I'm only on day 4 of bodyoctane, but I could tell from today's arm workout that the product is starting to take effect, as I experienced an absolutely insane pump in my biceps, easily rivalling those felt on my previous superone+ cycles. Mind you, I'm also using BN cee, as well as BSL nitrojet, but today's pump was much more intense than those I've experienced the previous 4 weeks of my current bulking phase. I can't wait to see/feel the effects as the weeks continue, but I can already tell that this is one supplement that you can really feel the effects of.
