@JTOATJOWHLOR it's very safe, one of the safest things you can take. There's no known level of toxicity or overdose.

VERY important to verify that is it actually bio-identical progesterone. And not a synthetic progestin.

If your run into any issues, I'd highly recommend the Estrogen Dominance Support Group on Facebook. Very Peaty and lots of advice/experiences on progesterone
