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 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 trials71111115, Selank is a peptide developed in Russia as an anxiolytic and nootropic; in animal models it reduces anxiety-like behavior and modulates immune parameters under stress39.
While AOD-9604 works as a synthetic fragment of human growth hormone corresponding to residues 176–191 with an added N-terminal tyrosine, retaining lipolytic but not growth-promoting actions; proposed to stimulate lipolysis and inhibit lipogenesis in adipose tissue, partly via β3-adrenergic pathways without significantly activating the full GH receptor–IGF-1 axis6171111, Selank is a synthetic heptapeptide, Thr-Lys-Pro-Arg-Pro-Gly-Pro, that combines a tuftsin fragment with a Pro-Gly-Pro motif and is reported to modulate GABAergic neurotransmission and cytokine balance while being resistant to proteolytic degradation39.

AOD-9604 and Selank are noticeably different, with limited direct overlap in their usual biological context. Their typical research and application settings separate fairly clearly: AOD-9604 is more often discussed in the realm of Metabolic and endocrine, whereas Selank is more often associated with the realm of Neurology and brain health and Immunology and inflammation. Their biological logic is quite different: AOD-9604 is a hormone analog, whereas Selank is a neurotransmitter modulator and a signaling modulator. Both are synthetic in origin with AOD-9604 in Preclinical development and Selank approved for Research use only. Their sequence patterns also diverge, with AOD-9604 showing hydrophobic domain features and Selank showing proline-rich features.
