Does anyone know a source for amelogenin? How to use amelogenin?

[FatPanda]

This is a new peptide that is used topically in tooth paste or other methods to rebuild tooth enamel. I really want this as I had a bad depressive episode once and I have fucked up my teeth.

I found a few sellers on Google, and it looks stupid expensive. Looking for a better deal.

Also, if I were to buy this peptide, does anyone know how to use it on your teeth?

Does anyone know where or how to get this?
