California Proposition 65 Notice

Statutory disclosure for shipments into the State of California.

Last updated: 28 July 2026 · v1.0

⚠ WARNING Some products supplied by Peridyn Labs may expose you to chemicals — including trace impurities such as lead — known to the State of California to cause cancer, birth defects, or other reproductive harm. For more information visit www.P65Warnings.ca.gov.

Why this notice exists

California's Safe Drinking Water and Toxic Enforcement Act of 1986 (Proposition 65) requires businesses to warn Californians about significant exposures to chemicals on the state's list of substances known to cause cancer or reproductive harm.

How it applies to Peridyn Labs

The chemical impurity most commonly relevant to peptide reference standards is lead, a trace by-product of the manufacturing process. Peridyn's third-party heavy-metal panel (USP <232> / <233> by ICP-MS) reports lead content on every lot; the Certificate of Analysis is the authoritative source for a specific lot's elemental impurity profile.

Additional information
