Peptide classes

Compounds grouped by what they actually do at the receptor, not by what they are marketed for. 15 classes covering 87 compounds.

Bioregulators 16

The Khavinson short peptide series, each associated with a specific tissue. Evidence comes largely from one research group.

Agonists at the growth hormone secretagogue receptor, the target of endogenous ghrelin.

Compounds studied for soft tissue, gastrointestinal and wound repair. The highest-traffic and highest-scrutiny group.

Peptides studied for cognition, anxiety, sleep and neuroprotection.

Incretin receptor agonists for glycaemic control and weight management, including the dual and triple agonists.

Insulin-like growth factor analogs, splice variants and growth hormone fragments.

Topically applied peptides for skin ageing, pigmentation and expression lines.

Growth-hormone-releasing hormone analogs that act on pituitary somatotrophs to stimulate endogenous GH release.

Mitochondria-derived peptides and compounds targeting cellular ageing.

Compounds acting on the hypothalamic-pituitary-gonadal axis, including TRT adjuncts.

Compounds targeting adipose tissue and energy metabolism outside the incretin pathway.

Compounds that do not fall cleanly into the other classes.
