Epistane, also sold under the name Havoc, can be found under the nomenclature 2a,3a-epithio-17a-methyl-5a-androstan-17b-ol. This steroid is known for providing decent gains in mass and strength without much subcutaneous water retention. Epistane seems best suited for bulking cycles, but it can also be used for cutting cycles.
Epistane does not convert to estrogen and actually acts as somewhat of an anti-estrogen, so no estrogenic side effects should be experienced which is the main reason why Epistane can be used for cutting cycles. Epistane is best for bulking cycles because it is excellent at increasing glycogen stores in the muscle when sufficient carbohydrate is present in the users diet. Because of this effect some of the weight gained on cycle will be lost in the weeks to follow but there should not be as drastic of a weight fluctuation as seen with some other prohormones such as M-Drol.
Epistane is popular for bulking cycles and also recomposition cycles where that goal is to both build muscle and burn fat. Most users experience decent gains in both strength and lean mass with Epistane with some portion of the weight gained being lost in the weeks following the cycle. Epistane is generally lower on side effects than many other prohormones and the combination of this with the decent gains in mass and strength it provides make Epistane a popular choice both for first time prohormone users and those running more advanced cycles.
