← All research topicsWhat to look for. Which studies measured body weight in people, and which explored a mechanism in animals?
FDA-approved productsSemaglutide
Semaglutide activates GLP-1 receptors, helping regulate appetite, food intake and blood glucose. Prescription products have evidence for weight management or type 2 diabetes, with additional benefits tied to specific indications; practitioners also discuss how to balance response, nutrition and tolerability.
Evidence in this guide: Randomized human trials and product-specific US labels; provider perspectives are identified separately.

Tirzepatide activates GIP and GLP-1 receptors to help regulate blood glucose and food intake. Mounjaro and Zepbound have different treatment indications, while provider discussions often focus on finding a useful maintenance dose with manageable side effects.
Evidence in this guide: Human clinical trials and US product labels, alongside labeled provider perspectives.

Retatrutide activates GIP, GLP-1 and glucagon receptors. Researchers study body-weight, glucose and liver-fat outcomes; community discussions focus on appetite control, gradual dose changes and the lowest amount that feels effective while allowing adequate eating.
Evidence in this guide: Published trials, sponsor results and separately attributed community accounts.
Read the Retatrutide guide ↗Not FDA approvedUBT251
UBT251 targets GLP-1, GIP and glucagon receptors in one investigational molecule. Researchers study its effects on body weight and glucose regulation, while community interest includes how its receptor balance might compare with Retatrutide.
Evidence in this guide: Early human paper, phase 2 conference abstract, sponsor reports and a separate community comparison.

AOD-9604 is a modified growth-hormone fragment investigated for effects on fat metabolism. The original experiments linked here studied metabolic changes and weight gain in obese rats.
Evidence in this guide: Preclinical metabolic experiments; animal body-weight findings are not human efficacy measurements.
