Honestly,I haven't been able to pull up data on OT's overall metabolism. The limited amount I found seemed conflicted, some saying first pass literally destroyed a huge portion of active compound, then another saying metabolites were in high concentrations renally (kidney). So I'm on the fence. We need some guys to run bloodwork on OT, lol.
I will tell you what i ran blood work on tbol about 4 days into pct and all my levels where off the scale of course the insurance comapnt had no idea I was on aas so they assumed it was alcohol.
