I am guessing it's a variation of a prohormone....if you're doing this for health or long term then skip that stuff and do it the old fashioned way....if you want to get big muscles fast or want to have a big chest/biceps...then it doesn't matter b/c you'll soon get tired of it and quit...while messing up your health...so might as well just not do anything altogether..working out is a commitment....if you can't do it for the long term or waste time messing around with gear....then you're better off just doing other things...at least u won't mess up ur health more...
