I used Ostarine a few years back after doing a traditional PCT that Prae prescribed for me and I did like it. But I think any increase I had in sex drive was from the HCG , Nolva , Clomid and HMG that I had run just before the Ostarine. I am currently running Ostarine with 200mg test e, 300mg EQ and 2IU GH and have virtually zero sex drive . Everything else is good though.
