Stanozolol (also known as Winstrol) is a C17-alpha-alkylated derivative of dihydrotestosterone (DHT), effective orally, with low androgenic but highly anabolic properties. Sterling-Winthrop launched stanozolol on the prescription drug market in 1962 under the trade name Winstrol. Stanozolol has been prescribed as a medication for various purposes, including preserving bone mass in cases of osteoporosis and increasing muscle mass in cases of weight loss associated with medical conditions. Bodybuilders consider its remarkable ability to reduce sex hormone-binding globulin (SHBG) an interesting peculiarity; by significantly lowering SHBG levels, it considerably increases the effectiveness of other steroids in a cycle. As a DHT derivative, stanozolol cannot aromatize into estrogens. Therefore, stanozolol does not cause water retention; it may even have a diuretic effect. This makes it an excellent steroid for use during muscle-defining cycles to reduce excess water and fat, as well as whenever achieving defined and hard musculature is a primary goal. Stanozolol's ability to promote strength and muscle growth without water retention makes it highly valued by dieting bodybuilders and competitive athletes in strength and speed sports.
WARNING: Stanozolol is known for its ability to dry out synovial fluid, which can lead to joint pain and damage. Do not train with maximum loads while taking stanozolol. Combining testosterone with stanozolol may help alleviate this effect by retaining some water. Additionally, stanozolol can cause adverse changes in the lipid profile. Cholesterol levels (HDL and LDL) should be kept under control during the cycle. Due to its C17-alpha alkylation, stanozolol can overload the liver. The recommended duration of a stanozolol cycle should not exceed 6 to 8 weeks.
