Yes, but it all depends on genetics. It isn't skull shape change, but fat redistribution, muscle (and ligament) growth and (I think) cartlidge growth.
I'm only a week and a half in, but I think (placebo effect?) I'm getting the slightest of changes already. FWIW, I had very high T levels beforehand.
I've noticed a very, very slight change in skin (more acne in new places, and I can see pores where I couldn't before) and I'm pretty sure the bridge of my nose has gotten slightly wider (enough that I see intents from the nose piece on my glasses where I didn't before).
Again, it's
very, very slight - I'd miss it if I wasn't 1. looking for it, 2. Taking daily photos, 3. Also noticed an extra 4 black facial hairs. It could still be all in my head though.
Goddamn I love T
Still... Hurry up and work faster you lazy T receptors! *Whip*
