Noom Med vs PlexusDx

Both sell tirzepatide. Noom Med costs $149 a month and PlexusDx costs $189, a difference of $40 a month or about $480 a year. The other differences matter more than the money if this is your first course.

Noom Med is behaviour change alongside medication. PlexusDx is pharmacy transparency and genetic testing. They are not aimed at the same person, and the cheaper one is not automatically the right answer — particularly if this is your first course and you expect a slow titration.

What this means for your titration. PlexusDx holds one price at every dose and Noom Med does not — so this gap widens as you titrate toward a therapeutic dose, exactly when you can least afford a surprise.

The differences that affect treatment

4 of these affect how treatment actually goes. The rest are administrative.

What each programme publishes: Noom Med

• Noom Med listed from $149/month.

Where it wins: The coaching is the actual product here and it is well built. Watch for: A $79 microdose programme is not the same treatment as 10 mg tirzepatide. Check the dose before comparing on price.

What each programme publishes: PlexusDx

• GLP-1 weight-loss programmes start at $129/month.
• Publicly names six 503A pharmacy partners: Belmar, Strive, Epiq Scripts, Casa Pharma Rx, The Pharmacy Hub and Foothills.
• Clinical oversight via LionMD, with named physicians and NPI numbers published.

Where it wins: The most detailed pharmacy disclosure in this comparison — six named 503A partners. Watch for: The advertised "from $129" is the programme floor. Budget $189/month for the compounded injection tier.

Strengths of each

Noom Med.

• The coaching is the actual product here and it is well built.
• Medication is included in the microdose tier rather than billed separately.
• Straightforward cancellation.

PlexusDx.

• The most detailed pharmacy disclosure in this comparison — six named 503A partners.
• Names its prescribing physicians along with their NPI numbers.
• No membership fee, and flat pricing across the dose range.

PlexusDx scores higher overall at 4.4 out of 5. The weights are published on how we rate, and so is the note about which of these is our paid featured partner.

Which suits you

If this is your first course, weight the two rows about dose pricing above everything else. A programme that keeps the price flat lets you stop climbing when your body says so, and that single freedom does more for whether you are still taking this in month three than $40 a month does.

The verdict

For most people starting out, Noom Med at $149 a month is the more defensible choice on arithmetic alone. PlexusDx earns its premium only if you will actually use what it does differently. Read the full reviews before deciding: Noom Med and PlexusDx.
