As an example (mistake I made) I used too larger dose when I was 19 years old.
I used 500mg/wk for my first and second. I used AAS far too early (around 180lbs) and got to around 200lbs after 2 cycles.
I then only played with compounds alone to see what side effects I got. I wouldn't count them as cycles per se.
My last cycle was 350mg/wk Test Prop and Dbol 20mg/ED for about 16 weeks. Got to around 220lbs 5"11 10-12% with my diet/training in order.
So I didnt NEED 500mg/wk at all.
350mg/wk Test was plenty and I was 20lbs heavier than I ever was using 500mg/wk.
