About Longevixx
Finish the eligibility questionnaire and the numbers appear: microdose $129, semaglutide $149, oral $229, tirzepatide $299. Dosage does not move any of them, so titrating up leaves the bill where it was, and each plan carries a dietitian visit, care coaching, physician review and the drug. Longevixx LLC operates out of Charlotte, North Carolina under physician leadership, with a deep peptide menu beside the compounded semaglutide, compounded tirzepatide, daily oral GLP-1 and microdose protocol.

- The monthly price includes the medication, clinician visits, shipping and coaching

Watch-outs
- Tirzepatide costs $299 a month, 20% above the $250 median for compounded tirzepatide across the sellers we compare
- You only see a price after finishing the medical intake, so you cannot compare costs before sharing health information
- Ask which pharmacy fills the prescription before you pay, so you can check its license
- Its semaglutide and tirzepatide are compounded rather than FDA-approved, so they have not been reviewed by the agency for safety, effectiveness or manufacturing quality
