Acetyl tetrapeptide-5
is used in cosmetic eye formulations to decrease puffiness, eye bags, and dark circles by reducing edema and protecting proteins such as SOD from glycation
Alanine
Ala / A · hydrophobic residue · neutral charge
AOD-9604
is studied as an anti-obesity peptide that can reduce weight gain and increase fat oxidation in obese animal models with generally neutral effects on IGF-1 and glucose metabolism in early human trials
Arginine
Arg / R · basic residue · positive charge
Argireline
is a topical cosmetic peptide reported to decrease dynamic wrinkles by partially mimicking the mechanism of botulinum toxin in a non-invasive manner
Asparagine
Asn / N · polar residue · neutral charge
Aspartic acid
Asp / D · acidic residue · negative charge
BPC-157
is investigated for accelerating healing of gastrointestinal mucosa, tendons, ligaments, bone, and nervous tissue in preclinical models, with anti-inflammatory and pro-angiogenic effects
Comparison
While Humanin exerts neuroprotective and cytoprotective effects in models of Alzheimer’s disease, ischemia, and metabolic stress, reducing apoptosis and improving cell survival7136141, KPV is investigated as an anti-inflammatory and barrier-protective agent in skin and mucosal models, reducing pro-inflammatory cytokines and promoting tissue repair684.
While Humanin works as a mitochondrial-derived 24-amino-acid peptide that protects cells against diverse apoptotic insults by interacting with cell-surface cytokine receptor complexes and intracellular targets, thereby activating pro-survival STAT3 and other pathways7136141, KPV is the C-terminal Lys-Pro-Val tripeptide fragment of α-MSH, which exerts potent anti-inflammatory effects largely via inhibition of NF-κB signaling and modulation of cytokine expression, with many actions independent of classical melanocortin receptor activation684.

The clearest overlap between Humanin and KPV is that both converge around Signaling modulator. Their typical research and application settings separate fairly clearly: Humanin is more often discussed in the realm of Neurology and brain health, Aging and longevity, and Cardiovascular health, whereas KPV is more often associated with the realm of Immunology and inflammation, Gastroenterology, and Dermatology and aesthetics. Both appear to work through Signaling modulator, but the functional emphasis still separates, with Humanin leaning toward Neuroprotection and cognition and Mitochondrial function modulation and KPV leaning toward Immune regulation. Humanin has a more mitochondrial-encoded origin, while KPV is closer to natural endogenous background and both are still best understood as being in Preclinical development. Their sequence patterns also diverge, with Humanin showing alpha-helical domain features and KPV showing protein-mimetic sequence features.
