I did a few cycles about two years ago. The last one had Trenbollone in it and I started getting gyno, so I cut it and started PCT. The lumps and sensitivity went away, but the puffy nips stayed. Something like six months after being off PCT, the lumps and sensitivity started coming back. I got some Letrozole and knocked it out again, tapering off real good at the end. I never felt quite right after all that. Like, my sex drive was shot for a year or so and is still not where it should be. Anyway, some months later, it comes back again. That time I ran Bromocriptine. Worked again and my drive came back up a little. Now, a few months later, the lumps and sensitivity started coming back yet again. I'm currently running Pramipexole, which is working, but I seem to have a serious problem with this crap coming back every 3-6 months for no apparent reason and my drive still isn't nearly where it was before I ever did any of this. WTF?
