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 CJC-1295 is used in research to chronically elevate endogenous growth hormone and IGF-1 levels, enabling studies of body composition, metabolic, and anti-aging effects of prolonged GH exposure10, 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.
While CJC-1295 works as a tetrasubstituted 29-amino-acid analog of GHRH(1–29) that acts as a potent agonist at the GHRH receptor and, in its DAC form, covalently binds serum albumin to extend half-life from minutes to days, resulting in sustained pulsatile GH and IGF-1 increase1082, DSIP is 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.

CJC-1295 and DSIP are noticeably different, with limited direct overlap in their usual biological context. Their typical research and application settings separate fairly clearly: CJC-1295 is more often discussed in the realm of Metabolic and endocrine and Aging and longevity, whereas DSIP is more often associated with the realm of Neurology and brain health. Their biological logic is quite different: CJC-1295 is a receptor agonist and a hormone analog, whereas DSIP is a neurotransmitter modulator. CJC-1295 has a more synthetic analog origin, while DSIP is closer to natural endogenous background with CJC-1295 in Preclinical development and DSIP approved for Research use only. CJC-1295 takes the form of a peptide conjugate, whereas DSIP is closer to a linear peptide, while CJC-1295 incorporates d-amino acid substitution features that are not part of DSIP.
