Hi Dru,
Here's what I know, too much estrogen stimuli fuses T.E.B's (terminal end buds).Though science says we only grow about 80% of TEB's, so this is good news for additional growth potential. Once girls get their first menstrual cycle progesterone is released (along with other hormones). We (here at BN) are trying to replicate puberty. If progesterone caused TEB's in early breast development we'd only A-cups out there in cisgender females. Here is Marcy and Oki, they both ran similar programs to mine and had great success. There's many others out that had PCs in their program (early on).
The naysayers (in trans care) who say progesterone doesn't help with breast is flat out wrong. I started using PC in the beginning of my program (see page 1). Even Valkyrie (@ freya's F cups) used pc in her program...we spoke many times via pm...and she started with a flat chest.
Look up Dr. Will Powers on reddit, hes a leading Transgender care Doctor (and family care) who knows the importance of progesterone...he even sells his own pprogesterone cream
