PHARMA STAN 50 (Stanozolol) by Pharmacom Labs is currently the most micronized stanozolol on the market, allowing for the use of any needle type and various muscle groups for injections. Highly valued by dieting bodybuilders and competitive athletes, it is almost exclusively used to great effect in cutting cycles rather than bulking.

Stanozolol, also known as Winstrol, is a 17-alpha-alkylated derivative of dihydrotestosterone (DHT) with low androgenic qualities and high anabolic properties. Developed in 1962 by Sterling-Winthrop Laboratories, it was initially used to increase lymphocyte count and CD8+ cell numbers while decreasing CD4+ and CD3+ in postmenopausal women with osteoporosis. It has also been used to treat hereditary angioedema and influence immunological processes.

Stanozolol is available in two forms: tablets and injections. It is the second most widely used oral steroid, following methandienone. Tablets have a short half-life (about 9 hours) compared to injectable stanozolol, which is an aqueous suspension of fine steroid particles rather than an oil solution. This results in unusual pharmacokinetics with a sustained effect that tapers slowly, lasting at least a week.

As a DHT derivative, Stanozolol does not convert into estradiol, eliminating the need for aromatase inhibitors and preventing water retention. Instead, it has a diuretic effect, producing a lean, quality look without excess subcutaneous water retention. This makes it ideal for cutting cycles, where eliminating excess water and fat while achieving defined, hard muscles is the goal. It is highly regarded among strength/speed athletes like track and field competitors.

For bodybuilders, Stanozolol has the unique ability to lower sex hormone-binding globulin (SHBG) levels, enhancing the efficiency of other steroids in a stack by increasing the amount of biologically active free testosterone in the blood. It is advisable to always use Stanozolol with testosterone. However, Winstrol may increase tendon brittleness by drying out joint fluid, leading to joint pain and damage. Both forms of Stanozolol can also adversely affect cholesterol levels, so monitoring lipid profiles during the cycle is recommended.

In summary, Stanozolol is generally recommended for athletes with sufficient muscle bulk who wish to improve endurance and increase muscle relief and hardness.
