If you blast and pct of course it makes it harder to recover, but not impossible in most cases and the younger you are the more chances you have.
I blast Testosterone 350mg/week for 6-8 months at the time now, then return to high end trt of 150mg for 3 months. For now it is enough for me. Possibly due to my age and genetics. Time will tell more.
I could possibly use that much Testosterone without any breaks by donating bloods regularly. As my bloodwork is still passable on such amounts of T.
The only reason I don't let myself that, is that I want to come off to TRT some and rest, not just for health, but mental too.
During the august I will taper off in to TRT slowly and begin again mid december. So counting in the tapering off phase, I will be on a true trt for 3.5 months before I blast again.
