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 Hexarelin is investigated for effects on GH secretion, cardiac protection, and muscle metabolism, with higher GH secretory potency than earlier GHRPs1929, 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 Hexarelin works as a potent synthetic hexapeptide (examorelin) that agonizes GHSR-1a to stimulate GH release and also binds CD36, influencing cardiovascular and metabolic pathways19212996, 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 Hormone peptides, although the details of how they are used and discussed still diverge. Both are often discussed in Metabolic and endocrine and Cardiovascular health contexts, while Hexarelin is more of a hormone peptide and Tesamorelin is better described as a metabolic peptide. Both appear to work through Receptor agonist, but the functional emphasis still separates, with Hexarelin leaning toward Anabolic growth and Lipolysis and fat loss and Tesamorelin leaning toward Metabolic regulation. Hexarelin has a more synthetic design origin, while Tesamorelin is closer to synthetic analog background and their development context also differs, with Hexarelin in Preclinical development while Tesamorelin is approved. Hexarelin takes the form of a linear peptide, whereas Tesamorelin is closer to a peptide conjugate, while their sequence patterns also diverge, with Hexarelin showing protein-mimetic sequence features and Tesamorelin showing alpha-helical domain features.
