Compounded GLP-1 medications
- Compounded GLP-1What a compounded GLP-1 actually is, the difference between a 503A pharmacy and a 503B outsourcing facility, why the category survived the end of the shortages, what the FDA has done about it in 2026, and the six things to check before buying one.Updated September 16, 2026
- Compounded tirzepatideWhat compounded tirzepatide is, how it differs from Zepbound and Mounjaro, what it is compounded with, whether it is still legal in 2026, what the FDA says about safety, and what telehealth providers charge.Updated September 12, 2026

GLP-1 safety
- Compounded semaglutide safetyThe honest answer, from FDA records rather than marketing: 990 adverse-event reports, dosing errors of five to 20 times the intended dose, unapproved salt forms, and a product nobody has reviewed for quality. What the risks actually are and how to reduce them.Updated September 16, 2026
- Compounded tirzepatide safetyEvery side effect in the tirzepatide label with its rate, the serious reactions worth knowing by name, and the risks that belong to compounding rather than to the drug — 730+ FDA reports, dosing errors, and ingredients nobody checked.Updated September 16, 2026
Brand-name GLP-1 medications
- Mounjaro vs OzempicTwo once-weekly injections, two different molecules, and one head-to-head trial in the FDA labels. What each is approved for, what the trials measured, how the side effects compare, what each costs to self-pay, and why neither is a weight-loss drug on paper.Updated September 16, 2026
- Best GLP-1 for weight lossFive GLP-1 medicines are FDA-approved for weight loss in the US, and their trials produced very different numbers. The label results side by side, injections against pills, what each costs to self-pay, and why the biggest number is not automatically the right drug.Updated September 16, 2026
