Frequently Asked Questions

No. All PeptideLab products are strictly for in-vitro research and laboratory use only. They are not approved for human or veterinary administration and must not be used as drugs, supplements, or therapeutic agents. Our products are sold exclusively to qualified researchers.

Research grade means our compounds meet stringent purity standards (≥98%) suitable for laboratory experimentation. This is different from pharmaceutical or clinical grade, which requires FDA approval and additional regulatory compliance.

Lyophilized (freeze-dried) peptides should be stored at -20°C and kept away from moisture and light. Once reconstituted, store at 4°C and use within 7–14 days depending on the compound. Always refer to the CoA for compound-specific storage guidance.

We ship to most countries worldwide. However, it is the buyer's sole responsibility to determine whether importation of specific peptide compounds is legal in their country. PeptideLab is not liable for customs seizures or legal consequences arising from importation.
