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, 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.
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, GHRP-2 is 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.

Argireline and GHRP-2 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 GHRP-2 is more often associated with the realm of Metabolic and endocrine and Musculoskeletal health. They also influence different molecular systems, with Argireline tracking more closely to SNARE complex while GHRP-2 centers more on Ghrelin receptor. Both are synthetic in origin and their development context also differs, with Argireline cosmetic grade while GHRP-2 is in Clinical phase 1. Argireline carries acetylation features, while GHRP-2 instead reflects d-amino acid substitution and amidation changes.
