Getting ready to do my first show, this is the second time I posted this question hopefully I will get some response from someone who has tried this already. VPX Black Pearl is a no2 type supplement, I know this might not be the right forum but some of you compete and might know the answer: Will this supplement make me retain any kind of water come contest morning when I am pumping up. I get an incredible pump with this supplement, I am worried that I won't be able to suffiently get a good pump backstage before I go on. Any advice or suggestions??
