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 these injectable 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.
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!.
Testosterone used as the sole androgen is capable of giving very effective results, particularly with doses of one gram or more per week, and can give substantial results with only 500 mg/week. If no other drugs are used to control estrogen, however, side effects such as gynecomastia are fairly likely.
An anti-aromatase is preferable in a testosterone cycle to a selective estrogen receptor modulator (SERM) such as Clomid or Nolvadex for controlling estrogen because the SERMs either do nothing towards reducing effect of elevated estrogen in aggravating or causing acne, or themselves contribute adversely. Additionally, abnormally elevated estrogen levels may be deleterious for other reasons.
