i've been running a cycle with testosterone enanthate 600mg a week and trenbolone acetate 150mg eod for the last 6 weeks, the cycle is of 18 weeks and i'll be bringing on arimidex from this week onwards and then move on to PCT with clomid and nolva. should i also make HCG a part of my cycle? if yes, when exactly and would 250iu twice a week be good?
