@albion I tried everything through the years, beside injectable.
For some reason, I do not have the issue with the scrotal application, but it doesn't convert to Progesterone, and it actually feels more like something else when applied on the scrotum, more like androgen like I would say.
There is a thread on the older forum from Haidut on progesterone on scrotum raising androgens.
This is funny though, as exactly two years ago I was just doing ok with a 50mg oral Preg SR from compounded pharmacy, and my levels always came back low without supplementation.
