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 MOTS-c improves insulin sensitivity, enhances glycolysis, reduces oxidative stress, and shows protective effects in models of metabolic syndrome, aging, and ischemia-reperfusion injury8135146, Tesamorelin is FDA-approved to reduce excess visceral adipose tissue in HIV-associated lipodystrophy and is studied for broader body-composition, NAFLD, and cognitive effects via GH/IGF-1 axis modulation1893.
While MOTS-c works as 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, Tesamorelin is a full-length 44-amino-acid GHRH analog with an N-terminal trans-3-hexenoic acid modification that binds GHRHR, activating cAMP/PKA signaling to increase endogenous GH and IGF-1, with improved stability versus native GHRH182893102.

Both peptides fall into a similar broad context as Metabolic peptides, although the details of how they are used and discussed still diverge. Both are often discussed in Metabolic and endocrine contexts, while MOTS-c is more of a mitochondrial peptide and Tesamorelin is better described as a hormone peptide. They also influence different molecular systems, with MOTS-c tracking more closely to Mitochondrial membrane while Tesamorelin centers more on Growth hormone axis. MOTS-c has a more mitochondrial-encoded origin, while Tesamorelin is closer to synthetic analog background and their development context also differs, with MOTS-c in Preclinical development while Tesamorelin is approved. MOTS-c takes the form of a linear peptide, whereas Tesamorelin is closer to a peptide conjugate, Tesamorelin incorporates amidation features that are not part of MOTS-c; while their sequence patterns also diverge, with MOTS-c showing hydrophobic domain features and Tesamorelin showing alpha-helical domain features.
