I already tested osta @20mg/day for 6 weeks with no suppression (did a blood work after) 1, 5 year ago.
That's why I wanted to use it in my PCT to try to keep strength as much as possible. After just one week, I even feel stronger than last week (to be confirmed next week of course).
If I still feel not recovered at all next week, I will drop osta as you advice me
