Every question, answered honestly
The questions people actually type into search boxes, answered by someone with the test results in their app and the ambassador dashboard open in another tab.
What is the current Superpower discount code?
The code is superpower20. It takes a flat $20 off a Superpower membership at checkout, and I last verified it on July 21, 2026. It's my own ambassador code, issued through Superpower's official program. How to redeem it, step by step →
How much does the code take off?
A flat $20. The $199 membership becomes $179 in most states; the $399 New York/New Jersey price becomes $379. It's a fixed dollar discount, not a percentage. The full cost breakdown →
Is there a bigger Superpower promo code, like 30% or 50% off?
No. Superpower issues ambassador codes centrally through its program, and they're all worth the same flat $20 — there's no hidden tier and no influencer with a better arrangement. Coupon sites advertising 30 to 50% off Superpower are listing invented or expired codes to win a click; you'll reach checkout and find they don't apply. Why no code is worth more →
Does the code expire?
Superpower can rotate codes, which is why this site carries a verified date instead of pretending codes last forever. I re-test superpower20 monthly against a live checkout. If it ever changes, the site updates the same day I find out, and the current code will always be the one on the homepage.
Where do I enter the code?
In the discount-code field on the payment step of superpower.com's membership signup. Paste it, apply it, and confirm the total dropped by $20 before paying. There's a full walkthrough on the how-to-redeem page. The four-step walkthrough →
Is Superpower legit?
Yes. It's a venture-backed San Francisco health company founded in 2023, with a $30M Series A led by Forerunner in 2025. Testing runs through CLIA-certified labs (the draws happen at Quest Diagnostics locations) with physician ordering and review. I'm a paying member; my experience is written up in the review. The company, with sources →
How does Superpower compare to Function Health?
Function Health costs $365 a year to Superpower's $199 ($179 with the code), and for that they test more markers (160+ against 100+) across two draws a year instead of one. Superpower is roughly half the price, outright and per marker. Both draw at Quest, neither takes insurance, and both are HSA/FSA eligible. I'm a Superpower ambassador and earn nothing from Function, so read that with the appropriate suspicion — and read the full side-by-side, where I say who should pick them instead. The full side-by-side →
Do I have to fast before the test?
Yes, from the night before your draw. Water is fine. Book a morning appointment: mine was 8:30am, and by 9:00 I was done and eating breakfast. An afternoon slot means an entire fasted morning for no benefit. The whole draw, start to finish →
How many vials does the Superpower blood test take?
Seven or eight, which is the one thing about the process that genuinely surprised me. A standard physical takes one or two. The panel is large enough that it isn't run as a single test — different vials go to different labs depending on the marker, some out of state — so the vial count is a consequence of the panel's breadth. It isn't painful, it just takes a moment longer than you expect. Why nobody warns you about this →
How long do results take?
They arrive in waves, not all at once. My first markers appeared about 48 hours after the draw, most filled in over the week, and the slowest (testosterone, routed to an out-of-state lab) took a full week. Plan for "about a week," not "next morning." My day-by-day timeline →
Can I pay with HSA/FSA funds?
The membership is HSA/FSA eligible. You can request an itemized receipt from Superpower (members@superpower.com) to submit for reimbursement. Insurance is not currently accepted.
What happens to my health data?
Superpower publishes its data posture plainly: HIPAA administrative, physical and technical safeguards; SOC 2-aligned security, availability, confidentiality, processing-integrity and privacy controls; encryption of health data at rest and in transit with least-privilege access and audit logs; CLIA-certified labs with physician ordering, review and documented QA; escalation timelines for flagged results; and member rights to download, correct, or request deletion of your data. What they actually measure →
Is this site official?
No, and that's the point of being clear about it. This is an independent site run by a Superpower member who is an official ambassador. When you join with superpower20 I earn a commission at no extra cost to you, which is disclosed on every page. Superpower's own site is superpower.com.
