Featured peptides
LY3437943
An investigational triple agonist peptide acting at the GIP, GLP-1 and glucagon receptors. It is one of the most closely watched compounds in metabolic research because of the magnitude of body-weight change reported in published phase 2 trials.
LY3298176
A dual GIP and GLP-1 receptor agonist that has been evaluated across a large published clinical programme in type 2 diabetes and in weight management, with well-characterised pharmacokinetics and a documented stepwise escalation schedule.
Body Protection Compound
A synthetic pentadecapeptide derived from a sequence identified in human gastric juice. It is one of the most widely studied peptides in preclinical tissue-repair research, though human clinical data remains very limited.
Thymosin Beta-4 fragment
A synthetic fragment related to thymosin beta-4, a naturally occurring actin-sequestering protein. Research focuses on cell migration, angiogenesis and soft-tissue repair, with a substantial veterinary literature.
Mitochondrial-derived peptide
A 16-amino-acid mitochondrial-derived peptide encoded in mitochondrial DNA. Research interest centres on metabolic regulation, exercise physiology and biological ageing.
alpha-MSH fragment
A tripeptide corresponding to the C-terminal sequence of alpha-melanocyte-stimulating hormone. It is studied for anti-inflammatory activity without the pigmentation effects associated with the parent hormone.
Nicotinamide adenine dinucleotide
A coenzyme present in every living cell and central to energy metabolism and DNA repair. Although not a peptide, NAD+ appears throughout longevity research and is commonly catalogued alongside research peptides.
GSH
A tripeptide antioxidant synthesised in every cell, central to redox balance and detoxification. It is one of the most extensively characterised endogenous peptides in biochemistry.
Copper peptide
A naturally occurring copper-binding tripeptide found in human plasma. It is among the best characterised peptides in dermatological and wound-healing research.
Elamipretide
A mitochondria-targeted tetrapeptide that binds cardiolipin on the inner mitochondrial membrane. It has progressed further into human clinical evaluation than most research peptides in the longevity space.

PepDex sells nothing and recommends nothing. Every page summarises what has been published, states the type of evidence behind it, and links to the source. Where human data does not exist, we say so.
