A number of research peptides are referenced in the scientific literature on metabolic and energy regulation. This overview introduces the main classes as research tools. It is written for qualified researchers, describes in-vitro and preclinical research context only, and makes no therapeutic or human-use claims.
Incretin receptor agonists
The incretin hormones GLP-1 and GIP are studied for their roles in glucose and appetite signalling. Research peptides in this class include single, dual and triple receptor agonists – for example Tirzepatide (a dual GIP/GLP-1 agonist) and Retatrutide (studied as a triple GIP/GLP-1/glucagon agonist). They are widely referenced in metabolic-signalling research models.
Amylin analogs
Amylin is a hormone studied alongside the incretins in appetite- and satiety-regulation research. Cagrilintide is a long-acting amylin analog referenced in this area.
Mitochondrial and GH-axis compounds
MOTS-c, a mitochondrial-derived peptide, is investigated in cellular-energy and metabolic-regulation research, while the GHRH analog Tesamorelin is referenced in adipose-tissue and metabolic studies.
You can browse these together on our metabolic research peptides collection. Every compound is third-party tested with a certificate of analysis and is supplied strictly for in-vitro laboratory research – not for human or animal consumption.
