Hey Bro, Finastride will promote hair growth, but if you are on a heavy cycle of test, or even deca watch your nips. I never get gyno, but two cycles ago I was running my usual 1G of test, .5 G of deca, and tren of course. Anyhow, I developed lumps. Never had them through all the years then bam! I hit the nolva's and bagged the finastride. It was the only thing I had added new. Luckily I'm back to an A cup, LMAO. In all honesty, I would steer clear of finastrideon heavy cycles. It will only add to your estrogen problems. Hope this helps. TY
