Prohormones have more side effects. Prohormones have more side effects than steroids. Some, if not most prohormones formulas were tested and rejected by drug companies because of their health risks.

Prohormones are taken orally. Oral steroids are always far worse on the liver than injected steroids. Prohormones pass through the liver, and are very liver toxic. This chemically induced liver damage, known as hepatoxicity, is primarily caused by the larger percentage of molecules that have a methyl 17a by weight compared to conventional oral steroids.

Prohormones are less effective. Prohormones are less effective than steroids. You are taking a higher risk for smaller gains. Many prohormones are poorer, lab-rejected versions of popular steroids.

Prohormones are not thoroughly researched. Anabolic steroids have been researched on both man and animals, and have a long track record. On the other hand, there is very little prohormone research. The lack of research on prohormone substances presents too many uncertainties. Using prohormones makes you a lab guinea pig.

Prohormones are legal. Easier access means cheaper cost, and generally more abuse. Especially for beginning lifters. Beginners generally don’t use steroids for a number of reasons…no access to them, fear of jail, etc. But it is extremely common for beginning lifters to use prohormones, long before they learn proper training and diet.

Summary. Do your research before messing with prohormones. Prohormones should never be used by those under the age of 21, nor by beginning lifters. Maximize your natural potential before you even consider prohormone use.
