About QYAOBIO 强耀生物
ChinaPeptides Co., Ltd. — peptide synthesis in Shanghai since 2008. Empowering life sciences with precision.
Company Profile
QYAOBIO (强耀生物) is the brand of ChinaPeptides Co., Ltd., founded in 2008 in Shanghai by Mr. Xiping Wang. Eighteen years on, peptide chemistry is still the whole of what we do: solid-phase synthesis, purification, modification and analysis, all under one roof.
We are ISO 9001 certified and hold 20+ patents in China. Our chemists work from a library of 400+ peptide synthesis and modification methods — the core technology behind everything we ship, from a milligram of a simple linear sequence to kilogram-scale production of a complex cyclic or stapled peptide.
Our mission has not changed since day one: providing innovative products in support of the scientific community.
Two Doors, One Company
QYAOBIO runs two websites, and there is a compliance reason for it: Chinese ISO and GMP rules require a domestic manufacturer to maintain a separate corporate registration site, distinct from where it sells. This storefront ships worldwide and handles every order from outside mainland China — personal or business. The corporate site serves mainland China only. Same company, same chemists, same building — two different ways in:
qyaobiopeptides.com — you are here
Our direct research storefront, open to individual researchers and business buyers alike, shipping worldwide. Real catalog, listed prices, cart and checkout — order 1 vial or 100. No account application, no minimum, no sales gate. Wholesale tiers and volume pricing are available on this site too. Every order from outside mainland China is placed here — personal or business, single vial or bulk / wholesale / OEM.
Browse the Catalogwww.qyaobio.com — inside mainland China only
Our Chinese corporate registration site, serving mainland China only — the one Chinese ISO and GMP rules oblige a domestic manufacturer to keep separate from its storefront. It ships within China only, and only to buyers holding the Chinese licences required to receive these compounds. It is not a shop and has no checkout. Go there for Chinese business registration and company records, ISO/GMP documentation or a domestic supplier account.
Visit qyaobio.comIn short: buy here, register there. Buying for research? You're in the right place — order directly here; everything you need is on this site.
