Big lue! Ive been shoping for a while and honestly with every single PWO out there your probably going to be missing something you want and need and all ingredients will more than likely be underdosed! Its just how it is. Ive tried alot of preworkouts lately jack3d, asgt, maximize v2, white flood, presurge unleashed, muscle spike, 1mr, clout and body octane stack, xpand xtreme pump, anarchy, superpump 250 and i know im missing a few. ASGT being number 1 on that list for all around effect if it had a good pump complex it would be king in my eyes. Then the clout and body octane stack was an expensive but awesome stim free kick in the ass. If they could improve the taste of clout id be all over it. Why not make your own mixture man some creatine, BCAA, gplc, CM, BA, and you can buy geranium oil and caffeine to add stims if you need. Also add whatever else you like man thats just a list for starters. What about trying ULTIMA its stim free? Thats next on my list if it ever goes on sale again.
