This is one of the best reviews ive read in a while, and Ive read a lot of them. I am currently using the C4 and NO3 stack and I am in heaven.! I have never had a more fuller pump and more strength in the gym than I do now. I am serving in the United States Army and currently in Afghanistan. Everyday in teh gym the other guys ask me what I am using, and I tell them… They are all big supporters of BSN NOXplode and I used to be also, But now a supreme supporter of CELLUCORE!!!! Afer I cycle off of the NO3 and C4 im going to give theyre cutting stack a try with the D4, T7, and L2 products!!!
