Libido and troubles with follow through/finishing are common to both PCS and meds. Low testosterone can also be at play. It only takes a very small amount of topical testosterone cream rubbed on a hairless body area to increase sex functions. If you rub some T cream on an area that has hair, the hair growth will increase and even become coarse. You need a doctors script for T cream. DHEA supplements daily can help your body produce T. I take 25 mgs of DHEA a day.
