test. only cycles actually work better than stack cycles for me. whenever i stack test with soemthing, my gains are shit until i drop the other drugs (i.e. fina/test cycle), then i blow up. i think it has to do with the two drugs competing for the androgen receptor. in some cases, the dose response curve can actually plateau, then go back down, which is what i think happens with me. so for me, it's 500-750 mg/week test only cycles, forever. no more fancy shit.
