Yes bro, I would certainly change the program up. I'm sure that with you're experience, you have seen homeostasis creep in as a cycle progresses. I make cycle changes every several wks. Either upping a dose or adding a compound or switching a compound. I'll switch test esters every 8 wks. Maybe start with sust, then move to Cyp. I'll run a long acting anabolic like EQ through a 16 wk period but in the first 8 wks, may use NPP, then in the 2nd 8 wks, switch to tren. Change is good.
