Metabolic & appetite
Cagrilintide
A compound that copies some actions of amylin, a hormone involved in appetite and blood sugar. It has been studied in human trials.
Why people are interested
Cagrilintide attracts attention because researchers are testing whether an amylin-like signal can reduce appetite and body weight.
What the research supports
A randomized phase 2 trial in adults with overweight or obesity found weight loss with the studied cagrilintide product. Results for a combination with semaglutide are a separate question.
Clinical or label amounts
Human trial groups
0.3, 0.6, 1.2, 2.4, or 4.5 mg
Once weekly in a phase 2 trial
Specific to the named study or medicine, not this research vial.
Tirzepatide acts on GIP and GLP-1 receptors. It has been studied in human medicine products for blood sugar and metabolic effects.
Why people are interested
Tirzepatide is well known because prescription versions are used for type 2 diabetes, chronic weight management, and certain sleep-apnea patients. JD-2TR is a seller code associated with tirzepatide in listed batch reports.
What the research supports
The strongest evidence belongs to manufactured prescription tirzepatide products studied in clinical trials. FDA approval applies to those products and specific indications, not automatically to a research-only JD-2TR vial.
Clinical or label amounts
Prescription product label
2.5–15 mg
Once weekly in adults

FDA-approved uses belong to named prescription products and indications; they do not transfer to an online research vial. Human, animal, cell, and anecdotal evidence are different. How we check sources →
