The comparison in brief

CoreAge Rx has the higher Cost-Efficiency Index: 94/100 versus 77/100. That is a value comparison under our published methodology, not a measure of medical suitability or a guarantee of results.

The better fit depends on what is included in your quote. A lower advertised price can require prepayment, apply to a starting dose or leave out a separate fee.

CoreAge Rx

Anyone who wants one flat monthly price they can plan a full year around, on either molecule, without signing a contract.

Reasons to consider it

  • One price at every dose: semaglutide is $99 from 0.25 mg up to 2.5 mg, and tirzepatide is $149 from 2.5 mg up to 15 mg
  • No membership fee, no insurance needed and no long-term contract, and the price you lock in at checkout stays put as your dose rises
  • If the doctor decides a prescription isn't right for you, CoreAge refunds the medication portion of your payment

What to weigh up

  • Some programs we track publish lower semaglutide prices. Compare billing terms, dose pricing and required fees before choosing.
  • You pay before the doctor reviews your case, and if you aren't approved the FAQ promises a 100% refund while the refund policy keeps a $50 to $100 consultation fee
  • All sales are final once medication ships, because state and federal law don't allow medication returns

Compounded drugs are not FDA-approved. Understand the medication options.

Knownwell

Insured shoppers who want an obesity-medicine specialist overseeing brand-name GLP-1 care, with published self-pay drug prices as a fallback.

Reasons to consider it

  • Co-founded and clinically led by Dr. Angela Fitch, a named, credentialed obesity-medicine specialist (Chief Medical Officer)
  • Prescribes branded FDA-approved GLP-1s across the current class (Wegovy, Zepbound, Ozempic, Saxenda) plus orforglipron/Foundayo
  • Publishes a self-pay price for every drug and dose, from $149 a month for the Wegovy pill

What to weigh up

  • Brand-name only, and the price rises with the dose: the Wegovy pill runs $149 to $299 a month, the Wegovy pen $349, and Zepbound $299 to $449
  • Those are medication prices; without insurance, knownwell's own visits cost $299 for the first and $149 for each follow-up
  • In-person care is limited to five states (Texas has primary care in Plano only), so most of the country can only use the virtual clinic
