Short answer
They are close on price and labs: Function is $365 for 160+ tests, Superpower is $349 for 150+ biomarkers, and both draw blood at Quest. Function sells tests only and adds a clinician’s written summary. Superpower sells supplements, peptides and prescriptions on top of the test, which is why we rate it lower. Neither publishes its renewal price.
Where they match
Both are annual memberships with two blood draws a year, both use Quest Diagnostics labs, and both cover ApoB, Lp(a), hs-CRP, HbA1c and fasting insulin. Function’s headline price is $365 and Superpower’s is $349, with a $299 new-member offer visible in Superpower’s page code when we checked on 30 September 2026.
Where they differ
Function sells nothing but the test and its add-on scans, and every result comes with a clinician-written summary. Superpower is built as a platform: it can prescribe medications, sells supplements at member prices, and lists add-ons for gut, toxins, peptides and a multi-cancer test. It also reads data from Oura, Whoop and Apple Health.
For a referee, that difference matters. A company that profits from what it recommends after your results has a reason to find something to recommend. That is criterion four of our clean-testing standard, and Superpower leans fail on it.
What neither tells you up front
Neither publishes what year two costs. Function’s at-home draw and New York or New Jersey surcharge aren’t priced. Superpower doesn’t serve nine states and doesn’t show at-home pricing. If you only want the four highest-evidence numbers, both are more than you need: Labcorp OnDemand sells them for about $180 combined.
