What makes Epi 2a3a by Vital Labs so "Popular?"

Epi 2a3a is the most potent, strongest, and purest Epistane product on the market, but Epi 2a3a’s trump card boils down to one thing… effectiveness!!!

One of the reasons for Epi 2a3a’s popularity is its versatility. It can be used in any cycle and can help you achieve almost any goal. If you are looking to cut, just make sure you are at a calorie deficit and watch yourself get shredded. If you are looking to add on lean muscle, make sure your diet is clean and that you are consuming more than you burn, and witness a transformation!

Don't take our word for it, check out the 100+ reviews!


What are the ingredients of Epi 2a3a?

Epistane - Epistane is derived from Dihydrotestosterone (DHT) and is an anti-estrogenic dry compound. A lot of excess fat is due to excess estrogen, Epistane will actually decrease estrogen through aromatase inhibition, which means Epistane prohormones are fantastic cutters!

On the other side of the coin, Epistane will bind to your androgen receptors which leads to changes in your muscle cell’s function. These changes result in increases in your muscle’s potential for growth and repair. Epistane will allow you to push beyond your genetic potential! 


Can I stack Epi 2a3a with other Prohormones? 


Yes you can! Stacking should only be done by experienced prohormone user's who have done at least one cycle in the past 6 months.

If your goal is to increase strength while leaning out and hardening your muscles stack Epi 2a3a with Halo-V by Vital Labs

If your goal is to bulk up, you will want to stack Epi 2a3a with Powerdrol 10 by Vital Labs

For extra dry lean gains and water shedding you can stack Stano-Shred by Vital Labs with Epi 2a3a.



Suggestions for use of Epi 2a3a:

Most users will run Epi 2A3A for 1-6 weeks starting with a 10-20 mg dosage for the first 2 days. The remainder of the cycle varies depending on desired results. Some users will ramp their cycle up week by week starting by taking 10-20 mg for the first week and increasing daily intake by an additional 10mg each week for 4 weeks ending at 40 mg daily. We suggest that for your last few days/week that you taper your dosage back down to 20 mg. 

Epi 2a3a is one of the mildest methylated prohormones, but that is no reason to overlook taking an on cycle support. Consider the fact that most people tend to run Epistane at a dosage amount much higher than the recommended amount, therefore, proper support is even more essential. Your best value option is going to be Protex by Vital Labs.

Due to the fact that Epi 2a3a is a dry gainer and a cutter, a common side effect during cycle is dry joints. Your body will be shedding water like crazy! Drink a minimum of a gallon of water a day, and take a joint supplement so you don't get achy joints from them drying out. Joint and Tissue by Myogenix is your best option for this.

Aside from dry joints, the only real side effect is "Rebound Gyno," but if this occurs it is after the prohormone cycle. This means that your body has experienced a very high suppression from estrogen that when your body is off the prohormone it produces an excessive amount of estrogen to compensate, thus leading to estrogen related side effects like Gynecomastia. This is an uncommon side effect, but when it does occur it is typically due to user's running it at an extremely high dosage (50 mg+ per day). To help combat this, it is suggested that you use Post Cycle 3X by Vital Labs for your PCT as it has Indol-3-carbinol, which helps convert bad estrogen to good estrogen. 

If you are extremely concerned about Rebound Gyno, during your PCT stack Post Cycle 3X by Vital Labs with Estrogenex by Hi-Tech Pharmacueticals or Estro Strike by Assault Labs.

Make sure once you have completed your prohormone cycle that you take an additional 30 days off before starting another cycle. Feel free to Contact the Pros at if you need support with your cycle or need help planning your next one!

Far Exceeded Expectations Review by strooperx

Wow! First ever PH cycle for me. Expected to put on 5lbs or so and improve overall muscle tone. I went from around 215 or 220lbs to 237! Seemed to kick in at the end of the 2nd week. I actually nearly stopped on the 4th week because it was working too well. Friends and family were calling me out for using steroids. No significant side effects - I was tired most of the time, and into the 4th week my muscles would cramp up really easy when I flexed them. Otherwise, I felt great. I was able to work out far sooner than usual, and got major pumps in the gym. The muscle I put on is lean, toned, and hard as a rock. I understand my results are not typical, but I 100% would recommend, and will try again.(Posted on 10/10/13)

Epi 2A3A Excellent Review by Mike
Epi 2A3A was amazing. I've been lifting for 17 years and have never had results like this. After 1 week, you could already feel it kicking in. I was lifting 275 and shot up to 305. At the same time, I was eating everything (not always clean) but leaned out and dried up like crazy. Abs came out, striations, and muscle definition. I would highly recommend this product. (Posted on 9/24/13)

Gained 12 pounds of lean muscle, boosted my bench 45 pounds, increased stamina and libido.
Very few side effects, other than 1 or 2 days of back pumps and a migraine was the cycle was completed.
** Must take a cycle support product and a good PCT **
Beginners may not see results until week 3, depends on your dosage and experience using Epistane.
Beginner dosing week 1 & 2 (2 per day) week 3 (3 per day) weeks 4-5 + 3 days (4 per day). Advanced users week 1-4 (3 or 4 per day)

Quick question. Im going to run epi for 6 weeks. 4 weeks at 30mg and the last two weeks at 20 and 10mg then use nolva for pct at 25mg. i know nolva doesnt destroy estrogen, justs blocks it. And epi was already lowering my estrogen. So, i was wondering if the estrogen will just build up and rebound after since my estrogen has been lowered from the epi and then blocked off with nolva and im shut down and all that. or is it fine with that as my cycle and pct?
I have read on many websites that Epistane can cause hair loss. This is my main concern so I wanted to know if its true?
I have high blood pressure and my friend has HIV. Would be still be able to use this supplement?
I was wondering about running a 2 month cycle. I haven't run one before but am looking into starting with EPI 2A3A, then following with EPI 2A3A again stacked with Haldrol. I was wondering what the usual dosage would be when stacking them together for each, or if I'd be better doing one at a time. Thanks.

Astonishing product
  • Have you ever had a girlfriend that left you and you didn't know what to do? Thats how i felt when i took my last pill of Epistane.

    This is a profound pro-hormone. For starters, I'm 20 and this was the first pro-hormone iv'e ever done. The goal of mine was to pack on some muscle and shred my excess fat. I was assuming my weight of 170LB was going to be dropped about 10LBS. But in all reality i gained 15LBS of rock hard muscle putting me at weight of 185LBS. While cutting 5-7% body fat, and don't get me wrong here I had a insanely strict diet. I copied some of my girls meal plans for her upcoming bodybuilding show lol. Lean sources of protein were (AM: Whey protein shake, Tuna, Chicken, Quest bars, Lean red meat, ground turkey and for nighttime a Casein slow digesting 8 hour release protein shake). 6 low carb days (under 100 carbs) and 1 re-feed day (Sundays at 250+). I was eating my food like a mad man and turned into the hulk at my gym when i had intense training days. I would do cardio 5 times a week, do cardio in the morning and muscle groups at 5:30PM with the boys.

    A follow up of my results on this cutting pro-hormone was a bench press max of 275LBs at the body weight of 170LBs, sky rocketing to 330LBs at 185LBs. Squats went from 315LBs set of 2-3reps to 405 (maxing set). Another thing i want to touch face on is the amount of vascularity that has happened the past month. WOW, it's disgusting- I have a formula 1 race track on my arms and legs. Im talking from the ankle all the way up my quadriceps. And My transversals, AKA "Money makers" have the most vascularity, which is a girls favorite part of the body, Score. lol.

    I have been asked by, i kid you not, ATLEAST 10 different people if im "juicing" or taking steroids. And how blunt they were about it is just mind-blowing. On my 5th and final week I got that question at-least 2 times a day. And it's the most rewarding-(fuck you haters) feeling that you can get, baby! This product has a insane amount of potential if your willing to train dirty and eat clean. I busted my ass on this shit and I have people coming up to me for steroids now at the gym, that i don't even know on a personal level. Just keep your mouth shut and let the Epistane do the talking.

    Ahhh, the PCT. The hands-down MOST IMPORTANT part of this experience. I have talked to a lot of people in and out the gym about there takes on PCT. If you want a promising resurrection of your natural testerone levels, then go get some fucking Nolvadex (Tamoxifen Citrate) and don't be a dumb-ass. Brutal honesty is needed for this topic because I can't stress enough over the amount of idiots that said "fuck a pct" or did it wrong. Second off, stack a testorone booster to with your PCT to make it as potent as possible. IF your PCT is right and i said "IF", then you will NOT plateau after your on-cycle and continue to sky-rocket in the gym and fuck shit up.

    This was my awesome experience on Epistane and I hope I was able to help all of you idiots that do steroids, like me. Because there fucking awesome. I'll be doing a bulking pro-hormone this December after 2 months rest from my Epi, Hope you guys make fantastic gains.

Works as advertised
  • In short - It works

    My honest review in detail -

    First off, great website. They shipped my products to Europe in only 4 days! I was impressed.

    I have weight trained for years. However, after a few months off I started up again and was gaining 1kg of muscle/week naturally for 3 months until I hit a hard plateau. I decided to try my first cycle and chose Epistane since it's known to be mild.

    I started my cycle at 91kg (200lbs), 11% BF and now about to start my pct after 5 weeks on Epi. I ran it 30/30/40/40/40 spaced evenly throughout the day. I am now 99kg (218lbs) and 10% BF. I can definitely notice the weight gain however it doesn't look like 8kg's worth, likely from increased muscle density.

    My diet was near perfect, in a surplus of 4000-4500 kcal/day and 250g of lean protein. I worked out hard 6x a week and got lots of rest otherwise. I wanted to see the limits of what this PH could do.

    My experience -
    I didn't feel it really kick in until day 16, later than I was expecting. Half of the weight I gained was in the first week, probably water however I stayed dry. My strength improved mildly in the last 2 weeks but nothing major.

    Pro's -
    -A very noticeable increase in muscle hardness and a CONSTANT pump. After an 8hr sleep I would wake up with arms that are full and hard like steel bars. A bigger pump than even after my best arm workouts previously.
    -I also noticed a mild but noticeable increase in aggression and confidence which I liked. I would get easily annoyed with a very short fuse. Overall I felt more powerful and energized.
    Notable increase in muscle mass, definition and striation, particularly in my arms, shoulders and chest.
    -I am in my 20's but I have a receding hairline which halted during this cycle.

    Con's -
    -Immediately I started experiencing off and on lethargy that continued daily throughout the cycle. I would go through a daily roller coaster of energy and motivation, followed by extreme fatigue/tiredness and laziness. It wasn't until the 5th week that this leveled off (as my body adjusted).
    - Once it kicked in around day 16 I started getting extremely dehydrated. I would drink about 8 litres of water each day and still feel thirsty. My toilet got a good workout. Make sure to always have a water bottle with you! You will need it. It wasn't until the 4th week that I realized a lot of my lethargy and headaches could be remedied with drinking even more water.
    -My libido increased slightly for the first 2 weeks (which I loved) but then dropped off quickly to the point where I almost had constant ED issues (I'm in my mid 20's). This is my biggest complaint with Epi as with all the new attention I was gaining, when girls kept asking to come back to my place, I had to come up with excuses why they couldn't because I knew I would have ED.
    -With my loss of libido I lost some of my motivation and drive for training, but kept going anyways.
    -My sleep quality declined immediately and stayed poor throughout the cycle, it made me restless. In the last 2 weeks I was so dry that I would wake up every 2 hours feeling like a mummy and desperately needed to drink a bottle of water.
    -No cramps, no back pumps (but I did supplement with Taurine so that helped a lot, recommended), no joint pain (I used fish oils and a joint aid supp)

    Overall -
    -I am satisfied with my results with Epi and would consider another cycle in the future. I am really going to miss this insane pump that I've gotten used to and how hard my muscles are constantly. It definitely broke my plateau which is what I was looking for.
    I am about to start my pct (with PostCycle 3x and Nolvadex) and hoping to maintain most of my gains. For now though I am looking forward to my libido returning, being easily hydrated again, and getting some good nights of sleep.

    Remember your on cycle liver support, have your pct ready and I would recommend taurine and fish oils to prevent sides. This stuff works!
  • Increased muscle gain, extreme muscle pump and density.
  • Dehydration, lethargy, sleep issues.
