What Are the Best Peptides for Weight Loss?

## What Are the Best Peptides for Weight Loss?

Weight loss peptides have gained significant attention in recent years for their potential to promote fat loss, improve body composition, and support overall health goals. Peptides, short chains of amino acids, interact with the body’s natural hormonal systems to influence metabolism, satiety, and fat regulation. This article explores the most effective peptides for weight loss, supported by clinical evidence and credible medical resources.

## Semaglutide (Wegovy, Ozempic)

Semaglutide, commercially available as Wegovy and Ozempic, is a GLP-1 receptor agonist initially developed to treat type 2 diabetes. It mimics the body’s natural incretin hormones, stimulating insulin secretion, suppressing appetite, and promoting feelings of fullness.

Clinical trials have demonstrated substantial weight loss benefits. According to a study published in the [Journal of the American College of Cardiology](https://www.jacc.org/), participants lost between 12.8% and 14.7% of their body weight over 72 weeks. Furthermore, 85% to 90.9% of participants achieved at least 5% weight reduction in the SURMOUNT-1 clinical trial.

Semaglutide is manufactured by pharmaceutical giant [Novo Nordisk](https://www.novonordisk.com//), headquartered in Søborg, Denmark.

## Tirzepatide (Zepbound, Mounjaro)

[Tirzepatide](https://tirzepatide.lilly.com/), marketed as Zepbound and Mounjaro, combines GLP-1 and GIP receptor agonist actions, making it highly effective for sustained weight loss. Clinical results are impressive; the SURMOUNT-1 trial indicated that between 85.1% and 90.9% of participants achieved at least 5% weight loss at 72 weeks, with sustained weight loss up to 25.3% at 88 weeks in the SURMOUNT-4 trial (2025).

Tirzepatide is administered through weekly injections, typically at dosages ranging from 5mg to 15mg. This peptide is developed and distributed by [Eli Lilly and Company](https://www.lilly.com//), based in Indianapolis, Indiana.

## CJC-1295 and Ipamorelin Combination

CJC-1295 and Ipamorelin are growth hormone-releasing peptides frequently paired to enhance their complementary effects. These peptides stimulate the pituitary gland to produce and release growth hormone, promoting fat breakdown and lean muscle mass development.

While clinical trials specific to weight loss outcomes are limited, medical providers have reported noticeable improvements in body composition when these peptides are combined. Clinics such as [EmpowerMed Clinic](https://www.empowermedclinic.com//) in San Diego offer customized peptide therapy plans utilizing CJC-1295 and Ipamorelin, providing monthly body composition assessments to track patient progress.

## AOD 9604

AOD 9604 is a modified form of human growth hormone fragment specifically designed to target fat metabolism. It works by stimulating lipolysis (the breakdown of fat) and inhibiting lipogenesis (fat storage), thereby directly aiding in fat reduction without affecting blood sugar levels or inducing insulin resistance.

While research into AOD 9604 is ongoing, its targeted action on adipose tissue makes it a promising candidate for weight management protocols.

## Liraglutide (Saxenda)

Liraglutide, marketed as Saxenda, is another GLP-1 receptor agonist similar to semaglutide but with a different molecular structure. Clinical studies demonstrate its notable efficacy in weight loss management. Research published in [Frontiers in Molecular Biosciences](https://www.frontiersin.org/journals/molecular-biosciences) indicated an average body weight loss of approximately 12% in participants, coupled with improvements in metabolic markers.

This peptide is particularly beneficial for obesity management, offering substantial weight reduction combined with metabolic improvements.
