Prohormones: Prostanozol is a non-methylated oral steroid. It was first introduced to the supplement market by ALR Industries in 2005, and later sold as GaspariNutritions Orastan-E. Prostanozol is a derivative of Winstrol (Stanozol).There is not a ton of information available on this compound because it appears to have never been investigated for medical use. It likely behaves similarly to Winstrol, although much less powerful. The exact anabolic and androgenic activity of Prostanozol is unknown, but it is likely to be fairly balanced. Prostanozol has no estrogenic activity, so side effects such as bloating and gynecomastia should not be too big of a concern. Other side effects associated with steroid use should be low as well due to the low strength of Prostanozol. One possible side effect of Prostanozol is lethargy due to low estrogen levels, because estrogen up-regulates brain serotonin levels.


Prostanozol, as previously mentioned, is very similar to Winstrol.

  • In fact, it is virtually identical to it except that, instead of being designed to pass through the liver, Prostanozol is designed to pass through the lymphatic system.
  • Prostanozol does not aromatize, meaning it does not convert into estrogen in the body and so it does not promote water retention or gynecomastia. This means the muscles look solid and thus Prostanozol is popular for cutting and as preparation for contests.
  • This steroid is also stackable with testosterone based cycles, as well as others.

Side Effects

  • Side effects can include negatively affected cholesterol levels, body hair growth, acne, oily skin, testosterone suppression, anxiety, increased blood pressure, and male pattern hair loss.
  • Women should watch out for a deepening in their voice, clitoris enlargement, menstrual irregularities, and body and facial hair growth.
  • If such changes are seen, the user should stop taking Winstrol as they may be permanent otherwise.
  • Many of these side effects can be prevented, controlled, or mitigated with supplements.

How To Take
For Body builders, it is recommended to take 100 mg to 150 mg a day for around 6 to 8 weeks.For women, 25 mg per day is enough for 4 weeks to 6 weeks.

Expert Tips/ Precautions

  • For first time users, it’s recommended to begin with 100mg daily then slowly work it up to around 150mg which is the most popular dosing.
  • Experienced users with past pro-hormone or designer steroid experience can experiment with dosages up towards 250mg.
  • When used in a bulking diet, users may see gains somewhere in the 3-5lb neighborhood on a 6 week cycle at 150mg.
