Introduction
When ambient express is acceptable vs when cold chain matters for peptides shipped from China.
Peptide From China publishes independent third-party buyer guides for international laboratories sourcing research peptides from China. This is not manufacturer advertising—we help buyers understand supply chain risk before placing orders.
Lyophilized Stability Basics
Most catalog peptides ship lyophilized with good ambient stability for short express lanes.
When to Add Cold Packs
Methionine-rich, cysteine-rich, or supplier-flagged sequences may need enhanced temperature control.
On Receipt
Inspect cake integrity; store at -20°C for long-term retention.
