yes I know that. To elucidate I meant would I see better results using a stack like AX with the addition of creatine or are there certain products part of the nitro/testo stack, I couldn't seem to find much on whether alternative products would be needed. As for Pro peptide, some people say it's best used before bed as it's quite expensive as well and they use other protein powders during the day, say two shakes of whey.
