Frequently Asked Questions
Everything you need to know about our research compounds.
What are research peptides?
Research peptides are short chains of amino acids used by scientists and laboratories to study biological mechanisms, receptor signaling, and therapeutic pathways. They are intended strictly for in-vitro and laboratory investigation — not for human consumption.
How do I know a peptide supplier is trustworthy?
Look for HPLC and mass spectrometry verification, batch-level lab reports, transparent sourcing, and clear storage and handling guidance. Every Levels Peptides batch is tested at ≥98% purity with documentation available on request.
Are your peptides third-party tested?
Yes. Every lot we distribute is tested in an independent ISO-accredited lab by HPLC and mass spectrometry to verify identity, purity, and molecular weight before release.
How should research peptides be stored?
Lyophilized peptides are generally stored at or below 6°C, sealed, and kept away from heat, light, and moisture. Long-term storage for most compounds is -20°C or colder. Storage details for each compound are listed on the product page.
Are research peptides shipped internationally?
We currently ship within the United States. International research orders are evaluated on a case-by-case basis — please contact support for availability.
How quickly will I receive my order?
Orders placed before 12 PM EST typically ship the same business day. Domestic delivery is usually 2–5 business days via insured priority shipping.
