this product is a pro steroid, meaning it is a steroid that has been chemically altered to be legal. It is a 17a steroid meaning it is hepatoxic and wrecks havoc on your body. It will put on a ton of mass, and strength will go through the roof, but the sides are near unbarable. sides ranged puffy nipples, agression, irratibility, oily skin, sore joints, back cramps, high BP, i didnt get blood work but im sure my lipids were out of whack as well. If you do decide to use this product make sure you use a solid support product during its use and make sure you have a PCT including a SERM as well as more support products for the pct itself. this is a dangerous product and personally i do not suggest it to anyone at all, well planned cycle or not.
