Epi 2a3a is a prohormone. Prohormones are supposed to have the same effect or nearly the same effect as steroids, without the long list of negative side effects. Epi 2a3a is a supplement sold by Vital Labs. The prohormone is not regulated by the Food and Drug Administration (FDA), despite the fact that many prohormones are considered controlled substances. The supplement companies simply changed the chemical formula for banned prohormones and released new hormones not covered until the bill passed in 2005. With so many potential formulas, it is hard for the FDA to keep up with all the new products and thus most slip through the cracks.

Prohormones are used by bodybuilders to increase lean muscle mass and strength. The effect on the body does not equate to reduced weight or decreased hunger. Dieters should be wary of the negative side effects associated with prohormones like Epi 2a3a. The ingredients are methylated, which means they affect liver function much like steroids. Prolonged use can lead to liver damage and permanent side effects.

Product Features

The product description for Epi 2a3a is common among prohormones. The supplement will increase lean muscle mass and strength, but what the supplement companies forget to tell the bodybuilder is the fact that the gains are not permanent. After taking a cycle of prohormone, the bodybuilder must take post cycle therapy supplement. These supplements are designed to preserved the strength and muscle gains while helping the liver recover from the methylated ingredients. In all cases, some strength and muscle mass will be lost during the post cycle. In some cases, all strength and muscle mass will be lost.

Prohormones are banned from bodybuilding and sporting competitions. Every year more and more athletes join the ranks of people who take supplements without “knowing” there are prohormones in the mix. The governing bodies do not take prohormone use lightly. In most cases, the athlete will be banned from competition, sometimes for life.

Epi 2a3a is a chemical alteration of a prohormone on the controlled substance list. All current prohormones have been altered in a lab to pass by the FDA, but that doesn’t mean drug tests will not pick up the prohormone. A simple alteration of a chemical formula may be enough to give the prohormone a new name, but it is not enough to surpass drug testing.

There are no prohormones considered safe for long-term use. All prohormones, even Epi 2a3a, should only be used for short cycles, typically 4 to 6 weeks. After the cycle, the bodybuilder must take post cycle therapy or they risk living with permanent liver damage. Prohormones do not promote weight loss.

    Looking to take a mild pro hormone that will no produce gyno and will help me achieve the lean, vascular, dry look. would this be a good choice for a supp. to help these results?



    I am on EPI 2A3A . It really works, In my 3rd week and gained 10lbs of solid muscleso far. I have losed inches in my waist and gained more strength.
