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, Retatrutide is an investigational agent that produces very large body-weight reductions in early trials by simultaneously engaging GLP-1R, GIPR, and GCGR to enhance satiety, energy expenditure, and glycemic control2575.
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, Retatrutide is a triple incretin agonist peptide derived from a GIP backbone and engineered to activate GLP-1, GIP, and glucagon receptors, with non-natural residues and fatty-acid conjugation that confer long half-life and balanced multi-receptor signaling256575.

Humanin and Retatrutide are noticeably different, with limited direct overlap in their usual biological context. 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 Retatrutide is more often associated with the realm of Metabolic and endocrine. They also influence different molecular systems, with Humanin tracking more closely to GPCR receptor while Retatrutide centers more on GLP-1 receptor. Humanin has a more mitochondrial-encoded origin, while Retatrutide is closer to synthetic analog background with Humanin in Preclinical development and Retatrutide in Clinical phase 3. Humanin takes the form of a linear peptide, whereas Retatrutide is closer to a peptide conjugate, while Retatrutide incorporates lipidation features that are not part of Humanin.
