Shit is rough on prostate..im using it through out cycle... and having a hard time pissing.... pluss..it takes me still a LOng time to get off.... im hard alot but..not too sensetive ttc... sucks... I will be ading Omnadren to my cyle Immediately.....for sex drive 250- 500 mg.. and BTW DONT ever go over 100 mg..... that was my mistake........one errection i was like oh shit.... i got a ll tense..and nothing came out.... and hurt like ***** like as if it got cloged up..and backed up i could feel it... i though t i dammaged myself..but few days later it went away... watch your doses ....and it does take a few days to kick in ..so if 1 day your not hard dont do 2 dose next day... bump i tup slowly ..and see how it goes... also..i find that too much proviron is bad for sex...im just to fuckin hard.... my unit is desensetized..and i jsu t am not fellign to much sensation..thsi may be due to low test though.... Just my experience....Peace
