Showing 20 peptides in Weight Loss
GLP-1 Receptor Agonist
FDA-approved GLP-1 agonist for weight loss and type 2 diabetes.
GIP/GLP-1 Receptor Agonist
Dual GIP/GLP-1 agonist for weight loss and type 2 diabetes.
GLP-1 Receptor Agonist
FDA-approved GLP-1 receptor agonist for weight management and type 2 diabetes.
Triple Incretin Agonist
Retatrutide (LY3437943) is an investigational triple GLP-1/GIP/glucagon receptor agonist from Eli Lilly. In Phase 2 obesity trials it produced up to ~24% mean weight loss at 48 weeks — the highest reported for any obesity drug — but it is not FDA-approved and has no legal commercial source as of 2026.
Amylin Analogue
Cagrilintide is a long-acting amylin analogue in Phase 3 development, studied in combination with semaglutide (CagriSema). The CagriSema combination achieved approximately 22.7% body weight reduction at 68 weeks in the SCALE trial.
GLP-1/Glucagon Dual Agonist
Survodutide (BI 456906) is a dual GLP-1 and glucagon receptor agonist in Phase 3 trials for obesity and MASH (metabolic-associated steatohepatitis), demonstrating approximately 14.9% weight loss at 46 weeks in Phase 2b studies.
GLP-1/Glucagon Dual Agonist
Mazdutide (IBI362) is a weekly GLP-1 and glucagon receptor dual agonist developed by Innovent Biologics, currently in Phase 3 trials in China. Phase 3 GLORY-1 trial data showed 14.5% body weight reduction over 36 weeks.
Amino Acid Derivative
L-Carnitine is a conditionally essential amino acid derivative (β-hydroxy-γ-trimethylaminobutyric acid) that facilitates the transport of long-chain fatty acids across the inner mitochondrial membrane for β-oxidation, serving as a critical cofactor in energy metabolism.
Growth Hormone Releasing Hormone Analog
Tesamorelin is a synthetic research peptide and stabilized analog of growth hormone–releasing hormone (GHRH).
Peptide Blend
CagriSema, a compounded combination of the amylin analogue cagrilintide and the GLP-1 agonist semaglutide, studied in Phase 3 REDEFINE trials with approximately 22.7% body weight reduction at 68 weeks.
Growth Hormone Secretagogue
A research peptide blend formulated to investigate growth hormone axis modulation through combined GHRH and ghrelin receptor pathways.
AICAR is a research compound that acts as an AMP analog activating AMP-activated protein kinase (AMPK).
O-304 is a synthetic small-molecule research compound developed to modulate cellular senescence-associated pathways.
Targeted proapoptotic compound
Adipotide, also known as FTPP, is a synthetic research peptide designed as a targeted proapoptotic compound.
Growth Hormone Fragment
AOD-9604 is a research peptide consisting of amino acids 177–191 of the human growth hormone sequence.
Peptide Blend
A triple-peptide compounded blend combining AOD-9604 (fat-mobilizing GH fragment) with CJC-1295 and ipamorelin for comprehensive GH-axis optimization with targeted lipolysis.
Peptide Blend
A compounded blend combining ipamorelin (ghrelin receptor agonist) with tesamorelin (GHRH analogue) for synergistic GH secretion with tesamorelin's additional visceral fat-reducing properties.
Triple Monoamine Reuptake Inhibitor
Tesofensine is a synthetic small-molecule research compound classified as a triple monoamine reuptake inhibitor.
Mitochondrial-Derived Peptide
MOTS-c is a mitochondrial-derived peptide composed of 16 amino acids.
5-amino-1MQ is a small-molecule research compound that functions as a selective nicotinamide N-methyltransferase (NNMT) inhibitor.
