Independent vendor review
Review profile checked 2026-08-27 · Independently fact-checked
Coastal Peptides scored across our four rubric factors — COA practices (40%), reputation, transparency, and operations (20% each).
Weighted factor result: 7.8/10. The published score follows the weighted result after rounding.
Direct answer
Coastal Peptides is a functioning California research-material store with 37 public Chromate records, six direct certificates inspected by PeptidePrices, established card and Cash App checkout, and FedEx shipping. Finnrick's strict independent dataset is older and mixed, while the available Reddit discussion is small and anecdotal. The combined evidence supports an 8/10 rating.

Evidence summary
Coastal Peptides appears legitimate as an operating store and earns strong marks for publishing direct Chromate records, retaining previous batches, showing products still in testing, and providing conventional checkout and shipping options.
The 8/10 rating combines an 8.5 for COA practices, 7 for reputation, 6.5 for transparency, and 8.5 for operations. The weighted result is 7.8 and rounds to 8. The COA verified label means that six sampled certificates resolved as direct laboratory records; it does not erase result-level limitations or prove every current lot. Match the exact product, strength, batch, result, and test scope before relying on a certificate.
What we reviewed, with the limits of that evidence kept explicit.
Coastal Peptides publishes support@coastalpeptides.com and a mailing address at 3943 Irvine Boulevard #231 in Irvine, California. Its domain was registered January 12, 2024. The site states that fulfillment occurs in California, but it does not publicly name an owner or a clearly identified operating legal entity. PeptidePrices treats the Irvine suite as a mailing address, not proof of a laboratory or warehouse.
The public test-results page listed 22 product groups and 37 published Chromate records. Twenty-eight cards cover current products, including Epithalon 10mg, Glutathione 1500mg, MOTS-C 10mg, and GLP2-T 60mg marked in testing; nine additional cards cover previous batches. PeptidePrices inspected six direct certificates for NAD+ 500mg, BPC-157 10mg, CJC-1295 no DAC 10mg, GHK-Cu 100mg, KLOW 80mg, and CagriSema 10mg. All six resolved as direct Chromate records, which supports the COA verified label. That label verifies the certificates, not a universal pass: BPC-157 reported 97.931% purity against a displayed >98% specification, CJC-1295 reported 96.947% against the same threshold, CagriSema did not list purity, and the sampled set did not show sterility, endotoxin, or heavy-metals testing.
Finnrick's strict independent page lists 26 older Coastal tests across five peptides, with its latest result dated March 28, 2025. Eleven classifiable tests passed and 15 failed, so PeptidePrices treats it as historical analytical context rather than a current catalog-wide verdict. An archived 2024 Reddit thread is small and mixed: one commenter said an order seemed okay, while others raised perceived quality or value concerns. Those anecdotes are reputation context, not laboratory evidence or a star-rating aggregate. The exact-domain Trustpilot profile is removed, so PeptidePrices does not reuse its stale rating.
Current checkout accepts Visa, Mastercard, American Express, Discover, and Cash App. It offers FedEx 2 Business Days for $15 and FedEx Overnight for $40, and it currently permits United States and Canadian addresses. The FAQ states free standard shipping from $250. Other policy text says US only and gives a different same-day cutoff, so buyers should confirm current terms at checkout. Sales are final after shipment, with damaged or incorrect items to be reported within seven days.
Decision guide
Customer reputation
Customer reviews describe service and order experiences. They do not prove identity, purity, vial content, sterility, or manufacturing standards. We keep them separate from COA and independent-testing evidence.
The archived thread includes one commenter who said an order seemed okay and others who raised perceived quality or value concerns. These anecdotes provide limited reputation context; they are not laboratory evidence or a customer star-rating aggregate.

COA status: COA ✓ with third-party testing. Coastal's public library listed 37 Chromate reports: 28 current cards, including four marked in testing, plus nine previous-batch records.
