Testosterone is a steroid hormone from the androgen group and is found in humans and other vertebrates. In humans and other mammals, testosterone is secreted primarily by the testicles of males and, to a lesser extent, the ovaries of females. Small amounts are also secreted by the adrenal glands. It is the principal male sex hormone and an anabolic steroid.

Testosterone for bodybuilding
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. Prostate enlargement, acne or worsening of acne, and acceleration of male pattern baldness (for those genetically susceptible to it) are more problematic with testosterone - again, in the absence of enzymatic control - than with many synthetics because of the effectively-higher androgen levels seen in these tissues as a result of local conversion to the more-potent DHT.

So, to minimize these effects, the choices for a highly-effective cycle that is low in side effects are to either control these enzymatic conversions with ancillary compounds while using testosterone at high dose; to instead use synthetics which do not undergo these conversions; or to combine moderate dose testosterone (100-200 mg/week) with synthetics.
