a while ago a friend suggested i add 25mgs of viagra to my pre workout along with the NYC stack... ive never had better pumps than taking this combo! i felt like it probably wasnt a good idea to stay on this stack longterm for health reasons... so my question is there anything i can take to give me the same pumps? ive tried no explode, superpump, white blood, etc... they were all ok but nothing like what i previously mentioned... let me know guys
