I suggested drol because ot doesn't bloat me as bad as most other orals. But, should be able to control it pretty easily with a AI. I dont suggest stacking a whole bunch of orals just harsh on your liver and no point. Honestly if you wanna stack something else I would do another injectable. Probably EQ if I was you I noticed a distinct stamina increase and vascularity. How ever if you go this route I would push the cycle out to a minimum of 10 weeks.
Also just a side note Tren Ace has not hurt my stamina to bad how ever I'm not a endurance athlete but, I'm sure the endurance could easily be maintained if you were working at it and also drugs like T3 at a low dose have been successfully used to keep stamina high while on it. Just a suggestion to research.
