Coastal Peptides

Coastal Peptides was founded in late 2023 and launched in Q1 2024, supplying research-grade peptides for in-vitro laboratory use. Every lot is third-party tested with a verifiable certificate of analysis, and each vial label carries a QR code linking directly to that lot's COA. Researchers can confirm what they're holding without contacting us. Support is founder-led — questions about testing, documentation, or an order reach someone who can actually answer them. More than 70% of our orders come from returning customers, which is the clearest signal we have that the product and the process hold up. We built this as a long-term business with the standards to match.
