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 Dulaglutide is a once-weekly GLP-1RA for type 2 diabetes that lowers HbA1c and body weight by enhancing glucose-dependent insulin secretion and reducing appetite6668, MGF is upregulated in muscle after mechanical overload, where it supports tissue repair and growth; recombinant forms are studied for regenerative and performance-enhancement effects22138.
While Dulaglutide works as a recombinant fusion protein consisting of two disulfide-linked GLP-1(7–37) analogs each covalently fused via a linker to an IgG4 Fc fragment, yielding a large, long-acting GLP-1 receptor agonist protected from DPP-4 degradation66, MGF is a 24-amino-acid E-peptide splice variant of IGF-1 (IGF-1Ec) produced in mechanically stressed or damaged muscle that activates IGF1R and local anabolic pathways involved in muscle repair and hypertrophy22138144.

Dulaglutide and MGF are noticeably different, with limited direct overlap in their usual biological context. Their typical research and application settings separate fairly clearly: Dulaglutide is more often discussed in the realm of Metabolic and endocrine, whereas MGF is more often associated with the realm of Musculoskeletal health. Their biological logic is quite different: Dulaglutide is a receptor agonist, whereas MGF is a growth factor mimetic and a signaling modulator. Dulaglutide has a more engineered peptide origin, while MGF is closer to natural endogenous background and their development context also differs, with Dulaglutide approved while MGF is in Preclinical development. Dulaglutide takes the form of a peptide conjugate, whereas MGF is closer to a linear peptide, while their sequence patterns also diverge, with Dulaglutide showing alpha-helical domain features and MGF showing protein-mimetic sequence features.
