Hey everyone, I finally have the resources to attempt a cycle of HGH. I have read up on everything on it, but am finding it difficult to understand how much to take. I am roughly 160 pounds and trying to add 15-20 of solid muscle to my frame. Obviously my diet and workout plans effect this goal, but how many I.U.'s would I expect to buy to take a 8 or 10 week cycle of HGH? Thanks.
