- Transit & cold-chain
- Lyophilized peptides are stable through standard ground transit and are packed to protect the product; temperature-sensitive items are packed accordingly. Refrigerate or freeze on arrival.
- Storage
- Store as labeled. Keep lyophilized material sealed, cold (typically −20 °C), and away from light and moisture; reconstituted solutions are less stable — refrigerate and use promptly. Requirements vary by compound, so follow the label and Certificate of Analysis.
- Returns & reship
- Research compounds are final-sale, but anything that arrives damaged or incorrect is replaced or refunded — email us within 7 days with photos. Returns & refunds →
