I love 4OHT because it does not shut me down. I kept me libido throughout the cycle. It's usually gone by week 3 of 1-test/4AD. I also got a lot less oily skin & acne. You probably will get slightly less gains than with 1-test/4ad, but I'll sacrifice that for the other effects. Its good stuff.
I will be adding a little 4OHT in all my future cycles as well.
