Did first cycle of prop ,100eod, in may. Suffered back injury in week 6 had to cut cycle short. 5 bulging disc in lower back. Tried to work through it , was making it worse. At that time ended up in doc office and he ran bloodwork before I was finished with post cycle therapy (pct). Of course test levels were through the roof. I denied everything..scheduled bloodwork again but I didnt go until a month after I was done with my post cycle therapy (pct) (which was nolva 40\40\20\20)..My levels were much better but last week doc says my thyroid is off, on the low side. Wants me on thyroid meds..Could the cycle have thrown off my thyroid levels?.. Just got back on cycle two weeks ago...not sure what to do...want to finish this cycle...should be done with cycle and post cycle therapy (pct) by Jan...then have levels checked again....Main question ,Can cycle of prop throw off your thyroid levels? Can you be on a cycle of prop and on thyroid meds?
