Peptide Categories
21 categories organized by biological function and therapeutic application. Each category contains detailed profiles of related peptides.
Growth Hormone Secretagogues
Peptides that stimulate the pituitary gland to release growth hormone, either by mimicking GHRH (GHRH analogs) or by acting on ghrelin receptors (GHRPs).
Healing & Recovery
Peptides studied for tissue repair, wound healing, gut protection, and accelerated recovery from injury.
Sexual Health
Peptides that influence sexual arousal, libido, and reproductive function via central nervous system pathways.
Cognitive & Nootropic
Peptides investigated for memory enhancement, focus, neuroprotection, and cognitive performance.
Anti-Aging & Longevity
Peptides with potential telomere-protective, senolytic, or cellular rejuvenation properties.
Weight Loss & Metabolic
Peptides studied for fat oxidation, appetite regulation, insulin sensitivity, and body composition.
Immune Support
Peptides that modulate T-cell activity, cytokine production, and innate or adaptive immunity.
Skin & Hair
Peptides researched for collagen synthesis, wound healing, skin rejuvenation, and hair follicle health.
Muscle Growth
Peptides that promote myogenesis, satellite cell activation, anti-atrophy signaling, or myostatin inhibition.
Sleep
Peptides studied for sleep quality improvement, circadian rhythm regulation, and stress-induced sleep disturbance.
Pain & Inflammation
Peptides with anti-inflammatory, analgesic, or immune-modulating properties relevant to pain management.
Mitochondrial
Peptides that target mitochondrial function, energy production, cardiolipin integrity, or mitochondrial-nuclear signaling.
Antimicrobial
Cationic peptides with broad-spectrum antibacterial, antifungal, and antiviral activity through membrane disruption.
Neuroprotective
Peptides studied for protection against neurodegeneration, excitotoxicity, and age-related cognitive decline.
Reproductive & Fertility
Peptides that regulate the hypothalamic-pituitary-gonadal axis, gonadotropin secretion, and reproductive function.
Cardiovascular
Peptides with direct cardiovascular effects including natriuretic peptides, vasodilators, and cardioprotective agents.
Gastrointestinal
Peptides regulating GI motility, secretion, appetite, and gut-brain signaling.
Bone & Mineral Metabolism
Peptides regulating bone formation, calcium homeostasis, and mineral metabolism.
Antiviral
Peptides that inhibit viral entry, replication, or immune evasion.
Related Compounds
Non-peptide or next-generation compounds frequently discussed alongside peptides including GLP-1 agonists, dual/triple agonists, and metabolic agents.
SARMs & Androgen Modulators
Selective Androgen Receptor Modulators (SARMs) and related compounds. Included for educational comparison with peptide therapies.
