In its own words: “At Kyin-Peptide, we believe in the power of science and nature to transform skincare. Our journey began with a simple mission: to develop innovative, effective products that harness the potential of peptides. We noticed a gap in the market for high-quality peptide formulations that deliver real results, and thus, Kyin-Peptide was born.”
Kyin Peptide publishes 6 certificates of analysis on its site. The vendor chose which batches to publish, so those results do not tell you what is in the vial you receive.
Prices run from $49.00 to $133.00 across 8 listed products. Payment is by credit card. Orders ship with DHL and USPS. Quoted delivery is 7-14 business days to Worldwide.
Worth knowing before you order: consumer email only and no research-use-only notice. Every contact address is a free consumer mailbox ([email protected], [email protected]) rather than an address on the company's own domain. There is no registered business identity behind the contact route.
