Estrogen
Mestranol is a type of estrogen that works by activating estrogen receptor alpha. It is a small molecule that can be taken orally. While some studies suggest it might affect genetic material in certain cells, tests using the Ames Salmonella method did not show significant increases in bacterial mutations.
How it worksMestranol works by acting as an agonist for estrogen receptor alpha, meaning it mimics the effects of natural estrogen in the body.
