When I was on methadone, it made my testosterone levels plummet - my already low sex drive (I feel like masturbating sometimes) went to 0 (I no longer feel like masturbating ever), and i got Bob's bitch tits.
They gave me delatestryl injections. Testosterone, steroids. My arm muscles got really big, I could suddenly do 20 pullups without even feeling winded after, and Fuzzy Bunny noticed strange black hairs growing where there were no hairs before. And I felt like masturbating again.
That's it. I didn't become this rabid horn dog willing to go up to women and ask them out. I didn't really get any extra confidence at all, just physical stamina. There was no change in my perceived "manliness", and most of these types would have probably still called me a wuss while I was on the steroids.
