How we read this shop
https://www.changyuanpolypeptide.com/faq/ (what-payment-methods-do-you-accept, where-are-you-shipping-from 'largest warehouses in Hong Kong and the United States', how-long-does-it-take-to-process-and-ship-my-order); no shipping price published
Product 'Buy Now' opens a guest checkout (shop_under_order) with PAYPAL and DELIVERY_PAY payment options and Submit Order; with United States selected the delivery line is 'Fixed freight $0' (2026-10-07).
EyouCMS shop (Shenzhen, CN). Product URLs from /arcxml/1.xml (/shop/* and /product-details/*); each page's 'specification' buttons map to the embedded SpecData JSON (spec_price, spec_stock). Spec labels like '50mg*10vials' give dose and kit size: pack_qty = the '*N vials' count; specs without a vial count are taken as 1 and flagged here. Products without specs use the page price (#users_price). Prices USD. Nearly every SKU is a 10-vial kit ('Xmg*10vials'); exceptions: EPO 3000IU (no kit size stated -> pack_qty 1), Bpc157 / Tesofensine '500mcg x 100pcs' and 5-amino-1mq '50mcg x 60pcs' (pieces, form not stated). MGF and PEG MGF pages show $0 (skipped); sitemap also lists dead /shop/hgh and SLU-PP pages (404). /product-details/foxo4-dri is a second FOXO4-DRI page ($529/10x10mg) outside the product list but buyable. Shop list says 69 products. Site banner: verify seller identity with official staff before ordering (WhatsApp +852 5536 3571).
