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 GHRP-6 is used experimentally to produce strong GH surges and hyperphagia, allowing investigation of GH-dependent anabolism and energy-balance regulation2030, MOTS-c improves insulin sensitivity, enhances glycolysis, reduces oxidative stress, and shows protective effects in models of metabolic syndrome, aging, and ischemia-reperfusion injury8135146.
While GHRP-6 works as a first-generation synthetic hexapeptide ghrelin mimetic that potently stimulates GH release and markedly increases appetite via GHSR-1a activation in hypothalamus and pituitary203096, MOTS-c is a 16-amino-acid mitochondrial-derived peptide that translocates to the nucleus under metabolic stress and regulates glucose and lipid metabolism largely via activation of AMPK and modulation of mTOR and folate-cycle–linked pathways854140146.

GHRP-6 and MOTS-c are noticeably different, with limited direct overlap in their usual biological context. Both are often discussed in Metabolic and endocrine contexts, while GHRP-6 is more of a hormone peptide and MOTS-c is better described as a mitochondrial peptide and Metabolic peptide. They also influence different molecular systems, with GHRP-6 tracking more closely to Ghrelin receptor while MOTS-c centers more on Mitochondrial membrane. GHRP-6 has a more synthetic design origin, while MOTS-c is closer to mitochondrial-encoded background and both are still best understood as being in Preclinical development. GHRP-6 incorporates d-amino acid substitution and amidation features that are not part of MOTS-c, while their sequence patterns also diverge, with GHRP-6 showing protein-mimetic sequence features and MOTS-c showing hydrophobic domain features.
