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, PEG-MGF is used experimentally to enhance muscle repair and hypertrophy after mechanical overload or injury by stimulating satellite-cell activation and protein synthesis6373138.
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, PEG-MGF is a poly(ethylene glycol)-conjugated form of Mechano Growth Factor (IGF-1Ec splice variant) comprising the 24-aa C-terminal E-peptide of IGF-1, designed to extend half-life while activating IGF-1 receptor–mediated anabolic signaling in muscle satellite cells637322138.

PEG-MGF
IGF1
Both peptides fall into a similar broad context as Signal peptides, although the details of how they are used and discussed still diverge. Both are most often discussed in Musculoskeletal health, which gives the comparison a meaningful common setting even when the rest of their profiles are not identical. Both appear to work through Signaling modulator, but the functional emphasis still separates, with BPC-157 leaning toward Angiogenesis modulation and Anti-inflammatory and PEG-MGF leaning toward Anabolic growth. Both are synthetic in origin and both are still best understood as being in Preclinical development. BPC-157 takes the form of a linear peptide, whereas PEG-MGF is closer to a peptide conjugate, PEG-MGF incorporates pegylation features that are not part of BPC-157; while their sequence patterns also diverge, with BPC-157 showing proline-rich features and PEG-MGF showing protein-mimetic sequence features.
