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 GHRP-6 is used experimentally to produce strong GH surges and hyperphagia, allowing investigation of GH-dependent anabolism and energy-balance regulation2030, Tirzepatide is approved for type 2 diabetes and obesity, producing larger HbA1c and body-weight reductions than semaglutide in head-to-head trials24.
While GHRP-6 works as a first-generation synthetic hexapeptide ghrelin mimetic that potently stimulates GH release and markedly increases appetite via GHSR-1a activation in hypothalamus and pituitary203096, 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 contexts, while GHRP-6 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 GHRP-6 leaning toward Anabolic growth and Tirzepatide leaning toward Metabolic regulation. GHRP-6 has a more synthetic design origin, while Tirzepatide is closer to synthetic analog background and their development context also differs, with GHRP-6 in Preclinical development while Tirzepatide is approved. GHRP-6 takes the form of a linear peptide, whereas Tirzepatide is closer to a peptide conjugate, while their sequence patterns also diverge, with GHRP-6 showing protein-mimetic sequence features and Tirzepatide showing alpha-helical domain features.
