So, you want monster muscles and are willing to turn to a supplement for support? EpiCat claims to help put muscles on your muscles with just two powerful ingredients that can help inhibit muscle breakdown and increase muscle mass. Your biggest limiting factor is in your genetics, according to Blackstone Labs, and they say EpiCat can help change this.

Commonly found in the household, the ingredients of green tea and cocoa are the compounds in EpiCat that aim to unlock your ultimate bodybuilding potential.

So, what is in EpiCat and how will it help your bodybuilding goals? It’s not a prohormone or steroid, but it claims to have a similar anabolic effect on your muscles. Containing just two ingredients, The Muscle Watchdog reviews EpiCat and its contents, to see if it really can make you the physical freak it promises to.

EpiCat Pros

  • Green tea is widely thought to provide many health benefits and Epicatechins are showing promise in supporting muscle gain

EpiCat Cons

  • Expensive product considering it only contains two ingredients
  • Human scientific studies are lacking to prove that the ingredients can have a positive effect on muscle gain
  • Side effects may be experienced as a result of taking this supplement

What You Need To Know About EpiCat

Blackstone Labs have manufactured EpiCat for hardcore bodybuilders looking to see significant gains, and who are already putting the hard work in with their diet and lifestyle. They say that the missing piece of the puzzle is often genetic limitations and that is what EpiCat aims to address.

It contains green tea and epicatechins, usually found in dark chocolate, which are thought to help lower myostatin levels and increase follistatin, which is responsible for that shredded look every bodybuilder wants.

Between the fat burning thermogenics of the green tea and the muscle building capability of the epicatechins, this supplement claims to be your best buddy in combination with an appropriate diet and exercise programme.

However, it does only contain two ingredients, one of which has very little human evidence to prove it works, so perhaps the jury is still out on this one

What Are The Side Effects Of EpiCat?

Possible side effects include insomnia, nervousness, and headache, at the less serious end of the spectrum, with irregular heart rate, convulsions, and confusion at the more serious end. This is mainly a risk associated with long-term heavy use of caffeine, which is contained within green tea and can be present in cocoa.

How Much Does EpiCat Cost?

You will pay $64.99 for one bottle of EpiCat which contains 60 capsules, around one month’s supply. It is available to purchase as a one-off via the Blackstone Labs website and on Amazon. Blackstone Lab has a wholesaler programme to sell its products, where distributors earn commission on products.

Our Verdict On EpiCat

In our opinion, epicatechins hold some promise in their ability to create the chemical changes in your body that possibly may increase muscle mass. However, so little evidence exists that it is impossible to say this will definitely work for you.

Green Tea is a more common ingredient in fat shredders and physical performance products and has shown results in thermogenics, potentially leading to fat loss and a more defined look.

It is quite a simple formulation compared to other products on the market, which seems bold and could either be a positive if it works, or you may not see any results at all.

Overall, we do not recommend EpiCat to our readers.

EpiCat Review

EpiCat claims to be a revolutionary supplement that will build all-natural muscle mass. If genetics is not on your side and you are struggling to gain muscle, this product says it will ‘flip the genetic switch’.

EpiCat Facts

  • Aimed at the bodybuilding community with the sole aim to achieve gains and shred fat
  • They use wholesale distributors to scale up their product sales, and sellers earn a commission on EpiCat
  • Comes in a capsule for ease of use

Clearly, this is a good marketing ploy and it is not possible to change your genetic code, but the chemicals contained with green tea and epicatechin could help you fight nature by increasing the compound required to stop the breakdown of muscle and promote the growth of power.

How to Take EpiCat

Take one capsule up to twice a day but do not exceed two capsules per day.

The results in mice have been promising but so far the human studies are lacking, and there are not reliable results to assure you this product will work.

EpiCat Concerns:

  • Prolonged use of caffeine can have some unpleasant and/or serious side effects
  • There is little scientific evidence to back up this product’s claim but epicatechins do show some promise in maximizing muscle growth
  • Contains a higher dosage of green tea than experts recommend

This product is manufactured under the Good Manufacturing guidelines but is not governed by the Food and Drug Administration to back its claims.

What Does EpiCat Claim To Do?

EpiCat says it will transform your bodybuilding experience by challenging what nature gave you and enhancing your top-notch diet and exercise efforts.

The formulation promises to give you a two-pronged attack, first the Green Tea provides the energy you need to kick your gym work up a gear, as well as putting your body into thermogenesis which will shred fat, allowing your natural muscle tone to show through.

Secondly, it says it will inhibit Myostatin and increase Follistatin, which are human proteins that affect muscle mass and your ability to achieve gains.

Does EpiCat Work?

Epicatechins are exciting the supplement world due to its potential and in animal trials, seem to have shown some increase in physical performance. There are yet to be any reliable human studies that can replicate this effect though, which means that for now, epicatechins are a bit unknown. The experts say that they are generally thought to provide other health benefits when consumed in dark chocolate and green tea, so perhaps its worth a try.

This product contains a lot of green tea, with the usual recommended daily dose being around 400-500mg daily. Whilst it may be effective in increasing energy, it causes some concern that with prolonged use it could cause a range of nasty side effects. Taking this product in a morning and not exceeding the dosage is critical, in our opinion.

What Are The Ingredients of EpiCat?

  • Green Tea (700mg): Typically known to be a powerful anti-oxidant when consumed in large quantities. Camellia sinensis comes from a plant typically grown in China and now in other parts of Asia due to its popularity. The leaves are commonly steeped in water and drunk to get its benefit. It is often used in dietary supplements as it reportedly enhances metabolism, fat oxidation, and may trigger thermogenesis, important for fat burning. It is also being tested as a stimulant that can improve memory and is often used in exercise performance and recovery. It is expected that doses of around 400-500mg daily is significant enough to provide benefit, but it does depend on the type and makeup of the tea. There may be side effects of taking this in concentrated measures, such as insomnia, headaches, and may interact poorly with dietary Iron, so may not be suitable for people with anemia. It may also interact with blood pressure medication and high cholesterol.
  • Epicatechin (300mg): An exciting ingredient being trialed in bodybuilding, that is taken from dark cocoa and green tea, typically. It reportedly works by inhibiting Myostatin, which can eat away at muscle and suppresses muscular potential. Epicatechin can provoke the opposite reaction by decreasing Myostatin and increasing Follistatin, which indirectly promotes muscle growth. Trials have found some success in this area but only in animals. Further human studies are needed to show if there are any reliable effects of taking Epicatechin regularly. Whilst there are no known side effects, there are other health benefits to eating dark chocolate which contains Epicatechin. Women may also wish to be careful taking this supplement in case it does raise testosterone levels.

Does EpiCat Have Any Side Effects?

There may be some side effects as a result of consuming green tea, owing mainly to the caffeine. Green tea is also thought to interfere with Iron intake, unless supplemented with vitamin C, and can affect cholesterol and blood pressure.

Others commented they ‘did not feel any difference’ and were underwhelmed with the supplement.

Does EpiCat Offer a Money-Back Guarantee?
