Peptides Encyclopedia

A fragment of human growth hormone (177–191) that mimics the lipolytic effect of hGH without impacting blood glucose or IGF-1 levels. Studied for fat metabolism in animal models.

An 11-amino-acid peptide derived from erythropoietin that selectively activates the innate repair receptor (IRR). Researched for tissue repair and neuropathy.

A 15-amino-acid partial sequence of human gastric juice protein BPC. Investigated for tendon, ligament, and gut-barrier healing in animal studies.

A long-acting amylin analogue that slows gastric emptying and promotes satiety. Often researched alongside GLP-1 agonists for synergistic metabolic effects.

A modified growth hormone-releasing hormone (GHRH) with a DAC (drug affinity complex) that extends half-life. Stimulates pulsatile GH release.

A small peptide activator of hepatocyte growth factor (HGF) with high oral bioavailability. Studied for synaptogenesis and neurorestoration.

A synthetic version of epithalamin that activates telomerase. Investigated for circadian regulation and cellular senescence markers.

A tripeptide-copper complex that modulates collagen synthesis and tissue remodeling. Used in skin and wound-healing research.

A synthetic ghrelin mimetic that stimulates GH secretion via the ghrelin receptor. Shorter half-life than GHRP-6 with less appetite stimulation.

A potent hexapeptide GH secretagogue with strong cardioprotective effects in animal models via CD36 activation.

Recombinant somatropin with the native 191-amino-acid sequence. Reference standard for comparing GH secretagogue efficacy.

A 24-amino-acid mitochondrial peptide that inhibits apoptosis and reduces oxidative stress. Studied for neuroprotection and metabolic regulation.

A selective GHRP-receptor agonist that stimulates GH without significantly raising cortisol or prolactin. Preferred for cleaner GH pulses.

A hypothalamic neuropeptide that triggers GnRH secretion via GPR54. Studied for HPG axis activation and reproductive hormone research.

A tripeptide fragment of alpha-MSH with potent anti-inflammatory and antimicrobial properties. Researched for gut and skin inflammation.

The only known human cathelicidin, a 37-residue peptide with broad antimicrobial and immunomodulatory activity.

A synthetic melanocortin analog that activates MC1R and MC4R. Used in tanning and sexual-dysfunction research contexts.

A 16-amino-acid mitochondrial peptide that improves insulin sensitivity and metabolic homeostasis through AMPK activation.

A coenzyme central to cellular redox reactions and sirtuin activation. Declines with age; supplementation studied for metabolic and neurovascular health.

A posterior pituitary neuropeptide involved in social bonding, stress modulation, and smooth-muscle contraction. Investigated for anxiety and reproductive research.

A cyclic heptapeptide melanocortin agonist targeting MC4R. Studied for sexual arousal and energy-balance research.

A triple agonist of GLP-1, GIP, and glucagon receptors. Studied for potent glycemic control and weight reduction in metabolic research.

A long-acting GLP-1 analog with 94% homology to native GLP-1 and a fatty-acid side chain for albumin binding. Standard reference for incretin research.

A synthetic ACTH fragment with nootropic and neuroprotective properties. Investigated for BDNF/NGF upregulation and cognitive repair.

The first 29 amino acids of GHRH that stimulates pituitary GH release. Used as a diagnostic and research reference for GH deficiency.

A potent MC4R-selective agonist studied for genetic obesity and energy-homeostasis disorders.

A synthetic tuftsin derivative with anxiolytic and nootropic effects. Researched for modulation of enkephalinase and immune response.

The active 43-amino-acid fragment of thymosin beta-4. Promotes actin polymerization, cell migration, and wound healing in research models.

A synthetic GHRH analog that preferentially reduces visceral adiposity. Used in HIV-associated lipodystrophy and metabolic research.

A thymic peptide complex that regulates T-cell maturation and immune homeostasis. Studied for immunosenescence.

A 28-amino-acid thymic peptide that modulates immune response via Toll-like receptors. Researched for immune restoration and viral response.

A dual glucose-dependent insulinotropic polypeptide and GLP-1 receptor agonist. Studied for superior glycemic control and weight reduction.

A 28-amino-acid neuropeptide with potent vasodilatory, anti-inflammatory, and immunomodulatory properties. Researched for mast-cell and neuroprotection studies.
