Booking: easier than a dentist appointment

I booked directly on superpower.com. You enter your address and it lists Quest Diagnostics locations near you. There happened to be one close to my house, which made the whole thing convenient. I picked a slot for the very next day.

One planning note: the panel requires fasting from the night before, so take the earliest slot you can get. I chose 8:30am, and by 9:00 I was eating breakfast in the car.

The draw: quick, with one surprise

Check-in was a small kiosk, the wait was about five minutes, and the draw itself was fast. The surprise: they filled seven or eight vials. I wasn't expecting that, so I asked the phlebotomist. Her explanation made sense: a panel this large isn't run as one test. Different vials go to different labs depending on the marker, some of them out of state.

It isn't painful or dramatic, it just takes a moment longer than the two-vial physical you might be used to. Worth knowing in advance.

The wait: results roll in, they don't arrive

Day 0 Booked online; next-day appointment available
Day 1 8:30am fasted draw at Quest: kiosk check-in, ~5 minute wait, 7-8 vials
Day 3 First results appear in the app (~48 hours after the draw)
Days 3-7 Markers fill in throughout the week as different labs report back
Day 8 Last result lands: testosterone, which traveled from New Mexico to a Texas lab

If you're expecting one big reveal, recalibrate: results arrive in waves as each lab finishes. The slowest marker for me was testosterone, at a full week. That's a Quest routing quirk more than a Superpower one (every Quest-based service I've tried behaves this way), but it's the honest timeline.

The app is the actual product

Nobody searching for a discount code gets told this: at the lab, every blood-testing membership is the same needle. The differentiator is what happens to your numbers afterward, and this is where Superpower pulls ahead.

Every biomarker, readable at a glance. Each marker shows your numerical value against its range, color-coded and labeled: optimal, in range, or out of range. You don't have to decode lab-speak.
A timeline across tests. Retest next year and the app tracks each marker's movement, which is the whole point of annual testing.
Action steps for out-of-range markers. Concrete suggestions like supplements to discuss or follow-ups to consider, rather than a bare red flag.
A Superpower Score and a biological age. Algorithmic summaries of the full panel. You might be 35 on paper and read as 30 in your biology, or the reverse. Reductive? A little. Motivating? Genuinely.
Device integrations for Apple Watch, Fitbit, Oura and others, feeding a daily health score. I haven't used this (I don't own a wearable), so I can't vouch for it, but the idea of one dashboard synthesizing labs plus daily metrics is compelling.

What I'd complain about

Nobody warns you about the vial count. Seven or eight vials is fine, but it should be on the booking screen, not a surprise in the chair.
The rolling results create a lopsided week. Watching most markers arrive while one panel dawdles in another state is mildly maddening if you're the refresh-the-app type.

Neither changed my verdict. Both are things I'd want to know going in.

Privacy, since you should ask

A company holding 100+ of your biomarkers should be held to a high bar. Superpower publishes its posture plainly: HIPAA safeguards across its systems, SOC 2-aligned controls, encryption of health data at rest and in transit, CLIA-certified labs with physician ordering and review, and member rights to download, correct, or delete your data. The full rundown is in the FAQ.

Bottom line

I keep coming back to the same frame: the draw is a commodity, the app is the product, and Superpower's app is the best version of that product I've used. If the panel and the software sound useful to you, the membership is worth its price, and there's no reason to pay the sticker.
