I think, I'm going to go with the cream, to start with at least, and see what happens.
We can compare notes

However based on the graph that I have, it should be something like:
Day 13,14, 15: 3000mg PM
Day 14,15,16,17: an equivalent amount of circulating Prog ( however you achieve that?)
Day 16,17,18 :2000mg PM
Day 19: 3000mg PM ( secondary peak)
Day 18-26: Diminishing Prog. down to nothing.
Day 20-28: Diminishing PM down to 500mg per day.
Day 1-12: Ramp PM back up to 2000mg/day
Day 13: Back to the start with sudden increase to 3000mg/day PM.

The worrying thing about this is that again it has the P right on top of the E, which si natural but at odds with the perceived wisdom of NBE

How is your experiment working?

Seems to me the question is, since development of breast buds seem to happen prior to a woman's first period, when (if ever) should you try to mimic the typical female hormone cycle? Personally mimicking the female cycle seems to be asking for problems. It might be best to check existing Male to Female transitioning hormone schedules / therapies to see what is currently working or the party line on adding progesterone to the regimen.
