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-2 is used in research to induce robust GH pulses and study anabolic and metabolic effects; clinically developed as pralmorelin for GH deficiency diagnostics6272, Matrixyl is a widely used cosmetic peptide with evidence of stimulating extracellular matrix synthesis and reducing wrinkle appearance in skin-care formulations48.
While GHRP-2 works as a second-generation hexapeptide growth hormone–releasing peptide that mimics ghrelin by agonizing GHSR-1a, strongly stimulating pulsatile GH release and modestly raising prolactin, ACTH, and cortisol62723096, Matrixyl is a palmitoylated pentapeptide, Pal-Lys-Thr-Thr-Lys-Ser (Pal-KTTKS), that acts as a matrikine, signaling to dermal fibroblasts to increase production of collagen, elastin, fibronectin, and other ECM components4858.

GHRP-2 and Matrixyl are noticeably different, with limited direct overlap in their usual biological context. Their typical research and application settings separate fairly clearly: GHRP-2 is more often discussed in the realm of Metabolic and endocrine and Musculoskeletal health, whereas Matrixyl is more often associated with the realm of Dermatology and aesthetics. They also influence different molecular systems, with GHRP-2 tracking more closely to Ghrelin receptor while Matrixyl centers more on Extracellular matrix proteins. Both are synthetic in origin and their development context also differs, with GHRP-2 in Clinical phase 1 while Matrixyl is cosmetic grade. GHRP-2 takes the form of a linear peptide, whereas Matrixyl is closer to a peptide conjugate, while GHRP-2 carries d-amino acid substitution and amidation features, while Matrixyl instead reflects palmitoylation changes.
