Bro, I sense a lot of anger and hate. Although I don't have super intelligent opinions on the cases you presented, we do see good results with peating on hair. I also wouldn't call Hans a non-Peater. Yes, he does few things that are not fully peaty but his general view on health still aligns.
This guy from Hans group showed his results in such a short time with the following routine...
"Gut health - ALA, bone broth, berberine, l-ReuterI
Topical - copper peptide, whipped beef tallow (it’s my moisturiser but used it topically)
Dermaroller - 5 min a day"
Some of your questions remain valid though and I'd like to see things like that in the Peatosphere.
In general in the health and fitness scene, there are always countless ways to reach a goal and goals are reached with differing and opposing methods that do not make sense for dogmatists. In that, I hear you brother. But we have to acknowledge the triple power of placebo, drastic change, and confounding variables. You won't see me embracing PUFAs after seeing guys regrow hair while eating PUFA.
Cheers
