04Why Zhicheng Bio
Built for repeat bulk buyers
We optimize for the things procurement teams actually measure: stock depth, honest lead times, complete paperwork and a counterpart who answers.
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.
