Stanozolol is a derivative of dihydrotestosterone, although its activity is much milder than this androgen in nature. It is shown to exhibit a slightly greater tendency for muscle growth than androgenic activity. Stanozolol provides quality muscle growth, though the anabolic properties of this substance are still mild in comparison to many stronger compounds. Users report that the muscle gains they make are solid, and are well retained after use is discontinued. Together with a diet that is rich in protein Stanozolol gives the muscles a continuously leaner, harder appearance.

Structurally Stanozolol is not capable of converting into estrogen. Since estrogen is also the culprit with water retention, Stanozolol produces a lean, quality look to the physique with no fear of this occurring. In situations where one usually does not want to carry around excess water weight, one may find the raw muscle-growth brought about by s Stanozolol quite favorable over the lower quality mass gains of more estrogenic agents. This makes it very popular by athletes in combination speed / strength sports such a track and field.

Due to the product being dissolved in a water base, injections are necessary two to three per week, 50mg to 100mg per injection in most cases is an appropriate dose for men; for women the oral form of s tanozolol is more suitable.
