Ran it with a simple test c cycle and just had a overall better feeling of wellness. I usually get tired and lethargic while on any cycle and take naps but N2guard helped me with that which i have never had a supp do it that well. So no drowsiness, did not break out, and just felt like i had a little bit more pep so it was definitely worth it. Highly recommended, Acually used to take mens sport vitamins from GNC through the year and through a cycle and with the N2guard being cycle use specific it really showed me how much better it is to run a cycle support supp and recommended it to a bunch of gym rats down here.
