In my experiences, as well as many others, IGF 2 is better suited for a bulk. you get more mass gains from IGF 2 vs HGHup as HGHup does give LBM gains, it decreases quite a bit of BF. Free Test is optimal for a bulk but can be used to cut. If you are going to take Free Test, take 2 bottles. You can take Drive, but if you are just simply bulking, i would want you to spend your money on a product that would help you bulk. sometime like AnaBeta or DAA (Lit Up)
