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 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 glycation51150159154, TB-500 is studied for enhancing musculoskeletal and cardiac repair, wound healing, and promoting cell migration and differentiation via actin cytoskeleton remodeling21255.
While Acetyl tetrapeptide-5 works as a synthetic tetrapeptide, Ac-βAla-His-Ser-His (Eyeseryl), with reported ACE-1 inhibition and anti-glycation activity, proposed to improve microcirculation and reduce capillary permeability and fluid accumulation in periorbital tissues51150159157, TB-500 is a synthetic peptide comprising the LKKTETQ actin-binding motif of thymosin beta-4 that binds G-actin, sequesters actin monomers, and promotes cell migration, angiogenesis, and tissue repair1255.

Both peptides fall into a similar broad context as Signal peptides, although the details of how they are used and discussed still diverge. Their typical research and application settings separate fairly clearly: Acetyl tetrapeptide-5 is more often discussed in the realm of Dermatology and aesthetics, whereas TB-500 is more often associated with the realm of Musculoskeletal health and Cardiovascular health. Both appear to work through Signaling modulator, but the functional emphasis still separates, with Acetyl tetrapeptide-5 leaning toward Anti-inflammatory and TB-500 leaning toward Tissue repair and healing and Angiogenesis modulation. Acetyl tetrapeptide-5 has a more synthetic design origin, while TB-500 is closer to synthetic analog background and their development context also differs, with Acetyl tetrapeptide-5 cosmetic grade while TB-500 is in Preclinical development. Acetyl tetrapeptide-5 incorporates acetylation features that are not part of TB-500.
