basically i have done 4 cycle first being prop/var second enanthate/d-bol third sust/deca/anavar and fourth prop/oxy's/winny all at average doses first obv being the smallest however i did not run an AI on my first cycle had no issues till i hit pct and then got slight gyno nothing major about the size of a pea and hopped on arimidex and sorted it out, so from then i have used arimidex throughout cycles at .25mg ed but i have never managed to get as much weight gain as i did on my first cycle i gained a total of 18lbs ! and that was prop 100mg eod and anavar 70mg a day for 8 weeks, recent cycles i have not gained no were near as much and last cycle didnt gain too great although it was a lean bulk so wondering if arimidex could be hindering my gains ???? i have slight lumps under my nipples from preveous cycle finished 2 days ago but no biggie very small and not sensitive they seem to go after a while.
