Honestly, Sustanon is complete garbage. High-tech pharmaceuticals is known for taking herbs and trying to make them look like Pro-hormones. This stuff is straight up just DHEA. I would never recommend this product as it will not work. I wouldn't recommend taking this if you're looking to gain any size or strength. The only thing this could possibly be is a very weak test booster. With that being said I wouldn't waste my money on it and I would definitely go with something D-Aspartic acid based. People Byhardt high-tech pharmaceuticals because it's named after real steroids. It's very misleading and it's not good business. If you're looking for any good pro hormones I wouldn't recommend taking this. Overall I wouldn't recommend any high-tech pharmaceuticals products with the exception of their fat burners which are actually good. They went from the Sustanon 250 for now.
