COA & lab verification

COA ✓Third-party testedView Lost Coast Aminos's COA page ↗
Read the testing and verification notes

Lost Coast Aminos publishes a broad, product-and-batch-linked third-party report gallery from Kovera Labs, BT Labs/BioTools, and Freedom Diagnostics. PeptidePrices inspected current Kovera reports for SLU-PP-332 10mg batch LCA-07172026SLU10 (report KVR-2026-F286CE) and Cagrilintide 5mg batch LCA0526CGL5 (report KVR-2026-5F6994), then confirmed both records in Kovera's official lookup. Those reports list identity, purity, measured content, endotoxin, sterility, heavy metals, and three-vial conformity. A sampled BT Labs BPC-157 20mg report lists FTIR identity, 99.8% HPLC purity, and 20.4mg potency, but explicitly excludes microbial and endotoxin testing. Panel breadth therefore varies by report, and some gallery records predate the newest catalog lots. The checker now carries a Lost Coast partner fingerprint for the known Kovera and BT Labs formats. Match the exact compound, storefront alias, strength, batch, report date, report ID, and panel. A report does not prove that a received vial is the tested lot.

Evidence summary

Why Lost Coast Aminos is rated 9.5/10

Our conclusion

Lost Coast has strong public laboratory documentation for a young vendor. Two current Kovera records matched the lab's official lookup, and its comparison catalog is broad. This supports a COA-Verified status.

The main limits are a young domain, limited independent reputation outside Trustpilot, limited public legal-identity and street-address disclosure, variable test-panel breadth, some older COA dates, final sales, and inconsistent damage-reporting windows. PeptidePrices completed direct private owner diligence without publishing the requested details. Match every report to the exact product, strength, batch, date, and panel. Use code peptideprices for 10% off; it auto-applies through the referral link.

Verification notes

What we reviewed, with the limits of that evidence kept explicit.

01

Company & checkout

Lost Coast Aminos is a California research-material storefront. Its public site provides sales, support, and information email addresses, along with shipping, return, and research-use policies. Its Trustpilot contact address and repeated customer references identify Bill as the owner and support contact. The reviewed pages do not publish Bill's surname, a legal entity, or a street address. The domain was registered on October 21, 2025.

02

COA review

The live WooCommerce catalog listed 55 products on August 20, 2026. PeptidePrices added 50 unique comparison-ready product and strength offers. We excluded skincare, bacteriostatic water, Adamax, one liquid GHK-Cu presentation, and unsupported or ambiguous products and blends. Canonical comparison keys remain Semaglutide, Tirzepatide, and Retatrutide, while the Lost Coast stock table shows the storefront labels LCA-SM, LCA-T2, and LCA-R3 beside those identities.

03

Reputation & rating context

Lost Coast publishes a public batch-linked report gallery from Kovera Labs, BT Labs/BioTools, and Freedom Diagnostics. PeptidePrices inspected and confirmed Kovera records KVR-2026-F286CE for SLU-PP-332 10mg batch LCA-07172026SLU10 and KVR-2026-5F6994 for Cagrilintide 5mg batch LCA0526CGL5. Both list identity, purity, measured content, endotoxin, sterility, heavy metals, and three-vial conformity. A sampled BT Labs BPC-157 20mg report lists identity, 99.8% purity, and 20.4mg potency, but excludes microbial and endotoxin testing. Some gallery records predate the newest catalog lots; match each report to the exact compound, strength, batch, date, and panel.

04

Evidence note

Lost Coast states that paid orders normally process in one to three business days. Checkout accepts major credit and debit cards, Zelle, and Cash App. It showed optional $3 shipping protection and $15 FedEx two-day delivery, and the peptideprices reader coupon auto-applies through the referral link. The dedicated return policy makes sales final and asks customers to report damaged, defective, or incorrect items within 24 hours. Other site terms use 48 hours, so the published windows are inconsistent. Shipping destinations beyond the United States were not verified.

05

Evidence note

Trustpilot listed 4.7/5 from 36 exact-domain reviews during this review. Trustpilot exposed 32 individual review permalinks; PeptidePrices indexed every readable review on the community page as a short attributed paraphrase, and the vendor publicly replied to 23 of those 32 records. The wider exact-domain independent footprint remains limited. PeptidePrices also completed direct private owner diligence, which materially strengthened the transparency assessment without publishing the requested private details. The owner-informed evidence score is 9.5/10 after nearest-half rounding of the 9.3 weighted result: COA 10, reputation 8.5, transparency 9, and operations 9. Affiliate status does not affect the score. The exact lowercase code peptideprices gives 10% off and auto-applies through the referral link.

Limited exact-domain footprint outside Trustpilot

$3 protection; $15 FedEx two-day option

Checkout showed optional shipping protection, FedEx two-day delivery, major-card payment, and automatic coupon application. Published damage windows still conflict between 24 and 48 hours. These disclosures are not customer-review evidence.
