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

InstaRX

Readers considering an annual compounded plan who will verify the full upfront charge, medication and cancellation terms first.

Reasons to consider it

  • Public product pages show the annual-prepayment basis of the advertised price
  • Says the price stays the same at every dose
  • The $45 consultation fee is included rather than added on top

What to weigh up

  • The $265 monthly average requires twelve months prepaid; shorter-plan prices and the full annual charge need confirmation
  • The semaglutide product page incorrectly describes tirzepatide, so confirm the actual prescribed medication
  • No dispensing pharmacy or individual medical director is named
