halo extreme needs a pct...you cant fully recover on osta rx as it does suppress the hpta too some extent...
NO PCTIV in PCT. It contains ostarine which is suppressive. This is becoming a major issue on multiple boards now.
I would use nolva (20mg) or clomid (50mg) daily for 4 weeks followed by E-Control to prevent estro rebound.This does not surprise me(the issue of confusion)as bsl recommends pctIV for all their pct as far as i remember.
As for pct with the cutting stack of ostra and halo for 4-6 weeks would you have to use something like clomid or nova or would the econtrol and test boosters be enough?
