About PeptidesNYC
Last updated: May 6, 2026
PeptidesNYC is a New York-based curator of U.S.-sourced research peptides. Every lot is independently tested by accredited U.S. laboratories and ships from the United States with same-day fulfillment on in-stock items.
In Partnership with PeptidesATX
PeptidesNYC operates in partnership with PeptidesATX, an Austin, Texas-based research peptide supplier. PeptidesATX handles fulfillment, quality control, and third-party laboratory testing for every lot we sell. PeptidesNYC focuses on the New York market: editorial product curation, customer education, and a clean purchasing experience for researchers in the Northeast. Together we operate as a single supply chain with U.S. sourcing, U.S. testing, and same-day domestic shipping.
What We Do
We curate a focused catalog of well-characterized research peptides for investigators studying metabolic, growth-axis, repair, cosmetic, and cognitive signaling pathways. Each item ships with the documentation researchers expect: lot identity, potency, and a Certificate of Analysis covering purity by HPLC and identity by mass spectrometry.
Quality Standards
- U.S.-sourced raw material, U.S.-staffed quality review.
- Independent third-party testing for purity and identity.
- Cold-chain handling for temperature-sensitive items.
- Sealed, lot-traceable packaging.
