From the list of suplemments I've searched on the internet it seems like the more expensive are 1-AD and Myo-Blast. I've heard wonders about 1-AD, but I am hesitant to buy a prohormone yet. However, I read the info about Myoblast and it tells it is a natural product that increases the muscle fiber in your body and stuff. I would highly appreciate somebody to tell me a personal experience from the product.
