Letrozole will lower estrogen dependent on age 46-62% (46% in young men and 62% in elderly men) with a 46% rise in testosterone. Not as good as aromasin for PCT, but better than adex!
Yes letro is pretty strong. I think it even lowers the E further than 4th's research states if more then the theraputic dose is taken.
Oh I'm sure it would. I would def be careful when dosing any of these powerful drugs.
