Metabolic & Fat-Loss Peptides

Peptides that act on fat metabolism outside the GLP-1 pathway — growth hormone fragments, amylin analogs, and small-molecule metabolic modulators.

5 peptides in this class

5-Amino-1MQ

Target: NNMT (nicotinamide N-methyltransferase) inhibitor

5-Amino-1MQ is a small molecule that inhibits NNMT (nicotinamide N-methyltransferase), an enzyme linked to fat accumulation and metabolic dysfunction. By blocking NNMT, it may increase NAD+ levels, boost cellular energy, promote fat loss, and support metabolic health. Studied for obesity, type 2 diabetes, and longevity applications.

Dose: 50–150 mg daily oral

AOD-9604

Target: C-terminal hGH fragment (fat metabolism)

AOD-9604 is a modified fragment of human growth hormone (HGH fragment 176-191) studied for fat metabolism and weight loss. It mimics GH's lipolytic effects without affecting blood sugar or growth. Previously in clinical trials for obesity; now popular in research settings.

Half-life: ~30 minutesDose: 300 mcg daily SC

Cagrilintide

Target: Amylin & calcitonin receptors

Cagrilintide is Novo Nordisk's long-acting amylin analog designed for weight management. Phase 2 trials showed 11.8% body weight loss as monotherapy and up to 17.1% when combined with semaglutide (CagriSema). Works by enhancing satiety and slowing gastric emptying through amylin receptor activation.

Half-life: ~8 days (weekly dosing)Dose: 0.3–4.5 mg weekly SC

SLU-PP-332

Target: ERRα/β/γ (estrogen-related receptor pan-agonist)

A small-molecule ERR receptor agonist that acts like exercise inside your cells — driving mitochondrial biogenesis, fat oxidation, and endurance gains without any actual training.

Half-life: Plasma + muscle exposure ~6h post-IP injection in mice; oral bioavailability is debated.Dose: Mouse studies: 25–50 mg/kg IP twice daily. Community oral protocols: 500–1500 mcg daily.

Tesofensine

Target: Serotonin–norepinephrine–dopamine reuptake inhibitor

Tesofensine is a serotonin-noradrenaline-dopamine reuptake inhibitor (SNDRI) originally developed for Parkinson's and Alzheimer's disease. Phase 2 trials showed remarkable weight loss of up to 12.8% over 6 months — more than double most approved obesity drugs. Works by reducing appetite and increasing satiety through triple monoamine reuptake inhibition.

Half-life: ~9 days (daily dosing)Dose: 0.25–1 mg daily oral
