Hi,Jerica
1 year is really not that long, you could have a growth spurt anytime within the next 5 years.
Progesterone will help, but from my own experience it tends to be more water retention, and doesn't last. It can also create depression or make it worse.
I was definitely bigger while on prog., didn't know it at the time but looking at pics back then, wow

but I have noticed now that I have more tissue, and there more rounded and there now back to the same size while on Prg.
I have had very good results with injections (takes some getting use to self injecting, NOT TO BE CONFUSED WITH SELF MEDICATING) but it is Estradiol not Prog. When I switched from patch to injections BOOM

the boobies starting growing.
Antiandrogens also play a big part. My breast are larger now then 6-months ago and there the same cup size. The difference is my band measurement went from an 31" to a 30" (actual measurements, not band size) I lost more muscle mass in chest area. I don't know how, most of my ribs were already showing.

All medications under Dr. care

P.S I just came across your You Tube site, it was linked to an orchiectomy site. I don't view too many of the Trans videos on YT. but I did enjoy yours. I was freaked out when I seen your before. The reason being you looked alot like me at that age, problem is I'm older now

.
The one thing that got me, was it seemed your cheeks filled out more, but that was pre HRT. I don't know if it was makeup or just the pics doing it. hmmmmmmm...
