Me: Hey Ray! I know you've mentioned in the past that large doses of progesterone can lower libido for men but can it cause feminization for men as well? Like not just neotenous features but breast development and wider womanly hips.
Ray:No, it can’t do those things.
High doses of progesterone do tend to have anti-androgenic effects and that is something he has said repeatedly. Also, you can test this yourself. Try a 100mg progesterone dose and see if that won't numb your penis or lower libido. These side effects disappear or can be greatly lessened when progesterone is combined with DHEA or even T.
