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.

Rixa Health bundles weight-loss medication and visits into one price and does not charge until after approval. The direct-to-consumer functional-medicine practice prescribes compounded and oral semaglutide and tirzepatide, plus other peptides, through partner US pharmacies. Board-certified DO and FNP providers take a root-cause approach and require monthly follow-ups for the first six months. It is cash-pay only and available in nearly all states, with a few listed as coming soon. Compounded, not branded, GLP-1 is the focus.

KERNX Health
What we like
- Semaglutide costs $209 a month, close to the $185 median for compounded semaglutide across the sellers we compare
- Shows its price before the medical questionnaire, so you can compare it without handing over health information
- The monthly price stays the same as your dose goes up
- The monthly price includes the medication, clinician visits and shipping
- Serves all 50 states
- We found no FDA warning letters issued to KERNX Health
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
- 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
Rixa Health
What we like
- The monthly price includes the medication and clinician visits
- Serves all 50 states
- We found no FDA warning letters issued to Rixa Health
- A live video visit with a clinician is required before a prescription, which is slower than a form and is the more careful intake
Watch-outs
- 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
