I have run pretty much all gear in every way when it comes to trt...personally I like to run low dose test with mast or primo...to be honest I think most of us run gear constantly through the year for me if I drop to 150 test cyp then add mast in with it at a low dose also when I ramp up I switch my compounds to like test primo npp I always go low test around 400 when on cycle then add npp 500 and primo 700 as long as I switch stuff up I do well
