This is the "schools of thought" thing with progesterone. No one has absolute evidence for neither approach, except ton of anecdotes seem to point out that early prog start being a good idea. I did that, it never slowed down anything, let alone did anything "too fast", I started injections at two months, prog at seven months, I'm fifty six months on and well... See for youself.

I advice people to pick up prog as soon as they can or when they feel comfortable.

Powers is a quite controversial figure and I take his ideas with a grain of salt. Some interesting experimental ideas and ton of dubious bs coming from that guy. To his merit, he is one of the rare doctors who is willing to think outside of the box and try stuff out outside of the protocol. 

His stuff about understanding the trans fem experience however is a big load of bs, he is a cis man. He does not magically "get it". Having an understanding is one thing, claiming to know what we go through is load of crap. Only those who experience crippling dysphoria really understand how its like. Others have educated guesses and experience and then there's whole lot of lies. Its so typical of a cis male mansplaining trans fem experience. They're always the ones to know the best and to decide our fate which is totally wrong. If Powers was really smart, he would steer clear of such claims.

I say proceed with caution when dealing about any "facts" coming from him.

EDIT:
I read that Reddit post... Disgusting behaviour. And that's not the only such story either.
