Although Winstrol does possess a weaker androgenic strength rating than Testosterone does, androgenic side effects are still a potential risk, though much lower, and may only effect users significantly if they are especially sensitive to androgens. Androgenic side effects can include increased oily skin and acne, hair growth on the body, MPB (male pattern baldness), and BPH (Benign Prostatic Hypertrophy). The use of a 5-alpha reductase (5AR) inhibitor, such as Finasteride, Dutasteride, Proscar, or Propecia will be completely ineffective here, as Winstrol does not convert into DHT.
Stanozolol has been used by athletes for decades, especially by sprinters. This steroid has been known for giving sprinters more speed as well as allowing them to train harder and for longer due to quicker recovery from using Winstrol. A famous case known by many people is the sprinter Ben Johnson who broke the 100m world record, he tested positive for Winstrol and had his record removed. Football players as well as basket players have been known to use Stanozolol. Athletes looking for speed and strength as well as faster recovery often opt for Winstrol as its out of the body fast and so there is lower risk of being tested positive for Anabolic Steroids and also because the weight gains associated with Winstrol are not to high which is another benefit. Athletes such as sprinters need to be muscular and lean for achieve good speeds, if a sprinter gained 20lbs from a Ster0id cycle he would not be fast enough.
