what is better for the periosteal apposition

19nors or dht derivs?

both are binding to the AR receptors, i dont understand the difference

AR binding ≠ identical effects. Dht derivatives are non-aromatizable, while 19-nors have a different hormonal profile, so bone effects can differ despite both binding the AR.

To answer your question; 19-nors have a stronger theoretical case than DHT derivatives for bones

why do then people rather inject mast but not tren for the higher bone density, makes no sense to me

People don't use Masteron for bone density. They use it for a dry, hard physique. Tren may have a different effect on bone, but it's avoided by many because its side effects are much harsher. Infact the choice isn't based on periosteal apposition
