Methenolone study

Alfatradiol binds to the ERα and ERβ with 58% and 11% of the relative binding affinity of 17β-estradiol. [13] However, it has 100-fold lower estrogenic activity relative to estradiol, [14] which may in part be due to differences in the intrinsic activity of the two compounds. [ citation needed ] On the other hand, alfatradiol has been found to bind to and activate the brain -expressed ER-X with a greater potency than estradiol, indicating that it may be the predominant endogenous ligand for the receptor.
