Study on Bioidentical Hormones - Progesterone v Progestins
So the British Menopausal Society has briefly made public its report on cBHRT (compounded bioidentical HRT) against rBHRT (regulated biodentical HRT) and it goes into detail about the benefits of progesterone vs synthetic compound progestins.
For future proofing i've transferred it to a google doc:
Progesterone v Progestins
The report also states effects:
Deep Vein Thrombosis: Progesterone lowers chances, Progestins raises.
Cardiovascular: Progestins can raise cholesterol, increase insulin resistance, reduce arterial compliance. Progesterone does none of the above.
Breast Cancer: Progestins increase risk, Progesterone does not.
