Hey, still in my early research of this compound, and I know its chemical structure isn't 100% of the original that gtx Inc. Makes. Was wondering if its a good idea to use this to bridge the gap between on cycle and pct and maybe between cycles. It seems to have very little side affects and the ones that are present aren't much to concern myself with. Just want some info, from someone who has used it, any advice on lean gains, and maintaining those gains, improved joints, bone mass. Is it worth the purchase.... Thanks for any advice
