A: If a health insurance company is providing coverage for a medication, including testosterone replacement therapy, they determine the final cost of the product. Costs will vary from one health insurance plan to another. To determine the costs of the testosterone replacement options, the health insurance plan should be contacted. There are various options for testosterone replacement therapy including gels, injections, patches, and tablets that dissolve under the lip. All of the formulations can be effective and each has advantages and disadvantages. The most appropriate testosterone replacement therapy depends on a variety of factors, including cost, patient preference, and tolerability. Testosterone replacement gels, such as AndroGel and Testim, are very effective and easy to administer. AndroGel and Testim can be easily applied to the skin once daily. However, the gels can be irritating to the skin and AndroGel and Testim are typically quite expensive. Testosterone replacement injections, such as Depo-Testosterone (testosterone cypionate) and Delatestryl (testosterone enanthate), are usually inexpensive. The injections are given only once every one to two weeks. The major disadvantage with injectable testosterone is that testosterone levels may be difficult to control. Levels may be too high after an injection and too low before the following injection. A testosterone replacement patch, such as Androderm, is applied every night and left on for 24 hours. Androderm can be applied to the arm, back or stomach, in an area without too much hair. Androderm can cause irritation of the skin. A testosterone tablet, Striant, is placed under the upper lip against the gums and replaced every 12 hours. Striant molds to the upper gum so that eating and drinking can occur normally. The testosterone tablet can irritate the gums and cause a bitter taste and toothache. People with low testosterone should work with their doctor or healthcare provider to find a safe, effective, and affordable testosterone replacement option for them. For more specific information, consult with your doctor or pharmacist for guidance based on your health status and current medications, particularly before taking any action. Derek Dore, PharmD

Made many mistakes growing up. Late highschool, small group of guys tried Testosterone and obviously it worked great on all levels especially on the football field etc. College years we did it again and again but not anywhere near the levels of body builders we knew and saw at the gym. When it became harder to find, then….. poof it became “legal” in the form of Pro-hormones. Great right? Not so. It worked but it also worked on everything else in a negative way. Mainly liver toxicity that I noticed and just the general idea of not really knowing what was in it. When I was 38 I had a bad event with diverticulitis. I was hospitalized for 4 days and it was horrible. This is in an infection in a diverticula that forms in your intestines. It was so bad and fast that it spread with a rapid onset of epididymitis ( infection on the epididymis of your testical). After the hospital I went see my gastro who was a board member of a large anti aging group of doctors. We did bloodwork and My testosterone levels were lower than a woman! Like 110. He also explained to me that I had probably never fully recovered normal test levels from my last “get in shape” run with pro hormones 2 years before and it probably played a part in the weakening of my intestinal wall and immune system and after discussion I realized that I had exhibited all of the text book effects of low T to the letter. After spilling my guts to my doctor we decided upon the gel. It worked great but having kids around I was worried about it affecting them so we switched to in ejections taken every 2 weeks of cypionate 200mg and my wife helps me with that at home and I never stray from the regime . My levels are around 700 to 750 and basically PSA that is non existent. I am now 41 and feel great , go to Doctor twice a year for bloodwork and all is well. My doctor also tells me that in his opinion our environmental factors play a huge role in this, meaning hormones in meats, milks, public water etc. and because of that together with “Poor decision making (me in highschool, college etc) America is in the midst of an epidemic that is being under advertised and overlooked. I constantly read up on the latest info I can find and I liked reading this and your posts. Sometimes I feel guilty because I get comments on how I look and my energy levels and I wonder is this too good to be true? But if I am following a strict regiment and bloodwork reports good things…. Do I need to worry about anything else??? This is my story and I have never shared it with ANYONE other than my wife. Big move for me!! Last point……. This is a generalization but…….all women take hormones. It’s is universally accepted and part of a woman’s life without a doubt. Why is it Taboo to publicly discuss men and hormones? I guarantee if you are a man 35 and above and you did dumb things like me and or exhibit symptoms of low T, do yourself a huge favor and go see a doctor and get blood work done. More than likely you have it! I still hide all of this and I don’t want to shout it out because I feel embarrassed. WHY? Enough already!!!!
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.

If you're completely inactive, or if you're completely burned out from overly intense training, neither one is going to help your T-levels. And when it comes to nutrition, eating enough—and getting adequate dietary fats—are both essential for healthy testosterone levels, and for general health.[2] In "All About Testosterone," Chris Lockwood, Ph.D., notes that extreme low-calorie dieting and fasting will hinder testosterone levels from staying at their peak, along with better-known villains like chronic stress.
For this reason I recommend doing your own research on this supplement before taking it. 5g of ground up dried powder is what was used in the studies. I recommend taking 1-2 capsules of the concentrated form from Paradise Herbs. Alternatively, the Aggressive Strength Test Booster also has MP in its formula so you may prefer to use that blend instead. 
Topical testosterone, specifically gels, creams and liquids, may transfer to others. Women and children are most at risk of harmful effects from contact with them. You should take care to cover the area and wash your hands well after putting on the medication. Be careful not to let the site with the topical TT touch others because that could transfer the drug.
Testosterone is a steroid from the androstane class containing a keto and hydroxyl groups at the three and seventeen positions respectively. It is biosynthesized in several steps from cholesterol and is converted in the liver to inactive metabolites.[5] It exerts its action through binding to and activation of the androgen receptor.[5] In humans and most other vertebrates, testosterone is secreted primarily by the testicles of males and, to a lesser extent, the ovaries of females. On average, in adult males, levels of testosterone are about 7 to 8 times as great as in adult females.[6] As the metabolism of testosterone in males is greater, the daily production is about 20 times greater in men.[7][8] Females are also more sensitive to the hormone.[9]

Sprinting has been shown numerous times that it has positive effects on testosterone levels. One 2011 study (ref 84) looked at weightlifters who performed 4x35m sprints twice a week. In contrast to the control group (who continued lifting but did not sprint), it was found that “After the 4-week training program, total testosterone and the total testosterone/cortisol ratio increased significantly in the (sprinters) EXP group”.

In a recent study of male workers, men with low testosterone levels had an increased chance of severe erectile dysfunction (Kratzik et al 2005), although such a link had not been found previously (Rhoden et al 2002). Certainly erectile dysfunction is considered part of the clinical syndrome of hypogonadism, and questions regarding erectile dysfunction form part of the clinical assessment of patients with hypogonadism (Morley et al 2000; Moore et al 2004).
A: There are no over-the-counter products approved by the U.S. Food and Drug Administration (FDA) to increase testosterone levels. There are several prescription medication options available. Please consult with your health care provider in regards to your testosterone levels and to determine which treatment option best meets your individual needs. For more specific information, consult with your doctor or pharmacist for guidance based on your health status and current medications, particularly before taking any action. Kristen Dore, PharmD
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.
