Coreage Rx vs PlexusDx

Both sell tirzepatide. PlexusDx costs $189 a month and Coreage Rx costs $199, a difference of $10 a month or about $120 a year. Here is what that difference actually buys.

Coreage Rx is best overall on true monthly cost. 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 — though it usually is if you are paying cash and tolerate the medication well.

Put plainly. If you picked PlexusDx over Coreage Rx and everything else went the same way, you would be $120 better off after a year. Whether that is the right trade depends on the differences below, not on the number alone.

What actually separates them

They differ on 2 of the 7 things we track. Those differences are what the price gap is buying.

What Coreage Rx publishes

• Compounded tirzepatide starts at $129/month equivalent on a 12-month plan; the one-month plan is $199.
• Compounded semaglutide starts at $79/month equivalent on a 12-month plan; the one-month plan is $139.
• Health coaching is bundled rather than sold as an upgrade.

Where it wins: The advertised price is the billed price — no membership fee arrives in month two. Watch for: The $79 semaglutide and $129 tirzepatide rates require 12-month plans. One-month plans are $139 and $199 respectively. Read the payment and refund terms before committing to a longer plan.

What PlexusDx publishes

• GLP-1 weight-loss programmes start at $129/month.
• Compounded semaglutide injection listed at $189/month with no membership fee and the same price at every dose.
• Clinical oversight via LionMD, with named physicians and NPI numbers published.
• Licensed providers in all 50 states; CLIA-certified labs for its testing line.

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.

Where each is stronger

Coreage Rx.

• The advertised price is the billed price — no membership fee arrives in month two.
• Flat pricing across the dose range, so titrating up to 10 mg or 15 mg does not raise the bill.
• Lowest true monthly cost of any provider in this comparison once fees are included.
• Coaching and clinician access are included rather than sold separately.

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.
• Genetic and blood testing available alongside the prescription.

How they score

Coreage Rx scores higher overall at 4.5 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 should you pick?

If you want the plain answer: PlexusDx, unless one of the differences above matters to you personally. Coreage Rx is not worse — it is aimed at somebody with a different problem, and paying $10 a month more for a problem you do not have is how people end up resenting a treatment that was working.

The verdict

We would tell a friend to start with PlexusDx and move if it disappointed them. That is not a strong claim about either company; it is what the arithmetic supports when nothing else is pulling you.
