Peptides for Weight Loss
GLP-1 agonists and targeted peptides are transforming medical weight loss. Compare protocols, costs, and providers.
Overview
Peptide therapy has become one of the most effective medical approaches to sustainable weight loss. GLP-1 receptor agonists like Semaglutide and Tirzepatide have demonstrated 15–20% body weight reduction in clinical trials, while compounded peptides like AOD-9604 target fat metabolism directly. With RFK Jr. moving to reclassify several peptides for legal compounding in 2026, access to these therapies is expanding rapidly.
Key Benefits
- Appetite suppression and reduced cravings
- Targeted fat metabolism without muscle loss
- Improved insulin sensitivity and blood sugar control
- Sustainable long-term weight management
- Potential cardiovascular benefits (GLP-1s)

Frequently Asked Questions
How much weight can you lose with peptide therapy?
Clinical trials show GLP-1 agonists like Semaglutide can produce 15–20% body weight loss over 68 weeks. Individual results vary based on dosage, diet, exercise, and starting weight. Compounded peptides like AOD-9604 have less clinical data but are commonly reported to support 5–10% body weight reduction.
Are weight loss peptides safe?
FDA-approved GLP-1s (Semaglutide, Tirzepatide) have undergone rigorous clinical trials. Common side effects include nausea, constipation, and injection site reactions. Compounded peptides have less safety data. Always work with a licensed provider who monitors your health throughout treatment.
How much do weight loss peptides cost?
Compounded Semaglutide typically costs $200–$500/month. Brand-name Wegovy or Zepbound can cost $1,000–$1,500/month without insurance. AOD-9604 runs $100–$250/month from compounding pharmacies.
Do I need a prescription for weight loss peptides?
Yes. All peptide therapies for weight loss require a prescription from a licensed healthcare provider. Many telehealth providers on our platform can evaluate you remotely and prescribe if appropriate.
What is the RFK peptide reclassification?
In 2026, HHS Secretary Robert F. Kennedy Jr. announced plans to reclassify 14–19 peptides previously banned from compounding pharmacies, including AOD-9604. This would make these peptides legally available through regulated compounding pharmacies for the first time since 2023.
