It is legal because Primo is on a list with 26 other controlled anabolic/androgenic steroids, while 1-testosterone is not.

Also, can 1-test cause any progesterone complications or activate the prog receptors...??


None that I can tell. But we don't have all that much data on this hormone as it was never marketed, and was not extensively studied.
