Cycling carbs, and starting low with the igf-1, have been up to 100mcg in the past with amino-outpost's peps and it was amazing stuff. I have to gauge the lethargy pretty much, I work in a physically demanding trade and the lethargy i felt before at 100mcg was really effecting my work. Also with diet i tend to do better on higher fat/protien/moderate carbs, keeping fat intake high to help natty test production. Macadamia nuts, almonds, avacado, red palm oil, coconut oil, almond butter, fish oil, whole eggs, all in the mix. Goals would be to recover natural test levels and keep fat gain to a minimum. Lifting heavy 4 days a week with jim wendlers 5/3/1 split with conditioning work on the other 3 days, heavy sleg drags and prowler sprints. I no longer am chasing size, i'd be content being more on the athletic side of things. To sum it up, i'd like to minimize the "crash".
