"Epiandrosterone is the 5b-isomer of androsterone. The 5b isomers are typically much weaker than the 5a ones and often are more estrogenic too. In the case of epiandrosterone, it is an actual agonist of the estrogen receptor beta, and is a very weak aromatase inhibitor compared to androsterone. It is also a much weaker agonist of the androgen receptor. Finally, the studies that used both epiandrosterone and androsterone to test their metabolism showed that androsterone readily converts into DHT, 5a-androstanedione, and epiandrosterone while epiandrosterone only converted to androstanediol and 5b-androstanedione but no DHT.
TLDR: epiandrosterone compares to androsterone similar to how how 5b-DHT compares to 5a-DHT. The latter is the real deal, the formed is a weaker metabolite. The 5a-steroids is where it's at for men and androsterone is a 5a-steroid while epiandrosterone is a 5b-steroid."
