What are peptides and how do they work?
Peptides are short chains of amino acids that occur naturally in organisms, where they act as messengers in many biological systems. While some peptides have been developed for medical use, laboratory research focuses on understanding their activity at the cellular level, examining how they impact essential processes in vitro.
Products from Zenara Peptides do not include usage instructions, as they are strictly for in vitro research and prohibited by law for human or animal use. Misuse or unlawful application will result in permanent denial of service.
Orders are typically processed and shipped within 24 hours on weekdays. Delivery times vary by location, but most domestic orders arrive within 3–5 business days. You’ll receive tracking information as soon as your order ships.
Each vial contains exactly what’s shown on the label. For example, a 10mg vial has exactly 10mg of lyophilized peptide. Researchers can divide it into smaller portions—like four 2.5mg measurements—but the total amount remains 10mg.
Peptides are supplied as lyophilized powder. They do not come reconstituted, and any extra supplies must be sourced separately for research applications.
In lyophilized powder form, peptides stay stable for up to 2 years. After reconstitution, it should be refrigerated and is generally stable for up to 2 months.
