Someone had posted this study a while ago showing finasteride upregulated IGF-1 in some patients: https://www.ncbi.nlm.nih.gov/pubmed/12894070
TL;DR the ones who had upregulated igf-1 while on finasteride regrew hair or maintained, and those who didn't have upregulated IGF-1 had their hair worsened. Small study though
IGF-1 works locally from where it's injected, i'm curious if anyone has tried scalp injections.
good luck getting real IGF-1 without paying an arm and a leg, the stuff is almost as expensive as HGH.
Half these compounds would probably be useful, but the only people "trying" them are the same people who seriously believe the chinese sold them real thing for bargain bin prices, or that 90 iq bodybuilders running a criminal webshop to pay for rent and prostitutes are above giving you garbage to turn a profit.
