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, Semax is used clinically in Russia for ischemic stroke and cognitive disorders; in models it improves learning, protects dopaminergic neurons, and modulates stress responses without significant endocrine ACTH-like effects166174.
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, Semax is a synthetic heptapeptide, Met-Glu-His-Phe-Pro-Gly-Pro (MEHFPGP), that is an analog of ACTH(4–10) with a Pro-Gly-Pro extension and exerts neurotrophic and neuroprotective actions partly via upregulation of BDNF and modulation of dopaminergic and glutamatergic systems40162165174.
BPC-157
VEGFR2 (vascular endothelial growth factor receptor 2) on endothelial cells, with downstream eNOS and nitric-oxide–mediated signaling11
Semax
Targets are not fully defined; interacts with melanocortin-related pathways and inhibits certain peptidases, but no single dominant receptor has been established174

Semax
POMC
The clearest overlap between BPC-157 and Semax is that both converge around Signaling modulator. 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 Semax is more often associated with the realm of Neurology and brain health and Ophthalmology. Both appear to work through Signaling modulator, but the functional emphasis still separates, with BPC-157 leaning toward Tissue repair and healing, Angiogenesis modulation, and Anti-inflammatory and Semax leaning toward Neuroprotection and cognition. Both are synthetic in origin with BPC-157 in Preclinical development and Semax approved for Research use only. They share some route overlap through subcutaneous injection, while the remaining routes diverge.
