulate you to talk to your physician. Your Dr. can take blood and have it annylized, then prescribe the proper direction to take. A lot of people here have been giving free advice, but who knows your system best? Am I going to take advice from someone who doesn’t know anything other than the symptoms I present? I’m not, but what if I’m allergic?
Cross-sectional studies conducted at the time of diagnosis of BPH have failed to show consistent differences in testosterone levels between patients and controls. A prospective study also failed to demonstrate a correlation between testosterone and the development of BPH (Gann et al 1995). Clinical trials have shown that testosterone treatment of hypogonadal men does cause growth of the prostate, but only to the size seen in normal men, and also causes a small increase in prostate specific antigen (PSA) within the normal range (Rhoden and Morgentaler 2005). Despite growth of the prostate a number of studies have failed to detect any adverse effects on symptoms of urinary obstruction or physiological measurements such as flow rates and residual volumes (Snyder et al 1999; Kenny et al 2000, 2001). Despite the lack of evidence linking symptoms of BPH to testosterone treatment, it remains important to monitor for any new or deteriorating problems when commencing patients on testosterone treatment, as the small growth of prostate tissue may adversely affect a certain subset of individuals.

Many endocrinologists are sounding the alarm about the damaging effects that come with exposure to common household chemicals. Called “endocrine disruptors,” these chemicals interfere with our body’s hormone system and cause problems like weight gain and learning disabilities. One type of endocrine disruptor is particularly bad news for our testosterone levels.
“She” being the key word. I had to quit a female doc because even though my level was down to 200, she thought I just needed more vitamin D! When I tried that and came back a few weeks later and told her there was no change in how I felt she refused to order another blood test, and after that wouldn’t even see me. I would never trust a female doctor with testosterone replacement therapy, as they all seem to have the same shit attitude from what my friends have told me, they treat it like it’s not a real thing even though you better bow down and kiss their asses when it comes to breast cancer and menopause.

Hi Dean, thanks for reaching out bro! While testosterone boosters will help increase your T levels, strength, and libido, you need to make sure you’re eating the right foods and exercising in the right way. What is your current diet and workout plan? Maybe we can help? If you’re serious about getting in shape, a quality testosterone booster can certainly help. If you have a look at our top testosterone booster page, you’ll see TestoFuel is our best choice. If you have any more questions, don’t hesitate to write back! All the best bro, don’t give up, you can do it!
The testosterone booster pills are effective from 4 to 8 hours. To maintain testosterone levels high during the whole day, you need a multiple daily dosing regimen. 2-times daily dosing still not always can improve hormone production to the greatest extent. 3-4-times daily dosing is the best solution to make your body normalize testosterone synthesis and prevent it from decreasing before you take another pill. Don’t forget that the regularity of daily supplement intake is crucial if you really aspire to give a boost to hormone production.
Testosterone is responsible for increased muscle mass. Leaner body mass helps control weight and increases energy. For men with low testosterone, studies that treatment can decrease fat mass and increase muscle size and strength. Some men reported a change in lean body mass but no increase in strength. It’s likely you’ll see the most benefits when you combine testosterone therapy with strength training and exercise.
The steroid hormone known as dehydroepiandrosterone, DHEA, plays an important role in sexual behavior, mental health and muscle growth. Your body uses this hormone to make sex steroids. Thus, taking a DHEA supplement should increase your circulating testosterone. A 2018 paper in the International Journal of Sports Medicine explored this possibility in athletic women.
Testosterone is the primary male sex hormone and an anabolic steroid. In male humans, testosterone plays a key role in the development of male reproductive tissues such as testes and prostate, as well as promoting secondary sexual characteristics such as increased muscle and bone mass, and the growth of body hair.[2] In addition, testosterone is involved in health and well-being,[3] and the prevention of osteoporosis.[4] Insufficient levels of testosterone in men may lead to abnormalities including frailty and bone loss.
The study population in these TTrials included men aged 65 years or older with mean morning serum testosterone concentrations of 275 ng/dL or less and symptoms of impaired sexual function, physical function, or vitality. These trials were placebo-controlled and the testosterone treatment group received 1% testosterone gel at variable doses adjusted to maintain plasma testosterone at levels normal for young men (500-800 ng/dL).

During the second trimester, androgen level is associated with sex formation.[13] This period affects the femininization or masculinization of the fetus and can be a better predictor of feminine or masculine behaviours such as sex typed behaviour than an adult's own levels. A mother's testosterone level during pregnancy is correlated with her daughter's sex-typical behavior as an adult, and the correlation is even stronger than with the daughter's own adult testosterone level.[14]
A study in the European Journal of Clinical Nutrition that showed drops in cholesterol levels also highlighted the benefits of Fenugreek in controlling glucose levels (this is in fact what the trial was intended to test). When you eat, your glucose levels spike. Fenugreek helps stimulate insulin release to slow down the absorption of sugars in your intestinal tract. Fenugreek might help control blood sugar levels in diabetics.  Furthermore, high glucose levels create a poor environment for testosterone production.  This is why Tim Ferris, in his testosterone diet, advises against consuming sweets and simple starches when you are trying to increase T levels.
Testosterone is an anabolic steroid hormone that plays a critical role in metabolism, sex drive, muscle building, mood regulation, memory & cognitive function.  Normal testosterone levels play a huge role in maintaining optimal weight as well as reducing risk of degenerative diseases such as osteoporosis, heart disease, diabetes, & certain cancers (1, 2, 3).

Testosterone is an androgen hormone produced by the adrenal cortex, the testes (in men), and the ovaries (in women). It is often considered the primary male sex hormone. Testosterone stimulates the development of male secondary sex characteristics (like body hair and muscle growth) and is essential in the production of sperm. In women, testosterone plays a role in egg development and ovulation.

Another effect that can limit treatment is polycythemia, which occurs due to various stimulatory effects of testosterone on erythropoiesis (Zitzmann and Nieschlag 2004). Polycythemia is known to produce increased rates of cerebral ischemia and there have been reports of stroke during testosterone induced polycythaemia (Krauss et al 1991). It is necessary to monitor hematocrit during testosterone treatment, and hematocrit greater than 50% should prompt either a reduction of dose if testosterone levels are high or high-normal, or cessation of treatment if levels are low-normal. On the other hand, late onset hypogonadism frequently results in anemia which will then normalize during physiological testosterone replacement.


I have been on TRT for over 8 years now. I feel GREAT! I read all these studies, hear in the news, and see all these dumb lawsuit commercials about testosterone causing cardiovascular events, blood clots and many other things. If anyone takes the time to do the due diligence and read the studies the picture becomes very clear. Unless you monitor all the other hormones, specifically, Estradiol, DHT, Pregenolone, Total Testosterone, Free Direct Testosterone, and DHEAS you are playing a deadly game. The reason is you must give something to control the pathways of T conversion into estradiol and or DHT. The vast majority of the studies used nothing to control those pathways and they gave men way, way more T than they needed to start with. They also gave forms of T that are not acceptable. Especially the oral version.
The largest amounts of testosterone (>95%) are produced by the testes in men,[2] while the adrenal glands account for most of the remainder. Testosterone is also synthesized in far smaller total quantities in women by the adrenal glands, thecal cells of the ovaries, and, during pregnancy, by the placenta.[130] In the testes, testosterone is produced by the Leydig cells.[131] The male generative glands also contain Sertoli cells, which require testosterone for spermatogenesis. Like most hormones, testosterone is supplied to target tissues in the blood where much of it is transported bound to a specific plasma protein, sex hormone-binding globulin (SHBG).
Now, many men bypass the natty test booster category altogether, head straight for designer anabolic steroids, and start injecting testosterone (among other things). And, while exogenous testosterone administration will always trump the effects of natural testosterone boosters, that instant gratification does not come without a long, dreadful list of unwanted consequences.

Overseas right now, and have an appointment in a few days to get all my levels checked. BTW, I want to just throw this out there. There are a number of companies that are selling “legal pro-hormones” or “test boosters”. I used several types. They were banned several times, and re-introduced, and ultimately have no real FDA oversight. Specifically LG Sciences, and a couple of others I tried. They do work, you will see gains, and quickly. You will gain a lot of water weight. You will get angry. You will eventually damage your liver no matter what their advertising tells you. I had a general physical, and my doctor thought I was an alcoholic…when I do not drink, he was shocked. I’ve flushed it all down the toilet, and the doc said to trim down the powdered supplements as well, as they can be very harmful. So….please heed my warning, that stuff will hurt you.

I highly recommend using a great essential amino acid mix post-exercise in order to boost testosterone.  These essential amino acids and especially the concentrated branched chain amino acids leucine, isoleucine and valine stimulate muscle protein synthesis.  Getting these amino acids in the post-workout window dramatically boosts testosterone production (14).  I like using our Amino Strong and will often recommend a scoop pre-workout and post-workout for the best muscle building, testosterone boosting benefits.

However, testosterone is only one of many factors that aid in adequate erections. Research is inconclusive regarding the role of testosterone replacement in the treatment of erectile dysfunction. In a review of studies that looked at the benefit of testosterone in men with erection difficulties, showed no improvement with testosterone treatment. Many times, other health problems play a role in erectile difficulties. These can include:
Vitamin D and zinc are both essential to testosterone production. A year-long study looked at the vitamin D and testosterone levels of 2299 men. It found that men with vitamin D levels above 30 nmol/L had more testosterone and lower levels of sex hormone-binding globulin (SHBG). SHBG binds to hormones so your cells can’t use them, and if you have too much of it, your testosterone levels drop [8]. Men with vitamin D deficiency had lower testosterone and higher SHBG levels.

Around age 30, men’s testosterone levels begin a long, gradual decline. (According to the FDA, normal T range is between 300 to 1,000 nanograms per deciliter (ng/dl) of blood serum. Anything below 300 ng/dl is considered low.) If a blood test confirms you have low T, your doctor may recommend a prescription testosterone supplement or replacement therapy.
This is over simplified but should offer you some clarity to what you are experiencing – If you are getting Testosterone Cypionate injections every 2 weeks, then you are on the roller coaster. I have great results with weekly injections and some folks need bi-weekly injections. It’s all how your body reacts but every 2 weeks is just plain too far apart as the product is relatively ineffective after 10 days. Measurable at 10 days? Somewhat but still ineffective at that point.
Testosterone may help you woo a woman. In the animal kingdom, higher testosterone levels have long been shown to be associated with a male’s dominance in the competition for mates. But a recent study has shown this is true for human males as well. When a pair of men were instructed to compete for the affection of an attractive female undergraduate, the men’s assertiveness, ability to control the conversation, and ultimately, their chances of having the woman say she “clicked” with them most, were positively associated with their pre-competition testosterone levels. So there is truth to the idea that men with swagger get the girl, and this self-assuredness may be partly rooted in T.

Testosterone is the primary sex hormone in men, and it is responsible for the development of many of the physical characteristics that are considered typically male. Women also produce the hormone in much smaller amounts. Testosterone, part of a hormone class known as androgens, is produced by the testicles after stimulation by the pituitary gland, which is located near the base of the brain, and it sends signals to a male's testicles (or to a woman's ovaries) that spark feelings of sexual desire.
