RNK Health

Shoppers who want one all-in monthly price for a compounded GLP-1 and are fine confirming the exact price for their dose at checkout.

Reasons to consider it

  • One monthly price covers the medication, the physician consultation and prescription, syringes and wipes, and shipping, with no separate membership or visit fee
  • Month to month: you can cancel, pause or skip from your account, and it emails the upcoming amount 7 days before each renewal
  • Both compounded semaglutide and tirzepatide, with NAD+, sermorelin, B12 and naltrexone available on the same account

What to weigh up

  • Both prices are "from" figures and the pages don't say what a higher dose costs, so confirm the price for your dose at checkout
  • Fees are non-refundable once you submit the intake, unless a provider finds you ineligible or the medication arrives damaged or wrong
  • To stop the next charge you have to cancel at least 72 hours before the billing date

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