Overview
Research areas.
Peptides grouped by their primary research context. A peptide can be assigned to several areas. The assignment is based on the focus of the available literature, not on clinical approval.
Muscle growth
GH axis, protein synthesis, body composition
Peptides investigated in preclinical and early clinical studies in the context of growth hormone secretion, muscle mass and body composition. Predominantly GH secretagogues from the GHRH and GHRP classes.
Recovery
Tissue, tendons, wound healing
Substances investigated in animal models and early clinical studies for tissue-regenerating, wound-healing or gastroprotective properties.
Anti-aging
Longevity, telomeres, mitochondrial health
Peptides at the focus of longevity research. They address telomerase activity, mitochondrial function or endocrine age-related changes. Evidence predominantly preclinical.
Cognition
Neuroprotective, focus, memory
Peptides acting on CNS transmitter systems, BDNF expression or neuroprotective mechanisms. Predominantly from Russian peptide research. Western GCP studies are lacking.
Metabolism
Insulin sensitivity, body weight, GLP-1 axis
Incretins, GLP-1 agonists and GH fragments investigated in the context of type 2 diabetes, obesity and metabolic syndrome. Includes both approved medicines and experimental substances.
Libido
Melanocortin system, sexual health
Melanocortin receptor agonists acting centrally on sexual behaviour and erectile mechanisms. Includes FDA-approved (PT-141) and unapproved (Melanotan II) substances.
Skin & hair
Collagen, melanin, skin care
Peptides with effects on skin pigmentation, collagen synthesis or hair follicles. GHK-Cu is legally available as a cosmetic ingredient; other substances in this group are not approved.
Immunomodulation
Immune regulation, inflammation, cytokine balance
Peptides that have shown immunomodulatory or inflammation-modulating effects in preclinical studies. Includes thymosin derivatives and tuftsin analogs.
