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 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, Tirzepatide is approved for type 2 diabetes and obesity, producing larger HbA1c and body-weight reductions than semaglutide in head-to-head trials24.
While Tesamorelin works as 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, Tirzepatide is a 39-amino-acid synthetic peptide primarily based on GIP sequence with C20 fatty diacid conjugation that acts as a dual agonist at GIP and GLP-1 receptors, enhancing glucose-dependent insulin secretion, suppressing glucagon, delaying gastric emptying, and reducing appetite24.

Both peptides fall into a similar broad context as Hormone peptide and Metabolic peptide, 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 Tesamorelin is more of a hormone peptide and Metabolic peptide and Tirzepatide is better described as a metabolic peptide and Hormone peptide. Both appear to work through Receptor agonist, but the functional emphasis still separates, with Tesamorelin leaning toward Anabolic growth and Tirzepatide leaning toward Metabolic regulation and Lipolysis and fat loss. Both are synthetic in origin. Tesamorelin carries amidation features, while Tirzepatide instead reflects lipidation and d-amino acid substitution changes.
