TestWell prices are live from the catalog and are what checkout charges. Superpower prices were read from its public ordering pages on 2026-10-22; all-in assumes one test ordered alone.
Is it the same test?
Yes. Both orders are analyzed at the same CLIA-certified lab under the same CPT code (82306), so the assay, the reference range and the number on your report are identical. You are paying for the ordering experience, the physician authorization and any bundling — not a different test.
Where does the price difference come from?
Superpower sells testing as a $199-a-year membership, so its per-test figure only holds if you use the full program. TestWell charges per test — $41.99 plus one $6.00 lab fee per order — which is why a single Vitamin D test is $47.99 with nothing else to buy.
When is Superpower the better choice?
- Lowest per-marker price of the memberships: about $3.49 per directly measured marker ($199 / 57) if you want the whole baseline
- An actual plan: Kin, Superpower's AI, writes a protocol as soon as results land, and a care team answers questions — TestWell gives you the results and the Lab Agent, not coaching
- Wearable integration (Apple Health, Whoop, Oura) and upload of past labs into one record, with biological-age and health scores
- You want someone to turn the numbers into a plan. Superpower's AI protocol and care team are the product; TestWell gives you the lab report and the Lab Agent for questions, not coaching.
- You want wearables, past labs and bloodwork in one app with a biological-age score — TestWell tracks your TestWell results over time, nothing else.
