What are fat loss peptides?

Fat loss peptides are compounds that target specific metabolic pathways to enhance fat burning, reduce fat storage, or suppress appetite. Unlike stimulants, they work through mechanisms like lipolysis stimulation (AOD-9604), growth hormone optimization (Tesamorelin), or neurotransmitter modulation (Tesofensine).

How do fat loss peptides differ from GLP-1 medications?

GLP-1 agonists (Semaglutide, Tirzepatide) primarily work through appetite suppression and are FDA-approved with extensive safety data. Fat loss peptides like AOD-9604 work through direct fat metabolism mechanisms. Tesofensine combines both approaches. GLP-1s typically produce 15-24% weight loss vs 4-13 kg for most fat loss peptides.

What is AOD-9604 and how does it work?

AOD-9604 is a modified fragment (amino acids 176-191) of human growth hormone that retains fat-burning properties without affecting blood sugar, insulin, or muscle growth. It stimulates lipolysis (fat breakdown) and inhibits lipogenesis (fat storage) by targeting beta-adrenergic receptors in adipose tissue.

What results can I expect from AOD-9604?

Clinical trials showed approximately 2.6 kg (5.7 lbs) average fat loss over 12 weeks vs 0.8 kg for placebo - a net difference of about 4 lbs additional fat loss. Results require consistent use for 12+ weeks combined with proper diet and exercise. AOD-9604 works best for stubborn fat deposits.

Is Tesofensine available?

Tesofensine is currently in Phase 3 clinical trials and is not yet FDA-approved. It showed impressive results in Phase 2 trials (11-13 kg weight loss at 0.5mg over 24 weeks). It may be available through clinical trials or specialized research settings but is not widely accessible.

What blood tests should I get for fat loss peptides?

Essential baseline labs include: fasting insulin, fasting glucose, HbA1c, comprehensive metabolic panel (CMP), lipid panel, thyroid panel (TSH, T3, T4), and body composition measurement. These establish metabolic baseline and screen for contraindications like diabetes or thyroid disorders.

Are fat loss peptides safe?

Safety varies by compound. Tesamorelin is FDA-approved with extensive safety data. AOD-9604 has been tested in 900+ participants with minimal side effects. Tesofensine shows mild cardiovascular effects (increased heart rate, blood pressure). Medical supervision is essential for any fat loss peptide protocol.

Can I combine fat loss peptides with other peptides?

Some combinations are used, but should only be done under medical supervision. AOD-9604 is sometimes combined with growth hormone peptides. Tesofensine should not be combined with other monoamine-affecting compounds. Always consult a healthcare provider before stacking any peptides.
