i used m-stack with Nano Vapor, might be a little diff from pump. But personally i found it was to much (m-stack and NO product both being pre work out) pretty sure m-stack has AAKG in it obviously pump would too. Saying that, every one is different so it might be fine for you, i just happen to feel the effects of NO and caffine really easily. Give it a go if you've allready bought it other wise maybe go with the NO product, if that gives you a good result then try looking for a test supp with out arginine or caffine. Again this is just me you might respond differently.
