Who operates this website
This website is operated by Guangzhou Yisheng Biotechnology Co., Ltd. through the Yisheng Peptide team.
Information we receive
When you submit a quotation form or contact us by email or WhatsApp, you may provide your name, contact details, country, customer type, company, product interests, quantities and project requirements. The website may also record the first page visited, referring page, campaign parameters, the page where a WhatsApp contact was initiated and a reference assigned to that click so we can understand which website content led to the inquiry.
How information is used
We use submitted information to respond to inquiries, prepare quotations, coordinate documentation, support orders or service projects, and evaluate which website pages contribute to relevant inquiries. A WhatsApp click is treated as a contact attempt, not proof that a message was sent.
Service providers
Form submissions and WhatsApp click references are processed by Cloudflare Workers and stored in Cloudflare D1. Form submissions are protected by Cloudflare Turnstile. WhatsApp, email providers, analytical laboratories and logistics providers operate under their own privacy terms. We do not request payment-card credentials through this website.
