this product is a pro steroid, a steroid that has been chemically altered to stay legal. the product is a 17a steroid meaning it is hepa toxic and will damage the liver over time. This product is best described as a "wet" compound. reason being it carries a ton of water weight with it, the joints dont ache at all during use. although i did have bad back cramps while using this product. other then the back cramps and sweating i didnt have any other sides with it. If using you need to have a solid support supplement for during and after cycle as well as a well planned pct including a SERM. I suggest this product be used during a bulk as i didnt lean out much, but weight gain was fast and solid.
