Overview#

China Peptides (QYAOBIO / Qiangyao) is a Shanghai-based custom peptide, antibody, and protein synthesis company founded in 2008 per the vendor (domain chinapeptides.com registered 2008-10-28), selling made-to-order research-grade peptides (crude to 98% purity, mg to multi-kg, 400+ modifications) directly to researchers worldwide in its own name via its own Chinese and English sites — online order application and email quotation, no retail checkout, no published prices, payment methods, refund policy, or shipping rates. GATE: PASS on the direct-sales prong only — no U.S. legal entity, office, address, or phone was found in any source, but U.S. buyers can and do order directly from the vendor (documented example: Yale University, New Haven, CT, researchers listing peptides synthesized by ChinaPeptides Co., Ltd., Shanghai), and no independent-U.S.-distributor-only pattern was found. Regulatory record: all defined searches (FDA warning letters, recalls, import alerts, FTC, state AG, civil litigation, criminal/injunctive) returned No Record Found for THIS vendor; the 2012 FDA warning letter and 2026 House committee letter naming 'Chinese Peptide Company' of Hangzhou are a different company and must never be attributed to this profile. Testing evidence is vendor-generated only: HPLC/MS reports stated to accompany syntheses, no public COA library, no named independent lab, no verification portal, no dated COA sampled. Principal gaps are corporate-registry verification (exact Chinese legal entity; Shanghai/Suzhou/Hubei Qiangyao mapping) and unpublished commercial terms. No serious findings.

Testing and COA Evidence#

Public COA AvailabilityCOAs / analytical reports are order-accompanying, not publicly posted — the Chinese site states peptides are supplied with HPLC and MS test reports ('附有HPLC和MS检测报告'), and the English site states each purified protein has a complete COA report. No public COA library, downloadable lot COA, or COA link was found on the catalog pages fetched (e.g., the ACTH catalog page lists sequence, CAS, and formula only).

Batch / Lot SpecificityNot independently verified

UnknownSource: China Peptides (Qiangyao) homepage — chinapeptides.com (Chinese)

Independent Laboratory IdentityNot independently verified

UnknownSource: China Peptides (Qiangyao) homepage — chinapeptides.com (Chinese)

COA Verification StatusNot verifiable through a public portal in this pass — no COA lookup or verification mechanism exists on chinapeptides.com or qyaobio.com on the pages fetched, and no independent index record for this vendor was found.

ModerateSource: QYAOBIO homepage — English site of ChinaPeptides Co., Ltd.

Test RecencyNot independently verified

UnknownSource: China Peptides (Qiangyao) homepage — chinapeptides.com (Chinese)

Testing CoverageVendor-stated coverage is order-wide for custom synthesis: the Chinese site states synthesized peptides are supplied with HPLC and MS reports, and the English site offers purity grades from crude to 98%, milligram to multi-kilogram quantities, and a >95% / >98% delivery success claim (vendor figures). Independent confirmation of coverage was not found — literature citations confirm U.S. and other researchers received peptides of stated purity (e.g., >95% by HPLC/MS in methods sections) but are not a coverage audit.

ModerateSource: China Peptides (Qiangyao) homepage — chinapeptides.com (Chinese)

Evidence ConsistencyClaims are internally consistent across the Chinese and English sites (founded 2008 / 18 years, Shanghai base, same lead phone 021-50795728, research-only positioning, 400+ modification methods, HPLC/MS reports). Three cautions: (1) the exact registered Chinese legal entity and the Shanghai / Suzhou / Hubei Qiangyao entity mapping are not registry-verified; (2) the name is easily conflated with Chinese Peptide Company of Hangzhou (a different vendor, with its own FDA/House correspondence) and with unrelated retail look-alike domains (chinapeptidies.com, chinapeptidesource.com) — none of that evidence was attributed here; (3) breadth claims (50,000+ customers, 50+ countries) are vendor representations, not verified counts.

Shipping & Fulfillment RepresentationsDirect worldwide fulfillment in the vendor's own name is the published model — the Chinese site claims 50,000+ global customers across 50+ countries and regions; the English site states it provides peptide, antibody, and protein synthesis service 'for researchers and scientists in worldwide' and that it cooperates directly with scientists in the biotechnology and pharmaceutical industries, in quantities from milligrams to multi-kilograms. No shipping rates, delivery times, carriers, or customs terms are published on the pages fetched; terms appear to be set per quotation.
