Description :

As a bodybuilding drug, testosterone is almost always used as an injectable ester, due to poor oral bioavailability and the impracticality of high dose transdermal or sublingual delivery. Testosterone also is provided as an injectable suspension. Discussion here is in reference to theseinjectable preparations. Pharmacologically, testosterone acts both via the androgen receptor and via other means. In practice, it is found to combine synergistically both with those anabolic steroids categorized as Class I and those categorized as Class II, and therefore is described as having mixed activity.Particular properties of testosterone that are of note include that it converts enzymatically both to dihydrotestosterone (DHT) and to estradiol (the most important of the estrogens.) 

While with normal levels of testosterone and normal enzyme activity these conversions are in fact desirable, with supraphysiological testosterone levels caused by drug administration they can be undesirable. DHT is at least three times more potent (effective per milligram) than testosterone at the androgen receptor (AR): therefore, in those tissues which convert testosterone to DHT, there is effectively three times as much androgen as elsewhere in the body. Thus, whatever level of androgen is experienced by the muscle tissue is effectively multiplied threefold or more in the skin and in the prostate. This can be excessive.

If you really want to boost your natural testosterone levels, and receive all the benefits that come with it ie. greater muscle mass and strength, improved endurance, enhanced recovery etc. It is the most important product you will ever use!.

Applications :
With regard to inhibition of the hypothalamic/pituitary/testicular axis (HPTA), 200 mg/week of injected testosterone is approximately 2/3 to 3./4 suppressive, while 100 mg/week is about 50% suppressive. For this reason, low dose testosterone use is not particularly efficient, as natural production is already “worth” 100-200 mg/week, and this is mostly lost with the first 200 mg/week of injectable that is used. The particular synthetics which are low-suppressive are, for this reason, more efficient for low-dose use than is testosterone.

With use of an anti-aromatase, 600-750 mg/week of injected testosterone is a good dosage range for a novice. Without an anti-aromatase, it may be preferred to limit usage to 500 mg/week, although there can be risk of gynecomastia at doses even as low as 200 mg/week if no anti-estrogen is used. More advanced users may favor a gram per week. Still-higher doses such as 2 grams per week generally provide only a small further increment in performance, with that generally being noticeable only if a plateau has been reached at 1 gram per week. Amounts higher than this are employed by some pro bodybuilders but probably with only a slight further incremental effect.
