I only use reliable sources, I do lots of research on the source, read reviews and pm members on thier results, but you never really know till you try the compound. I pay to have my diet and training planned out for me based on my age, weight, height, compounds being used and current goals, I train hard and dont cheat. So either I dont respond well to DBOL or its bunk, in either case I dont want to invest anymore money on it, time to move on to something else
