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, Tirzepatide is approved for type 2 diabetes and obesity, producing larger HbA1c and body-weight reductions than semaglutide in head-to-head trials24.
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, Tirzepatide is a 39-amino-acid synthetic peptide primarily based on GIP sequence with C20 fatty diacid conjugation that acts as a dual agonist at GIP and GLP-1 receptors, enhancing glucose-dependent insulin secretion, suppressing glucagon, delaying gastric emptying, and reducing appetite24.

Not assigned in the current dataset.
Humanin and Tirzepatide are noticeably different, with limited direct overlap in their usual biological context. Both are often discussed in Cardiovascular health contexts, while Humanin is more of a mitochondrial peptide and Neuropeptide and Tirzepatide is better described as a metabolic peptide and Hormone peptide. They also influence different molecular systems, with Humanin tracking more closely to GPCR receptor while Tirzepatide centers more on GLP-1 receptor. Humanin has a more mitochondrial-encoded origin, while Tirzepatide is closer to synthetic analog background and their development context also differs, with Humanin in Preclinical development while Tirzepatide is approved. Humanin takes the form of a linear peptide, whereas Tirzepatide is closer to a peptide conjugate, while Tirzepatide incorporates lipidation and d-amino acid substitution features that are not part of Humanin.
