Progesterone so far has only been negative for me. I've experimented with it twice; once orally a few years ago for a ~4 month span, and once topically this year for another ~4 month span.
Orally I literally didn't notice anything, complete placebo.
Topically (cream) the first time I took it (a few drops rubbed into the wrists) I became quite fatigued and wanted sit down and stay seated for a few hours. The rest of the day (and every subsequent time I took it during the daytime) I was in a pretty negative head space, irritable, generally unsettled mentally.
Physically I noticed extremely little, nothing in the way of breast stuff, butt, nothing. The only things I think I noticed was a slight increase in body hair (arms, legs, pubic), and the skin on my face seemed thicker (comperable to pre-estrogen facial skin).
