FWIW - I started using 10 mg of Pregnenolone creme just before bed around 90 days ago and it helps me sleep a lot better. I don't have true insomnia but I tend to wake often during the night and not always get right back to sleep. Progesterone has helped my sleep quite a lot. I have had blood work since starting it and it has not elevated my E2 in the slightest - which I know is a big fear many guys have around using either Pregnenolone or Progesterone. Now everybody is different and perhaps someone else would get a huge E2 spike off of it, but IMHO that fear could be overstated. Similar to how so many guys start TRT and are convinced that they are getting full-on gyno if they have one itchy nipple one single time.
