Head-to-head · Cost-Efficiency Index
SkinnyRx vs Amazon One Medical
Two GLP-1 programs on the bench, scored on the same six factors. Here's how their real cost of ownership compares — and which one we'd start with.
SkinnyRx
Shoppers who have already decided on a long commitment and want the term priced openly rather than hidden behind an intake — not price-first shoppers comparing on the advertised figure.
Visit SkinnyRxAmazon One Medical
Patients who specifically want a real FDA-approved branded medication (Wegovy, Zepbound, or Foundayo) rather than a compounded alternative, and already shop on Amazon.
Visit Amazon One MedicalThe verdict
Amazon One Medical takes it, leading the Cost-Efficiency Index 73 to 71. Amazon One Medical's GLP-1 program (health.amazon.com/onemedical) is a branded-only prescribing service it will not write compounded prescriptions that charges a separate ~$39 initial care fee from the medication cost itself. SkinnyRx still earns a C — Shoppers who have already decided on a long commitment and want the term priced openly rather than hidden behind an intake — not price-first shoppers comparing on the advertised figure.
Worth knowing either way: our overall #1 pick is CoreAge Rx (Cost-Efficiency Index 94/100 — the top of the ranking). See how it stacks up: CoreAge Rx vs Amazon One Medical.

SkinnyRx
71/100Where the value is
- A complete four-term ladder for both molecules is published rather than gated, so the cost of not committing is knowable before signup
- Both compounded molecules are offered, with the same term structure on each
- The twelve-month rate is genuinely low for the category if a year is a commitment you were going to make anyway
The tradeoffs
- The '$199/month' it advertises everywhere is the TWELVE-MONTH rung. The rate you can stop after a month is $349 — 75% higher — and the figure appears without that term attached
- An FDA warning letter is on public record against Lean Rx, Inc. dba SkinnyRx, issued 20 February 2026. We disclose it and we do not treat it as disqualifying
Regulatory note: the FDA issued a warning letter to Lean Rx, Inc. dba SkinnyRx in February 2026. We still list and link to SkinnyRx; you should know the letter is on the public record before you decide.
Amazon One Medical
73/100Where the value is
- Prescribes only FDA-approved branded medications — no compounded product risk, which in this ranking only LillyDirect also avoids
- Same-day medication delivery available in roughly 3,000 cities via Amazon Pharmacy's existing logistics network
- One Medical membership is explicitly optional, not a gate, to access GLP-1 care
The tradeoffs
- The care fee (~$39-$49) and the medication cost are billed completely separately — the site itself warns 'the cost of your prescribed medication is not included with the treatment price,' so no single headline number captures the real all-in cost
- The lowest advertised Rx price ('$149 with coupon if eligible') is conditional on manufacturer coupon eligibility, not guaranteed to every patient
