Purple Peptides
Los Angeles-area US web shop (Ecwid store on WordPress) with some of the lowest single-vial prices in the US roster — BPC-157 5 mg $39, TB-500 10 mg $69, GHK-Cu 50 mg $49 — same-day USPS dispatch before 12 PM PST, flat $9.99 shipping and live stock counts on every product page. Current lots carry third-party Horizon Analytical COAs with UPLC-MS purity (99.12–99.79% on the lots shown), measured net content and endotoxin results. The problem is the older 'legacy' documentation: five certificate images are relabelled or reused across compounds and none carries a lot number — check the lot number on your vial against a current Horizon Analytical COA before relying on the documentation. All sales are final, the legal entity is given only as 'Pierce Purple P', and the brand has no public review history.

×Cons
- Five 'legacy' COA images are not what they claim: Epithalon and DSIP link the same relabelled retatrutide LC-MS report (#12052, C221H342N46O68, 4845 g/mol), Semax links a byte-identical copy of Selank's certificate, the CJC-1295 legacy report carries the BPC-157 chromatogram, and the GLP-3R legacy report was issued to another client ('A1 Bioresearch')
- None of the legacy BioRegen reports carries a batch/lot number ('N/A'); only the 2026 Horizon Analytical lots are traceable, and several products (TB-500, Selank, Semax, Epithalon, DSIP) still rely on legacy documents
- All sales final ('unless otherwise stated in writing'); replacements for damaged or incorrect items at the vendor's discretion
- Legal entity given only as 'Pierce Purple P' d/b/a Purple Peptides with no address or registration number; the privacy policy is WordPress 'Suggested text' boilerplate; the homepage FAQ still refers to 'Products from Direct Peptides' and the shipping page shows placeholder testimonials ('swap in your real ones')
- New brand with no public review history: policies dated January 2026, earliest certificates December 2025, Trustpilot profile claimed August 2026 with zero reviews
- US-only shipping, a 21+ age gate on every page, and no named payment method beyond 'third-party payment processors'
