I used one box of Halodrol and I have seen increases in weight, muscle size, definition, and strength. I would highly recommend this product.
Give the current environment in which PH have to be developed to meet ban requirements, this product really stands out. I can only speak for myself, when I started a 209lbs, and just finish the cycle I'm at 228lbs...and strong as hell. Stack it with good BCAA, Protein, and a solid creatine...and you'll put on the pounds and add substancial strength
