Metabolic Research Peptides & Compounds

Eclipse Peptides' metabolic research category features high-purity reference compounds studied in the context of incretin and receptor signaling, including GLP-1, GIP, and glucagon receptor research. Each compound — Semaglutide, Tirzepatide, Retatrutide, and MOTS-C — is supplied as a lyophilized powder at ≥99% purity and characterized by molecular formula, CAS number, and analytical purity. All compounds in this category are third-party tested and ship with a Certificate of Analysis. These products are intended strictly for in-vitro laboratory research and are not for human or animal use.

Category FAQ.

What compounds are in the metabolic research category?+

GLP-1 receptor analogs (Semaglutide), dual GIP/GLP-1 peptides (Tirzepatide), and triple-agonist research reference compounds (Retatrutide) used in metabolic signaling studies.

What purity are these compounds?+

All compounds in this category are specified at a minimum ≥99% purity and verified by third-party HPLC and mass-spectrometry testing.

Do they ship with documentation?+

Yes. Every batch ships with a batch-specific Certificate of Analysis documenting identity, purity, and quantitative data. Safety Data Sheets are available on request.

How should these compounds be stored?+

Supplied as a lyophilized powder and stored under cold-chain-appropriate conditions (2–8°C) per each product's specification. Consult the Certificate of Analysis for reconstitution and long-term storage guidance.

What are these compounds used for?+

They are supplied strictly as reference materials for in-vitro scientific research and are not for human or animal use.
