Frequently asked questions
QYAOBIO (强耀生物), also written QYAOBIO Peptides, is the brand of ChinaPeptides Co., Ltd., founded in 2008 and headquartered in the Pudong New Area of Shanghai, with a subsidiary in Suzhou and an R&D centre in Ezhou. We have 18 years of peptide synthesis experience, are ISO 9001 certified, and hold more than 20 patents in China. Our work spans three pillars — peptides, recombinant proteins and antibodies. This site, qyaobiopeptides.com, is our direct storefront for research compounds.
qyaobiopeptides.com (this site) is the shop. Anyone — individual researcher or business — can buy catalogue research compounds here directly: public prices, add to cart, check out, shipped with tracking. No account, no approval, no minimum order.
www.qyaobio.com is our corporate site — not another shop. ISO and GMP standards require a Chinese manufacturer to maintain a separate corporate registration site, and that is what qyaobio.com is: business registration and company records, antibody & protein services, and bulk / OEM enquiries. It carries no cart, no retail prices and no checkout. If you want to buy something we already make, stay here.
No. This storefront is open to everyone. There is no business verification, no purchase-order process and no minimum order value — you can buy a single vial. Businesses are equally welcome and benefit from automatic volume discounts at checkout; if you also want a formal supplier account, that is handled on qyaobio.com — the separate corporate registration site ISO and GMP standards require us to keep.

We accept Visa, Mastercard, Apple Pay, Google Pay, Revolut and bank transfer through a secure, PCI-compliant payment processor — you pay the exact amount shown, charged like any normal online purchase, and we never store your card details. We also accept cryptocurrency (BTC, ETH, USDT, USDC, SOL, XRP, BNB) with 10% off your order.
Our synthesis runs at a >95% success rate with purity specified per project — from crude up to 98% — and we work sequences up to 150 amino acids using over 400 modification methods.

We are ISO 9001 certified.
