We also have epidemiologic studies, like the Physicians’ Health Study, the Baltimore Longitudinal Study of Aging, and the Massachusetts Male Aging Study, that include tens of thousands of men who are followed for 5, 10, 15, or even 20 years. At the end of the study period, the researchers see who developed prostate cancer and who didn’t. They can then look at blood samples taken at the start of the study to see if, for example, the group that got prostate cancer had a higher level of testosterone over all. About 500,000 men have been entered in some 20 trials of this type around the world. Not one of those studies has shown a definitive correlation between prostate cancer and total testosterone. Three or four have shown weak associations, but none of those have been confirmed in subsequent studies.
Although some men believe that taking testosterone medications may help them feel younger and more vigorous as they age, few rigorous studies have examined testosterone therapy in men who have healthy testosterone levels. And some small studies have revealed mixed results. For example, in one study healthy men who took testosterone medications increased muscle mass but didn't gain strength.
Hello there Abraham. My doc and you know each other well. We reside in Richmond, VA. Doc told me to inject my weekly Cypionate into sub fat for longer absorption, with reference you shared this info him with him. I have been his TRT patient for 10 years now. He is the best. I wont mention names. Please point me to a study showing the results of testosterone absorption from fat.
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]
Total levels of testosterone in the body are 264 to 916 ng/dL in men age 19 to 39 years,[169] while mean testosterone levels in adult men have been reported as 630 ng/dL.[170] Levels of testosterone in men decline with age.[169] In women, mean levels of total testosterone have been reported to be 32.6 ng/dL.[171][172] In women with hyperandrogenism, mean levels of total testosterone have been reported to be 62.1 ng/dL.[171][172]
On review of the patient’s history, he was found to have undergone laboratory tests before starting to use the aforementioned testosterone booster product. All blood parameters (testosterone hormone and full chemical profile) before product intake were in the normal range. A physical examination that included blood pressure and pulse assessments showed nothing out of the ordinary, and the man appeared to be in good condition before product consumption. After that medical checkup, the athlete began to consume the product for 42 continuous days divided into 2 cycles (each cycle comprised 24 days). The daily dose was a single pack of Universal Nutrition Animal Stak (ingredients are listed in Table 1), following the exact direction of the manufacturing company hoping to get the best results.
Glad to be heard. I have been using 10 times the recommended prescription dose of injectable test over the course of 6 years. Yes, 10 times the recommended dose. I use 250 at the lowest and 1000 mgs a week and sometimes 1200 mgs weekly. I am 50 years old. I look better than 90% of the 25 year olds I see in the gym. I have had zero issues. Acne a little , testicle shrinkage maybe 15%. No big deal. My sex drive is on fire. I bench pressed 340 pound today. I weigh 195 pounds and lean and muscles defined and hard as a rock. Doctors in the USA have no clue what they are doing. They read literature and have no experience or facts about test. They prescribe 50 mgs a week. Way short of what we as men need. Everyone is different, but 250mgs weekly is what we need typically. Injectable is the way to go. Gels are a weak joke. My doctor basically told me he was scared to prescribe more than 50 mgs weekly for fear of being sued if something went wrong. I found my own source and have been on top of the world for 6 years. Father died of prostate cancer. Mine prostate is fine. Prostate cancer from test is another example of ignorance in medical field. I am living proof that one can inject 10 times the recommended rate for the better part of a decade with no probs. I do hope the medical field catches up with the times and stops relying on archaic info.
The basis for my thinking that T levels could be boosted by cold baths came from a post I wrote a few years ago on the benefits of cold showers. One benefit I found in my research was that they could increase testosterone levels. I mentioned a 1993 study done by the Thrombosis Research Institute in England that found increased T levels after taking a cold shower. Here’s the thing. I can’t find a link to the original source and I can’t find any other studies that support this claim! So without supporting research, I’m unsure of the effects of cold showers on testosterone.
This is the best BCAA supplement ever created.  You see this is not your typical BCAA supplement that all the other supplement companies sell.  Those products are simply free-form amino acids made by some Chinese manufacturer and packaged in the United States.  Free form amino acid supplements have been around since the 1980’s and they have never been proven to be helpful in building muscle mass.  In fact after whey protein came out in the 90’s it really made BCAA amino acids obsolete because whey protein contains over 30% BCAA.  If you want more BCAA’s simply use another scoop of whey protein instead of BCAA powder.  Its cheaper, tastes better, and contains plenty of BCAA plus all the other amino acids.  Ok so now that I have convinced you that free form BCAA’s supplements are pretty much worthless let me tell you about our new Advanced BCAA’s.

A number of epidemiological studies have found that bone mineral density in the aging male population is positively associated with endogenous androgen levels (Murphy et al 1993; Ongphiphadhanakul et al 1995; Rucker et al 2004). Testosterone levels in young men have been shown to correlate with bone size, indicating a role in determination of peak bone mass and protection from future osteoporosis (Lorentzon et al 2005). Male hypogonadism has been shown to be a risk factor for hip fracture (Jackson et al 1992) and a recent study showed a high prevalence of hypogonadism in a group of male patients with average age 75 years presenting with minimal trauma fractures compared to stroke victims who acted as controls (Leifke et al 2005). Estrogen is a well known determinant of bone density in women and some investigators have found serum estrogen to be a strong determinant of male bone density (Khosla et al 1998; Khosla et al 2001). Serum estrogen was also found to correlate better than testosterone with peak bone mass (Khosla et al 2001) but this is in contradiction of a more recent study showing a negative correlation of estrogen with peak bone size (Lorentzon et al 2005). Men with aromatase deficiency (Carani et al 1997) or defunctioning estrogen receptor mutations (Smith et al 1994) have been found to have abnormally low bone density despite normal or high testosterone levels which further emphasizes the important influence of estrogen on male bone density.

High levels of testosterone in the bloodstream lead to increased energy and aggressiveness. The latter pertains to one’s sense of motivation to train harder to achieve optimum muscle growth. Increased aggressiveness or motivation during a workout due to the intake of testosterone boosters guarantees faster progress to beginners as well as professional athletes and bodybuilders.
Every vitamin, mineral, and ingredient that affects the human body can be taken in enough quantities that they are harmful, or toxic, even the ones that — at lower levels — are beneficial or necessary. Unfortunately, testosterone boosters contain a lot of ingredients that are not well understood. This means in addition to not being able to confirm whether certain ingredients increase testosterone, the scientific and medical communities also don’t know at what levels many ingredients become toxic. On the up side, you might need to eat several pounds of a particular leafy plant before it becomes harmful. On the down side, it could be significantly less that pushes you over your body’s limit. We simply don’t know how little or how much the human body can tolerate. We recommend keeping your doctor in the loop when you add any supplement with unproven ingredients into your diet — they’ll be able to help you find and track any undesired side-effects that these ingredients might cause.
The unsexy truth is that increasing T naturally simply comes down to making some long-term changes in your diet and lifestyle. As you’ll see, what I did to increase T largely boils down to eating better, exercising smarter, and getting more sleep. That’s pretty much it. But as with most things in life, the devil is in the details, so I’ll share with you exactly what I did and provide research that explains why the things I did helped boost my testosterone.

Testosterone is a sex hormone that plays important roles in the body. In men, it’s thought to regulate sex drive (libido), bone mass, fat distribution, muscle mass and strength, and the production of red blood cells and sperm. A small amount of circulating testosterone is converted to estradiol, a form of estrogen. As men age, they often make less testosterone, and so they produce less estradiol as well. Thus, changes often attributed to testosterone deficiency might be partly or entirely due to the accompanying decline in estradiol.
I am 41, T was tested at 400 last month. I was Very active /hyper growing up. I have felt my strength and energy fade over the last 10 years to the point that i now take a nap in the afternoon. Sexual performance has been on a steep decline since 35 to the point of disfunction with out herbal pills or cialis. Also had 2 kids in last 5 years,(second marriage) , and at times have a hard time tolerating the stresses due to lack of energy to cope with the increased emotional load.

I have been searching quite a while for a testosterone booster that could help me in a few different ways yet not to be too expensive. Over the years, I have experienced a low irritability tolerance(meaning it doesn’t take much to send me “over the top”) and have moods swings due to negative situations. I would like to be more at peace with myself & around others(without trying to fake it).I don’t usually have a lot of energy at work & rely on energy drinks. I also have a lower sex drive due to what I believe is low blood flow. I am 43 years old and am not over weight, but could stand to tone up and lose a little around the waist. If this site is legit, I would like to know your opinion on what I have disclosed & what you recommend.
Studies also show a consistent negative correlation of testosterone with blood pressure (Barrett-Connor and Khaw 1988; Khaw and Barrett-Connor 1988; Svartberg, von Muhlen, Schirmer et al 2004). Data specific to the ageing male population suggests that this relationship is particularly powerful for systolic hypertension (Fogari et al 2005). Interventional trials have not found a significant effect of testosterone replacement on blood pressure (Kapoor et al 2006).
"Boy, I'm doing fine, you can't imagine! I play basketball 6 days a week all winter. I'm 63 years old. I play with 19-year-olds, and I hold my own every day. And Andro400 helps a lot. I'm quick as a cat -- it's amazing! I absolutely know the difference. I'm having a blast, and I appreciate your product. It works wonderfully! You can’t imagine what I can do at my age -- and you help. That ain't no kiddin!"
Andy – If you take testosterone, your hypothalamus will notice an abundance of testosterone in your system and will instruct your pituitary gland not to send LH and FSH to your testicles. If you’re testicles are not receiving these two hormones, they will stop making testosterone. If you quit testosterone call turkey, you will likely fall back to your baseline level fairly quickly. There is a protocol however to get back to your normal production much quicker should you choose to quit therapy.
Vitamin D3 has the ability to naturally boost testosterone levels.  Increasing serum vitamin D levels in the body can help increase testosterone production, allowing you to potentially build muscle at a faster rate. If you don’t live in an area of the world that allows for a good amount of sunlight, you could become deficient and could benefit from a vitamin D supplement.
Alcohol has constantly been shown to lower testosterone levels. It’s even worse if you’re a heavy beer drinker. Wanna know why? Because beer raises your estrogen levels due to the phytoestrogens that are produced from the hops used to make beer. If that’s not enough, studies have shown that alcoholics have lower levels of testosterone than non-alcoholics.
Natural testosterone boosters also help to increase the amount of free testosterone in the body. There are a couple of different ingredients they use that help with this. One of these ingredients is stinging nettle. Stinging nettle is actually able to bind to the globulin in place of testosterone, therefore leaving more free testosterone in the body that is unbound.
Some of these signs and symptoms can be caused by various underlying factors, including medication side effects, obstructive sleep apnea, thyroid problems, diabetes and depression. It's also possible that these conditions may be the cause of low testosterone levels, and treatment of these problems may cause testosterone levels to rise. A blood test is the only way to diagnose a low testosterone level.
