increases intensity and pumps...usually put on about 5-6# with consistant use..."BLAST" by AST research is much more powerful to the CNS, but the pumps are not quite as good as with "Explode"...its worth the $$$ IMO...ive been thru about 5 containers so far...im not much on OTC products- but i will recommend this to anyone...however, if you do not uptake or have the affinity for creatine, it will only help with CNS stimulation...
