How we read this shop
https://hzyckswkj.en.alibaba.com/ (captcha-blocked)
notes mention “Alibaba”
Only web presence is the Alibaba.com store 'Hangzhou Yichenkang Biotechnology Co., Ltd.' (hzyckswkj.en.alibaba.com). index.html, in_ID/index.html, productlist.html and the m. mobile store all serve Alibaba's slider captcha ('Please drag the slider to verify') to headless Chromium (2026-10-07), so no listing or price can be read; Alibaba prices would be wholesale/MOQ anyway (search snippets only show a cosmetic Alpha Arbutin powder at $60-85/kg). The e-mail domain Finnrick lists (sales@peptide-china.com) belongs to a Chinese peptide API manufacturer's corporate site with no shop. Order via Alibaba inquiry/Trade Assurance or WhatsApp +86 138 5857 2599 / +86 199 0663 3110. Returns [].
