I know progesterone creams are sold over-the-counter, but I can't find pure progesterone, except that sold from biochemical vendors that typically just serve research institutions. I want to mix my own progesterone-in-oil to use topically and I believe it would be easier and cheaper to make my own, plus I can avoid many undesirable ingredients in the commercial creams. I would consider taking it orally (in oil) as well. The purity can be obtained from 97.5% to 99%. Is it illegal for regular people to buy this compound in this manner?I believe progesterone deficiency coupled with high exogenous estrogen mimics have caused my infertility, recurrent uterine fibroids, and weight gain. I've been using progesterone cream for about 3 or 4 months now.
