Also, medical advice should be sought if the person has previously suffered heart attack, has a disease of the blood vessels or the heart, has high cholesterol levels in the blood, has clotting or excess bleeding problems, or has diabetes, kidney, or liver diseases. If the person has one or more of these problems, then an alteration of the dosage may be required. Medicines that can react with Winstrol are blood thinners or anticoagulants, diabetes medication, and insulin. Care should be taken while administering Winstrol with any of these medicines.
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.
