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 DSIP was originally described for inducing spindle and delta sleep activity when infused into the brain of rabbits; later studies report stress-modulating and endocrine effects, though its physiological role is still debated47, GHRP-6 is used experimentally to produce strong GH surges and hyperphagia, allowing investigation of GH-dependent anabolism and energy-balance regulation2030.
While DSIP works as an endogenous nonapeptide, Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu, with proposed neuromodulatory actions; it interacts with components of the MAPK cascade and may be related to glucocorticoid-induced leucine zipper (GILZ), but its precise biosynthetic origin remains unknown4757, GHRP-6 is a first-generation synthetic hexapeptide ghrelin mimetic that potently stimulates GH release and markedly increases appetite via GHSR-1a activation in hypothalamus and pituitary203096.

DSIP and GHRP-6 are noticeably different, with limited direct overlap in their usual biological context. Their typical research and application settings separate fairly clearly: DSIP is more often discussed in the realm of Neurology and brain health, whereas GHRP-6 is more often associated with the realm of Metabolic and endocrine and Musculoskeletal health. Their biological logic is quite different: DSIP is a neurotransmitter modulator, whereas GHRP-6 is a receptor agonist. DSIP has a more natural endogenous origin, while GHRP-6 is closer to synthetic design background with DSIP approved for Research use only and GHRP-6 in Preclinical development. GHRP-6 incorporates d-amino acid substitution and amidation features that are not part of DSIP.
