Epi 2a3a Review - 5 Things You Need to Know


If you haven’t looked carefully at Epi 2a3a, now’s your chance. We took our time to create a comprehensive review, focusing on the side effects, ingredients, customer-service quality and scientific studies. Then we analyzed numerous consumer comments from all over the internet. Finally, we condensed all the data we gathered to give you the facts.

Epi 2a3a Readers: Click here to find out why we're giving away samples of our product, Burn HD.

What is Epi 2a3a?

First off, Epi 2a3a is a prohormone. These products are like steroids but are alleged to have fewer negative effects. They are not regulated by the FDA but have shown up on drug tests administered to athletes and body builders, in some cases. If they do show up it is typically enough to cause a penalty or suspension.

Epi 2a3a is made by Vital Labs. The company specializes in products that utilize prohormones. The marketing material from the manufacturer indicates they specialize in designing items for hardcore athletes, but read on…

Side Effects – “A Concern?”

Our first concern is the potential for Epi 2a3a side effects. Per our Research Editor, “Products that utilize prohormones chemically like steroids work through the liver. It appears that prolonged use is not suggested.”

An unhappy purchaser related, “I took these for a cycle and my cholesterol levels were wrecked. Not worth it.”

One disgruntled shopper quipped, “I developed hypertension while I was on my first go around with this. I had to give it up.”

Some thought the chances of side effects were minimal.

A satisfied individual pointed out, “This type of thing will give me headaches sometimes but it’s worth the payoff.”

While another offered, “I’ve never had any trouble with this or anything like it. Works great!”

Availability– “Minimal”

Of significant concern is the fact that the manufacturer no longer appears to be offering Epi 2a3a directly.

This person mentioned, “I’ve used this in the past and I liked it. I haven’t been able to reorder lately though.”

Which was echoed by a man who said, “Even my secondary source says he can’t get this anymore. Weird.”

Not everyone is concerned with the difficulty in obtaining Epi 2a3a.

A more optimistic commenter decided, “I’ve used it several times in the past and it was fantastic. I don’t mind making the effort to hunt it down.”

Another added, “I haven’t tried to reorder in a while but I’m sure the company will address any shortages.

According to our research, potential side effects and availability are important to shoppers and could have an impact on chances of long-term success. If Epi 2a3a has a negative impact on the customer, that could be enough to stop them from sticking with it.

The Science – “Not There?”

At DietSpotlight we want to find science to back up a product’s or company’s claims. With Epi 2a3a we didn’t find anything and the business behind the prohormone is no longer selling it, so they’ve no reason to share any.

The Bottom Line – Does Epi 2a3a Work?

What’s the read deal with Epi 2a3a? There is no way to know for sure how well this product worked when it was still being produced and distributed. Even though there are some positive reviews and the company is generally well respected, we are hesitant to give our support if only because the information we were able to find was vague, at best.

If the time has come to find a way to naturally boost your testosterone levels, we recommend trying a supplement that is formulated with clinically tested ingredients that are safe and effective.

Among the best products we’ve seen this year is one called Pronabolin. It is formulated with a combination of nine key ingredients, which have been clinically shown to help maximize energy and boost testosterone levels. We were unable to uncover any negative reviews but we did find numerous people sharing their great results.

The company that makes Pronabolin is so confident about the quality of their product they’re offering consumers a 120-day money-back guarantee in addition to  multiple-bottle discounts. Excellent!

What You Should Know

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.

List of Ingredients

  • 2a,3a-epithio-17a-methyletioallocholanol

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.


  • Will temporarily increase lean muscle and strength.


  • May cause an athlete to fail a drug test.
  • Not designed to improve weight loss.
  • May have negative effects on the liver.


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.
