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

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 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 effects111, Hexarelin is investigated for effects on GH secretion, cardiac protection, and muscle metabolism, with higher GH secretory potency than earlier GHRPs1929.
While BPC-157 works as a synthetic 15-amino-acid fragment of a gastric cytoprotective protein that promotes angiogenesis and tissue protection primarily by modulating VEGFR2 signaling, Src/caveolin-1–dependent eNOS activation, and nitric oxide production111, Hexarelin is a potent synthetic hexapeptide (examorelin) that agonizes GHSR-1a to stimulate GH release and also binds CD36, influencing cardiovascular and metabolic pathways19212996.

BPC-157 and Hexarelin are noticeably different, with limited direct overlap in their usual biological context. Their typical research and application settings separate fairly clearly: BPC-157 is more often discussed in the realm of Gastroenterology, Musculoskeletal health, and Dermatology and aesthetics, whereas Hexarelin is more often associated with the realm of Metabolic and endocrine and Cardiovascular health. Their biological logic is quite different: BPC-157 is a signaling modulator, whereas Hexarelin is a receptor agonist. BPC-157 has a more synthetic analog origin, while Hexarelin is closer to synthetic design background and both are still best understood as being in Preclinical development. Hexarelin incorporates d-amino acid substitution and amidation features that are not part of BPC-157, while their sequence patterns also diverge, with BPC-157 showing proline-rich features and Hexarelin showing protein-mimetic sequence features.
