thanks guys
I dont know if the slowdown in growth is receptors, or just your body getting used to something, from what I have learned, that would be my guess. Its like being hooked on coke, at first, a certain amount gets you high as a kite...then after a while it takes more and more to get the same result, and eventually you are taking tons, just to get back to normal...this is all because our body adapts really quickly....and as for growing, your body is only capable of growing so much at a time
The approach that I have been using from my trainer, is start at a low dose, then keep increasing it over the course of the cycle. So the dose I normally run all the way through the cycle, I didnt reach until week 8, so my body can never adapt to that amount that I am taking
