I have at least one unopened, if not 2 of the original tubs of the grape lying around. Stuff is crazy for sure. I dont use it much as it will keep my HR elevated in the low 100's for 8-10+ hours after I take it.
I save it for when I can catch an early workout. Stuff is nuts for sure.
1,3 is still available. Primaforce sells it in cap form (25mg) Cheap as hell....and combined with a little caffeine, you have a good pre-wo stim.
