By the way, i wanted to thank you for the research you shared here, it is pretty interesting to see how trans people end up with the same mammary glands as cis-girls if they take progestative antiandrogens!
You're welcome, I'll definetly have more time next week for sure, I'm having back surgery (to make repairs) early next week. So if I make posts that are gibberish you'll know it's the pain meds talking.
There's a difference between USP progesterone and wild yam progesterone. USP progesterone is bioidentical (as in made by humans) as opposed to wild yam made in a lab. WY isn't progestative, apologies. Though in the absence of using estradiol it helps with aveolargenesis (ductal growth).

Here's some research I put together based on science literature. Progesterone suppresses activation and crosstalk between PR (progesterone receptor) and prolactin/Stat5 signaling to inhibit milk protein gene expression. These changes are reflected in reduced activation of JAK2 and PAK1, resulting in downregulation of pSTAT5.
However, MSM stimulates the activation of the Jak2/STAT5 signaling pathway to help secrete milk protein. MSM also stimulates GH (growth hormone) induced activation of Jak2/STAT5b and prolactin production.
Why is this important?, progesterone downregulates the Jak2/STAT5 pathway that inhibits milk proteins and affect terminal end buds (TEB's which are the branch like structures that fill out breasts) growth and alveologenesis. Taking MSM helps to restore what progesterone destroys during its protein metabolism. We also learned progesterone is catabolic to protein expression in breast tissue. Now we can address this catabolism (breakdown of proteins) by adding amino acids to the mix...possibly tyrosine and proline to strengthen the protein loss. Or possibly consuming more protein in our diet.
