I agree it will inhibit your recovery for sure. I been reading about the Ostagain, sounds like something that would be good for pct to help with libido and more. Not sure has a positive or negative affect on test levels though.
You can use it for that purpose, lots of guys do. You will get mixed opinions as to shut down. My experience is that it does not hinder recovery. There is some literature that it increases sperm count. It does lower estrogen and give a good libido boost. Bromo or caber is great for libido and will help with recovery.
