About KERNX Health

Flat monthly plans for compounded semaglutide and tirzepatide, run out of Washington DC, with one price at every dose and the provider consultation inside the plan rather than billed per visit. The gap is upstream of the price: KERNX no longer names the pharmacy that fills the vial, describing it only as the licensed dispensing pharmacy identified in your treatment and fulfillment information.

About LifespanningRx

Its Weight Loss Program writes compounded injectable GLP-1, semaglutide and tirzepatide, sitting inside a wider set of peptide and healthy-aging protocols. A provider review and good-faith exam come first; 503A/503B licensed US pharmacies then compound, and licensed clinicians stay attached while parcels go out discreetly nationwide. LifespanningRx also licenses the whole thing out, running a turnkey white-label platform so clinics and wellness brands can launch identical programs. Certification is LegitScript, and it states HIPAA compliance.

Pros & Cons

KERNX Health

What we like

  • Semaglutide costs $209 a month, close to the $185 median for compounded semaglutide across the sellers we compare

Watch-outs

  • Tirzepatide costs $299 a month, 20% above the $250 median for compounded tirzepatide across the sellers we compare
  • Not included in the monthly price: lab work
  • Ask which pharmacy fills the prescription before you pay, so you can check its license
