Honestly the s*** works great. Sustanon has me feeling good all the time what's the normal sides oily skin high libido good and strong every workout.... for me the NPP did way more than take care of some shoulder pain....It carved me up and tapered me everything looks bigger and Fuller yet not watery..... the s's really good I know the price makes people question the quality and I'm normally one of those people but this s is as good as any I've run and Ive run many brands over the years
