Weight LossPreclinical

5-Amino-1MQ

5-amino-1-methylquinolinium

A selective NNMT (nicotinamide N-methyltransferase) inhibitor that enhances cellular energy metabolism. Not technically a peptide but a small molecule research compound. Mouse studies showed 30%+ decrease in adipocyte size.

Animal Studies50-75 mg daily
Weight LossIn Clinical Trials

AOD-9604

Anti-Obesity Drug 9604

A modified fragment of human growth hormone (amino acids 177-191) studied for fat metabolism effects without the broader hormonal effects of full GH.

Clinical Trials300 mcg daily
Weight LossNot FDA Approved

CagriSema

Semaglutide + Cagrilintide

Investigational combination therapy demonstrating 22.7% body weight reduction at 68 weeks in Phase 3 trials, outperforming semaglutide monotherapy.

Clinical TrialsSemaglutide 2.4mg + Cagrilintide 2.4mg weekly
Weight LossNot FDA Approved

Cagrilintide

AM833

Long-acting amylin analog for obesity treatment operating through distinct pathways compared to GLP-1 agonists. Phase 3: 11.8% weight loss (monotherapy); 20.4% (CagriSema combination).

Clinical Trials2.4 mg weekly
Weight LossFDA Approved

Dulaglutide

Trulicity

An FDA-approved weekly GLP-1 receptor agonist for type 2 diabetes. Fused to an Fc antibody fragment for extended duration (~5 day half-life).

FDA Approved1.5-4.5 mg weekly

HGH Fragment 176-191

Frag 176-191

The lipolytic fragment of human growth hormone. Contains the fat-burning portion of HGH without effects on blood sugar or cell proliferation.

Clinical Trials250-500 mcg daily
Weight LossFDA Approved

Liraglutide

Victoza
