What is ipamorelin?
Ipamorelin is a synthetic pentapeptide in the growth hormone secretagogue class, supplied for laboratory research. The material is produced by solid-phase peptide synthesis and supplied as a lyophilised powder.
Ipamorelin is classified as a research chemical and is supplied strictly for in-vitro laboratory research.
Ipamorelin in the research literature
Ipamorelin appears in the laboratory literature in receptor-binding and signalling studies, typically in in-vitro models. Index Peptides lists it as a technical research material only and takes no position on any application.
Form, handling and storage
Ipamorelin is supplied as a lyophilised (freeze-dried) powder in a sealed vial. Lyophilised peptides are best stored at -20°C, desiccated and protected from light; long-term stability data are batch-specific and recorded against the batch record.
Batch documentation at Index Peptides
Review the published certificate for the exact lot, including the laboratory, report date and analytical results actually reported. HPLC purity alone does not confirm LC-MS identity. Contact us before ordering if a required result is not published.
Frequently asked questions
Who is ipamorelin supplied to?
Index Peptides supplies ipamorelin exclusively to qualified researchers and licensed laboratories, for in-vitro research only. It is not for human or veterinary use.
What is the CAS number for ipamorelin?
170851-70-4, with a molecular weight of approximately 711.9 g/mol.
How is each batch verified?
Each published batch record shows the reversed-phase HPLC purity result and states when no LC-MS identity result has been published. Records are linked from the product page, and any batch can be checked by lot number on the verify page.
What is the shelf life of Ipamorelin?
As supplied (lyophilised powder in a sealed vial), Ipamorelin is stored at -20C, desiccated and protected from light. Long-term stability is documented per batch on the certificate of analysis; treat the batch record as the authoritative shelf-life reference for that lot.
What is the difference between the sizes?
The difference is the nominal peptide content per vial. Ipamorelin is supplied as 5mg vials. Every format carries the same batch documentation and purity testing.
What does the certificate of analysis show?
Review the published certificate for the exact lot, including the laboratory, report date and analytical results actually reported. HPLC purity alone does not confirm LC-MS identity. Contact us before ordering if a required result is not published.
