Comparison · Bloodwork & longevity

Function Health, Superpower vs OneTwenty

All three sell an annual membership built around a large blood panel. They differ in what the panel covers, what it costs once you add follow-up tests, and whether anyone can prescribe treatment after your results come back.

The short answer

Choose OneTwenty if…

People who want their blood retested every 90 days (a 101-marker baseline plus three follow-up panels a year) and want custom supplements and prescriptions, at published prices, driven by those results in one membership.

Visit onetwenty.com ↗

Choose Function Health if…

Adults who want twice-yearly broad lab testing at a flat cash price and do not need prescribing or treatment from the same service.

Visit functionhealth.com ↗

Choose Superpower if…

Cost-conscious adults wanting an annual baseline lab panel plus optional access to prescriptions through the same app, and who accept that medication prices are not published.

Price: what you actually pay

Function Health

Pricing page (seen 2026-11-05): '$1/day', 'Charged annually at $365'; includes '160+ lab tests annually' across two draws (100+ tests at the annual visit, 60+ tests 3 to 6 months later), clinician review of every result and a personalized protocol. Footnote: the $365 first-year price applies in all states except New York and New Jersey, where testing costs more (amount not stated). Add-on tests and imaging cost extra; the FAQ lists the Annual MRI at $999 for members. Terms s.13(b)(i): the subscription auto-renews at Function's then-current price.

Superpower

Homepage (seen 2026-11-05): 'Starts at $199/year' ('$0.55/day'); includes one comprehensive blood draw per year, which Superpower describes as '100+ biomarkers' (its own comparison pages count 103: 57 distinct and 46 calculated), biological age and health scores, action plan, AI and on-demand care team. New members are offered a complimentary follow-up test (stated value $99). An at-home draw is $119 extra. Follow-up tests, add-on tests and prescriptions are priced separately; the homepage says 'Pricing may vary for members in New York and New Jersey' and the comparison pages state +$200 there ($399/yr). Peptides page (seen 2026-11-05): BPC-157 and TB-500 $149/mo, MOTS-c $199/mo, taken as paid pre-orders with a target ship date of late November 2026; the peptide plan includes a 40+ biomarker blood test and membership.

OneTwenty

Pricing page (seen 2026-11-05; the page says its prices were checked on 2 November 2026): $499 a year, billed annually, for four lab panels: a 101-marker baseline (OneTwenty's own count) plus three follow-up panels of 20 to 40 markers, one every 90 days ('161 to 221 lab results a year'). Walk-in draws at Quest are included; an at-home draw is $99 per draw. NY and NJ: $749 a year because Quest cannot be used there. Add-ons: custom supplement packs from $45/mo; extra lab panels 'at cost' (no prices listed). Medications are priced per product on each treatment page: metformin and sildenafil $49/mo, tadalafil $79/mo, GHK-Cu cream and testosterone cypionate $99/mo, enclomiphene, glutathione (injection or nasal) and oxytocin $129/mo, sermorelin and NAD+ (injection or nasal) $149/mo, compounded semaglutide $179/mo, PT-141 $199/mo, tirzepatide $279/mo or $749 billed quarterly. Whether a separate provider consultation fee applies is not stated.

What we like

  • Four lab panels a year (101-marker baseline plus three 20 to 40 marker follow-ups) are included in the membership price
  • Membership and every available medication have a published monthly price: $499/yr ($749/yr in NY/NJ), medications $49 to $279/mo

Watch out for

  • The annual membership is non-refundable after a 7-day window, and only if no service has started (3% fee applies)
  • Not a medical practice: prescriptions come from unnamed third-party telehealth providers, and the site does not say whether they are physicians or NPs or whether visits are by video
  • Early-stage company: it opened a closed beta of 25 founding members in December 2025 and still advertises founding membership
  • No direct insurance billing (HSA/FSA reimbursement only)
