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 Argireline is a topical cosmetic peptide reported to decrease dynamic wrinkles by partially mimicking the mechanism of botulinum toxin in a non-invasive manner49, Exenatide is used for type 2 diabetes treatment to improve glycemic control and modestly reduce body weight through GLP-1–like insulinotropic and glucagonostatic effects6768.
While Argireline works as acetyl hexapeptide-8 (Ac-Glu-Glu-Met-Gln-Arg-Arg-NH2), a SNAP-25–mimetic peptide that competitively inhibits SNARE complex assembly, reducing acetylcholine release at neuromuscular junctions and attenuating facial muscle contraction4959, Exenatide is a 39-amino-acid exendin-4 peptide originally isolated from Gila monster venom that acts as a long-acting GLP-1 receptor agonist resistant to DPP-4 degradation67.

Argireline and Exenatide are noticeably different, with limited direct overlap in their usual biological context. Their typical research and application settings separate fairly clearly: Argireline is more often discussed in the realm of Dermatology and aesthetics, whereas Exenatide is more often associated with the realm of Metabolic and endocrine. They also influence different molecular systems, with Argireline tracking more closely to SNARE complex while Exenatide centers more on GLP-1 receptor. Argireline has a more synthetic design origin, while Exenatide is closer to venom-derived background and their development context also differs, with Argireline cosmetic grade while Exenatide is approved. Argireline carries acetylation features, while Exenatide instead reflects amidation changes, while their sequence patterns also diverge, with Argireline showing protein-mimetic sequence features and Exenatide showing alpha-helical domain features.
