Coastal Peptides is a functioning California research-material store with 33 complete reports from Kovera Labs and Chromate, established card and Cash App checkout, and FedEx shipping. All 33 reports have specific issuer records and name Coastal Peptides; 19 are source-current and 14 historical, with NAD source-version and CagriSema nominal-component conflicts kept outside exact current listing matches. 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 COAs and evidence
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.
01
Company and transparency
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.
02
Public Chromate report library
The retained archive contains 33 complete reports: 19 advertised as current and 14 historical, from Kovera Labs and Chromate. Every report has a specific official issuer record and names Coastal Peptides. Reports include HPLC purity and measured content; Kovera adds LC-MS identity, and blend reports include component measurements. Current CagriSema nominal components conflict with its aggregate labeled amount, and the current NAD card links a different report version from its attachment; those exact current listing matches remain excluded.
03
Independent testing and customer reviews
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.
04
Checkout, shipping, and returns
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.
