At its simplest, Epistane or “Epi” – as it’s commonly called in the business – is a type of prohormone that’s a derivative of dihydrotestosterone (DHT) and shares similar features with epitiostanol.

It is crucial to keep in mind that Epistane listed as 2a,3a-epithio17a methyl-17b-hydroxy-5a-androstane is considered as a “clone” and can convert into Phera-Plex, an illegal substance, when it is left in storage for a prolonged period of time.

Unlike most anabolic steroids that have to be injected in the body to get their magic going, Epistane is taken orally – which is way more convenient compared to the former – to set off considerable gains in lean muscle as well as pick up the pace on the synthesis of protein in the body that translates to a distinct increase in overall strength levels.

Just to give you an idea of how Epistane works, it basically binds to androgen receptors that are located in muscle stem cells and skeletal muscle cells. When this happens, these androgen receptors send messages to cells to boost their retention of nitrogen and protein synthesis, which improve strength and muscle mass.

What’s even more interesting is Epistane is a c17-alpha alkylated analog of epitiostane, which has been proven in a number of clinical studies as having anti-estrogen effects and has little ability to aromatize. However, it isn’t an aromatase inhibitor or AI in any way.

Given the fact that having too much estrogen in the body can lead to unwanted fat gain, bloating and water retention, you’re sure to keep clear from these issues when you’ve got this prohormone in your arsenal. It is considered by a lot of experienced users as comparable to anabolic steroids like Turinabol and Winstrol.

This is the reason why Epistane has become quite popular as a bulking and cutting cycle agent all rolled into one. It is important to keep in mind that this prohormone isn’t recommended for use by women for bodybuilding purposes.


Here is a quick summary of the benefits of Epistane;

  • Promotes dry and hard muscle gains

  • Boosts overall strength levels

  • Helps get rid of unwanted fat

  • Can help improve general well-being and libido

If you’re a first time Epistane user, the recommended dose is 30mg daily. Since this prohormone usually comes in 10mg capsules with an average half-life, you’ll need to dose up three times a day in 7-hour intervals, with the very first one taken upon waking. This cycle should be run for 4 weeks for optimum results

Potential Side Effects

What’s really interesting about Epistane is it doesn’t set off the usual negative side effects triggered by its prohormone counterparts like aggression, acne outbreaks as well as sudden increased hair loss or hair growth, which makes it a top choice for newbies.
