ZHICHENG BIO
A Shanghai supply partner focused on one category
Straight-to-source ingredient supply
Zhicheng Biotechnology Co., Ltd. is a Shanghai-based exporter specializing in amino acids and sports-nutrition raw ingredients, built on a team with 30 years in the amino acid trade. We concentrate on a tight catalog we know deeply — sourcing each product line at the source, holding multi-tonne inventory on the SKUs our customers reorder most, and consolidating shipments efficiently out of Shanghai.
Buying through layers of resellers adds cost and blurs accountability. Our model is simpler: long-term sourcing relationships on one side, documented batches and honest lead times on the other. Every quotation comes with the spec sheet and a recent batch COA, so your QA team can evaluate before you commit.
Our customers are supplement brands, contract manufacturers and ingredient distributors worldwide who need dependable specs, honest lead times and responsive communication — not a thousand-item catalog. Quotes are turned around quickly, in English or Chinese, with export terms tailored to your route.

From source to your port
Sourcing partners
Long-term manufacturer relationships across China for each product line — sourced at origin, not through resellers.
Shanghai HQ & consolidation

Global delivery
FOB Shanghai, CIF or DDP lanes to North America, Europe, Southeast Asia, the Middle East, ANZ and beyond.
What procurement teams actually measure
US warehouse in Los Angeles
28 actives held in the US — NAD+ precursors, fisetin, dihydromyricetin, ergothioneine, creatine and more. Domestic delivery, no import clearance on your side, and trial quantities that actually make sense. See the stock list.
Bulk ready stock
Multi-tonne inventory held on core SKUs — glutamine, citrulline, taurine, carnitine tartrate and more — so large orders don't wait on production slots.
Honest lead times
In-stock items ship immediately. Non-stock items typically reach Shanghai port in about one week — and we tell you upfront when they won't.
Documentation-first
COA, Spec Sheet and MSDS per batch. Third-party lab verification available pre-shipment. Paperwork travels with every order — not after it.
Flexible packing
Standard 25 kg bags, cartons or drums — with private packing and labeling arrangements available for regular customers.
