I agree with DormantFiber, the third week is kind of the "sweet" week. I did an epi cycle myself, I did 10 on day 1, 20 on day 2, 30 the rest of the first week. Then I bumped it to 40 till end of cycle; I had some really good gains too. My only issue with epi was the back pumps.....they freaking killed me, even with taurine. I just started a combined epi/revolt cycle. I started with 10/25 respectively, and already bumped to 20/50; I am on day three. I plan to go up to 40/75, plus I preloaded on taurine (2000mg). So hopefully with me still taking the taurine 4 times a day, that will eliminate the back pumps. Sorry for the long response. But to reiterate, by week three is when you should feel the real deal.
