I believe so. I recomped for the 1st 6 weeks on Osta, then leaned bulked for the next 12.
Ended up putting on about 10lbs of muscle and losing 1.5" off my waist.
I took Tudca the entire cycle & tudca & nac during PCT.
Day 1 PCT bloodwork bilrubin was before completely normal, and ALT/AST were quite elevated.
Day 30 PCT bloodwork bilrubin & ALT/AST were all back to completely normal.
