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 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, GHRP-6 is used experimentally to produce strong GH surges and hyperphagia, allowing investigation of GH-dependent anabolism and energy-balance regulation2030.
While Exenatide works as 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, GHRP-6 is a first-generation synthetic hexapeptide ghrelin mimetic that potently stimulates GH release and markedly increases appetite via GHSR-1a activation in hypothalamus and pituitary203096.

Both peptides fall into a similar broad context as Hormone peptides, although the details of how they are used and discussed still diverge. Both are often discussed in Metabolic and endocrine contexts, while Exenatide is more of a metabolic peptide and GHRP-6 is better described as a hormone peptide. Both appear to work through Receptor agonist, but the functional emphasis still separates, with Exenatide leaning toward Metabolic regulation and GHRP-6 leaning toward Anabolic growth and Lipolysis and fat loss. Exenatide has a more venom-derived origin, while GHRP-6 is closer to synthetic design background and their development context also differs, with Exenatide approved while GHRP-6 is in Preclinical development. Their sequence patterns also diverge, with Exenatide showing alpha-helical domain features and GHRP-6 showing protein-mimetic sequence features.
