I picked "used in pct and recovery phenomenal" but I want to clarify- My sex drive, energy and testicle size recovery was "normal". I've done enough cycles to recognize and expect a certain time frame for recovery given doses etc. With s4 I retained an amazing amount of gains, gained strength and my bf didn't jump up as it usually does post cycle. That's what made it phenomenal. As far as actual "recovery", that was normal. i.e. s4 didn't seem to affect my natural test output reocvery and so forth- but held gains and helped a "bit" with energy etc.
For sex drive and general sense of well being I used DHEA along with S4 and Clomid. Never felt better or retained more gains!
