Peptide Class Guides
Comprehensive guides to major peptide classes, covering shared mechanisms, clinical landscapes, and the individual compounds within each therapeutic family.
GLP-1 Receptor Agonists & Incretin Mimetics
Glucagon-like peptide-1 (GLP-1) receptor agonists are a class of peptides and small molecules that mimic the incretin hormone GLP-1, which is secreted by intestinal L-cells in response to nutrient ing...
Growth Hormone Secretagogues (GHRP & GHRH)
Growth hormone secretagogues (GHS) are a class of peptides that stimulate the pituitary gland to release endogenous growth hormone (GH). The class is divided into two mechanistic subgroups: growth hor...
BPC Family & Tissue Repair Peptides
The BPC family and tissue repair peptide class encompasses endogenous and synthetic peptide sequences that promote healing of musculoskeletal structures, skin, mucosa, and neural tissue through mechan...
Thymosin Family & Immune-Modulating Peptides
The thymosin family encompasses thymic peptides and related immune-modulating sequences that regulate components of the innate and adaptive immune system. The class includes thymic peptides (Thymosin ...
Melanocortin Receptor Peptides (MC1R–MC5R)
Melanocortin peptides are a class of endogenous and synthetic ligands that activate the five melanocortin receptor subtypes (MC1R–MC5R). Endogenous melanocortins include alpha-MSH, beta-MSH, and ACTH,...
TRH Analogs & Neuroendocrine Regulatory Peptides
TRH analogs and neuroendocrine regulatory peptides are a class of hypothalamic and pituitary-derived sequences that regulate the major endocrine axes: thyroid (TRH), reproductive (GnRH/Kisspeptin), an...
Nootropic & Neurotropic Peptides
Nootropic peptides are a loosely defined class of peptide sequences investigated for effects on cognition, anxiety, and neuronal survival. The class spans ACTH-derived fragments (Semax), immunomodulat...
Mitochondrial & Longevity-Targeted Peptides
Mitochondrial peptides represent a distinct frontier in peptide pharmacology: rather than targeting cell-surface receptors, these compounds act on the organelle that governs cellular energy production...
Gut Health & Mucosal Repair Peptides
Gastrointestinal peptides are a class defined by their site of action: the gut lumen, mucosa, and enteric signaling systems. The class spans gastric-juice-derived sequences with unusual stability in t...
