I took it for a couple of months. Made me feel like I could concentrate better and boosted sex drive. It has a very short half life and usually needs to be dosed 3x per day. I later switched to the selegiline patch.
I've taken Selegiline while on HRT and it did raise Test levels by a significant amount. The drawback was that it also raised Estrogen. It works on dopamine and when you raise dopamine, you raise Test and vice-versa.
