Regarding dosage of PC that comes in a jar or other non-pump container... I have seen directions that vary from brand to brand, of 1/8 teaspoon to 1/2 teaspoon.
I think most say that a 1/4 teaspoon is a 20mg dose.

Here is an an interesting but long transcript from a podcast, entitled: How to Cycle Bioidentical Hormones.
https://progressyourhealth.com/podcast/how-to-cycle-bioidentical-hormones-pyhp-091/

It mentions that 20mg of progesterone is the natural level for a 28yo female.

Also discussed are the the differences between male cycles of 14 days and female cycles of 28.
They do NOT discuss males using female hormones. Their discussion in only on Testosterone for males.
Very interesting stuff and well worth the read, I think.
