I'm curious about this as well. I had to stop injecting after Oct 1 because I had to inspect parts in an ocean container that was covered in mold, and I got a skin rash because of it, and got scared of infection (sorry for too-much-info). Its been about two weeks and today I can definitely say I feel myself "coming down." All the positive effects I got from the super dose are gone (wellbeing feeling, confidence, nothing bothers me). And my weight is going down, after going up nonstop.
But this shouldn't be, because according to the PCT calculator I'm still at 500-600mg in my system (which would equate to a rough guess of about 1500ng/dl). I should start to feel the "coming down" when I go below about 125mg (probably even lower).
The only thing I can think of is SHBG is upregulated with the super dose of test, and SHBG stays high even as test drops.
