I just got vpx no shotgun out of curiosoity. It seems like it would be approximately the same as noxplod or something like that. It has several creatines and caffeine as well. Anyways has anyone used this before? I know some NO products are just a scam but with this I cant even finish my last reps cause my muscles ache so much and i kind of feel light heated when i get going, not in a bad way though, its more like a tingle. I dont know haha its just kind of weird and i was wondering if anyone else experienced similar things. Thanks, Johan
