What You Should Know
A prohormone is simply a precursor to an actual hormone. When alone, the prohormone does not have a significant impact on the body as it works with the hormone for maximum effect. Prohormones are typically used in the bodybuilding community to bypass the laws surrounding anabolic steroids. Steroids are illegal, but prohormones aimed at increasing testosterone levels are not. According to the claims behind prohormones, the body will transform the prohormone into the real thing when metabolized. This means that prohormones would not be illegal under steroid laws, but in 2005 that changed. Former President George Bush signed a bill that listed many prohormones on a controlled substance list. Some of the prohormones listed include androstanediol, androstenedione, androstenediol, formebolone and drostanolone. This is not a complete list as the complete list contains many prohormones.
List of Ingredients
Precursor to hormones in the human body.
There are some prohormones that work as described in the body. 4-Androstenedione, for instance, converts to testosterone at a rate of 6% in the body. So 6% of the 4-androstenedione taken ends up metabolizing into testosterone. 4-Androstenediol has a higher conversion rate of 16%. Both of these prohormones are now considered controlled substances in the United States.
There remain many prohormone supplements on the market today claiming to include legal ingredients that convert to testosterone. Many of these supplements will have the word “Test” or “Drol” in the name such as HaloTest-25, Methyl Masterdrol and H-Drol. Other popular prohormones include MMv3, 17-Diol and Isa Test.
The reaction of prohormones in the body differs from one to another. The bodybuilder can rest assured that the prohormones on the market today are not highly effective or they would be included in the controlled substance category. Typically, these supplements will include ingredients with long scientific names such as 4-chloro-17a-methyl-andro-4-ene3, 17bdiol present in HaloTest-25.
Prices for prohormones are all over the map. Some manufacturers sell their products for around $25 and others more than $100 a bottle. There have even been some companies forced to remove products from the market due to banned ingredients like Gaspari Nutrition’s Halodrol-50.
- Prohormones may transform into testosterone in the body.
- Not all prohormones transform at high rates.
- Most effective prohormones are now considered controlled substances.
- The price range for these supplements is huge.
- Dieters will not see any weight loss effect from prohormones.
- Women should not take these products.
Most of the prohormones that used to legal for use in supplements are now controlled substances and thus can no longer be used in any natural formula. This left supplement manufacturers running to the lab to create new testosterone prohormones, but the end results were nowhere near those banned.
