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 Hexarelin is investigated for effects on GH secretion, cardiac protection, and muscle metabolism, with higher GH secretory potency than earlier GHRPs1929, Tirzepatide is approved for type 2 diabetes and obesity, producing larger HbA1c and body-weight reductions than semaglutide in head-to-head trials24.
While Hexarelin works as a potent synthetic hexapeptide (examorelin) that agonizes GHSR-1a to stimulate GH release and also binds CD36, influencing cardiovascular and metabolic pathways19212996, 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.

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 and Cardiovascular health contexts, while Hexarelin is more of a hormone peptide and Tirzepatide is better described as a metabolic peptide. Both appear to work through Receptor agonist, but the functional emphasis still separates, with Hexarelin leaning toward Anabolic growth and Tirzepatide leaning toward Metabolic regulation. Hexarelin has a more synthetic design origin, while Tirzepatide is closer to synthetic analog background and their development context also differs, with Hexarelin in Preclinical development while Tirzepatide is approved. Hexarelin takes the form of a linear peptide, whereas Tirzepatide is closer to a peptide conjugate, while their sequence patterns also diverge, with Hexarelin showing protein-mimetic sequence features and Tirzepatide showing alpha-helical domain features.
