Metabolic Research

Metabolic research covers the signalling pathways that regulate energy balance, glucose handling and lipid metabolism — an area that has expanded considerably as incretin biology and mitochondrial signalling have become better characterised.

The compounds in this category span several mechanisms. Incretin receptor agonists such as tirzepatide and retatrutide act on the GLP-1 and GIP receptor systems, which coordinate glucose-dependent insulin release and gastric motility. Growth hormone releasing hormone analogues such as tesamorelin act further upstream on the somatotropic axis. Mitochondrial-derived peptides such as MOTS-C represent a more recently described class, encoded in mitochondrial DNA rather than the nuclear genome.

Several compounds in this category are the subject of active clinical investigation and are not approved for human use in any jurisdiction. Others are approved pharmaceuticals in some markets. Material supplied here is for laboratory research use only in either case, and the distinction between an investigational compound and an approved one is worth understanding before designing any study around it.

Every batch is assayed by an independent laboratory for identity and purity before release, with a batch-specific certificate of analysis available. Identity is confirmed by mass spectrometry and purity determined by RP-HPLC — what those figures do and don't establish is covered in our guide to peptide purity testing.

All material is supplied lyophilised. See reconstitution and storage for handling guidance.
