Peptide classes
The family is grouped by which receptors a molecule activates, not by brand or indication. That is the only grouping that predicts how a peptide behaves.
GLP-1
5 ENTRIESSingle-receptor incretin agonists — the approved backbone of the class.
GLP-2
2 ENTRIESIntestinotrophic analogues acting on the GLP-2 receptor.
GLP-3
4 ENTRIESThe consumer nickname for triple agonists led by retatrutide.
Dual agonist
1 ENTRIESGIP + GLP-1 co-agonists combining two incretin pathways.
Amylin
1 ENTRIESAmylin analogues used alone or paired with an incretin.
Native hormones
3 ENTRIESThe endogenous peptides the whole class is modelled on.
GH secretagogues
6 ENTRIESGHRH analogues and ghrelin-receptor agonists that raise endogenous growth hormone.
Repair & recovery
3 ENTRIESPeptides studied for tissue healing, angiogenesis and connective-tissue repair.
Immune & inflammation
2 ENTRIESThymic and anti-inflammatory peptides that modulate immune signalling.
Melanocortin
2 ENTRIESMelanocortin-receptor agonists affecting pigmentation, arousal and appetite.
Longevity & metabolic
3 ENTRIESMitochondrial and pineal peptides studied in ageing and metabolic research.
Neuro & cognitive
2 ENTRIESRegulatory peptides studied for anxiety, stress resilience and cognition.
