I've had that problem in the past..here's what works for me..
I do 12 weeks on cycle, proviron 50mgs p/d and HCG at least for 1 week per month...at 500iu pd..with Nolv at 20mgs pd always.
The proviron helpls w the sex drive alot...and the montly hCG keeps yer nuts primed...after 12 or so weeks I go to 250-300mg test only(TRT) for 6-8 weeks with nolv at 10mgs, and I prefer to keep the pproviron also at this time ..but I just started using it and havent run it yet on my TRT weeks..
two other thingsthat can help with sex drive, Cabaser and Selegylene (l Deprenyl)..
