are BCAAs necessary if you're using Osta-Red on a cut - by: Protoman

I have been using 12.5mg of Osta during my PCT in order to preserve muscle while still cutting. I ran a 6 week cycle of Halodrol (75mg) and 11-oxo (450mg) and am currently running torem / nolva / daa / arministane for my pct along with the 12.5mg osta. I still use BCAAs on days that I workout.

Just wondering if Osta negates the need for BCAAs to preserve lean muscle while on a caloric deficit?
