I'm on TRT level of test. I started using hcg to regain fertlity. I use it MWF 250iu-500iu. I notice a drop in libido harder to maintain erection. I'm also using 25 mg of proviorion ED and about ten other supplements. HCG throws me off. This happen to anyone else. I've never been a fan of AIs they flatten me out too much I usually use masteron prop on cycle.
