Well Epistane is usually used for a clean bulk or during a cutting phase....However you can still gain good quality mass from it...A good protein supplement is a staple of any bodybuilding type diet, along with Liver support, cycle support, PCT items and just a overall general knowledge of supplementation, nutrition, training and diet...If you are not yet familiar with these subjects then I would put the cycle on hold and educate yourself first...AM has a well of knowledge here. Take advantage of it.
