The best Lab to send peptides/hgh to get tested for being legit?

[Walterwarrior]

I have three of the big research companies peptides as well as some Chinese hgh that I want to have tested for both being legit and contaminated with heavy metals. Does anyone know what independent labs offer peptide analysis? I heard of SGS in Canada will test products but I don't know if they deal with random individuals such as myself or only companies.
