I have ordered from several Chinese peptide suppliers but decided to use one rated on peptide critic. Bad idea. Every company I have ever ordered from it took 2 weeks from china and great communication throughout. These guys do not respond to emails. Except a email 3 weeks later saying sorry some of your items didn’t ship. Well a month later still no tracking info and have ordered and received my products since from a different Chinese vendor ordered a week and a half ago. Never again.
