"Finished 8 week cycle. Same experience as Chemical One: lifts went up, did more reps/sets every workout, gained weight, and generally felt pumped all the time. I wish this was available when I was competing in powerlifting and Olympic lifting. I can't say I felt a big enough difference between Chemical One and Four to recommend one over the other. I'd try both and see. Either way, I've kept the strength gains from Chemical Four, but lost a little weight which I expect is water since 4-DHEA is more androgenic (and I assume leads to more fluid retention). Chemical X next! "
