Dbol can, Test can, Tren can, Anadrol can, very high dose Deca can...perhaps others at high doses as well.
20-60 mgs of daily divided dose (every 7 hours) Tamoxifen can get rid of it.
Some have had success with 1500 mgs a day or more of Vitex stopping and/or getting rid of Tren or Deca induced gyno.
The Tamoxifen has been a God send for me.
I've had two gyno surgeies, the first in '94. I wasn't on anything at the time and hadn't been for 2 years, but my gyno had been there since age 17 or so (about the size of a nickel-then exploded over a few months to about 2" diameter).
Then, for some unknown reason (no AAS involved at all) in late '96 it started coming back. By March '97 it was bigger than it had ever been (maybe 3" diameter). I had it removed AGAIN!
Then, around Sept. 2001, I took some Prohormone shit (Andro & Trib), and *poof* gyno came back! I stopped the prohormones immediately. The gyno started off small, then exploded again to about 2" diameter in early '02. I got some tamoxifen and after about 3 months...no more gyno.
