never tried metaformin tabs but seems to work very similar AP. has anyone tried both of these. if so which one worked better? i was planing a metaformin/gh combo in pct and am thinking maybe i should change it to gh/AP. the more i've been reading on this supplement i think i'm going to have to try it. i have a couple guys at my gym that i help with diet and supp routines and will be ordering cissus/AP stacks for them to try. i guess i will see the real verdict soon enough.
