Question 1

How does the health assessment work?

Accepted Answer

It takes about 2 minutes. We ask about your health goals, diet, lifestyle, sleep, and exercise habits. Our AI analyzes your responses against clinical research to build a stack tailored to your specific profile.

Question 2

How does the AI determine my recommendations?

Accepted Answer

Our recommendation engine cross-references your health data with peer-reviewed research on nutrient interactions, bioavailability, and dosing protocols. It's not a simple quiz-to-product mapping — it's a genuine analysis of what your body likely needs.

Question 3

Can I retake the assessment if my goals change?

Accepted Answer

Absolutely. Your health evolves, and your stack should too. Retake the assessment anytime from your account dashboard, and we'll update your recommendations accordingly.

Question 4

Is the quiz based on real science?

Accepted Answer

Every question maps to a clinical variable. We don't ask anything for fun. Our recommendation logic is built on published research and reviewed by our science advisory team.

Question 5

What if I'm already taking supplements?

Accepted Answer

Tell us in the assessment. We factor in what you're currently taking to avoid redundancy and ensure safe dosing. We'd rather you take less than double up on something you don't need.

Question 6

Where are your supplements sourced?

Accepted Answer

We source from GMP-certified facilities in the US and Europe. Every ingredient is third-party tested for purity and potency. We publish our sourcing partners — no black-box supply chains.

Question 7

Are the supplements third-party tested?

Accepted Answer

Yes, every batch. We test for heavy metals, microbial contamination, and label accuracy. Certificates of analysis are available upon request.

Question 8

How are the doses determined?

Accepted Answer

Doses are based on clinically studied amounts — not the bare minimums you'll find in most multivitamins. We reference established upper limits and your personal data to find the right therapeutic dose for you.

Question 9

What's actually in my daily pack?

Accepted Answer

Your pack contains individual capsules for each supplement in your stack. Every capsule is clearly labeled. No proprietary blends, no mystery powders. You'll know exactly what you're taking and why.

Question 10

Are there any fillers or artificial ingredients?

Accepted Answer

We use minimal excipients — only what's necessary for capsule stability and bioavailability. No artificial colors, flavors, or unnecessary fillers.

Question 11

How much does Stack cost?

Accepted Answer

Stack Core is $69/month. Individual supplements are also available for one-time purchase or subscription. You'll see your exact price after completing the health assessment.

Question 12

Can I pause or cancel anytime?

Accepted Answer

Yes, with no penalties. Pause or cancel from your account dashboard before your next billing date. We don't believe in trapping people.

Question 13

How often am I billed?

Accepted Answer

Monthly. Each shipment is a 30-day supply. You can adjust your delivery frequency from your account if you need more time between shipments.

Question 14

Can I change my stack after subscribing?

Accepted Answer

Yes. Retake the health assessment anytime. If your recommendations change, your next shipment will reflect the updated stack.

Question 15

Do you offer a money-back guarantee?

Accepted Answer

We offer a 30-day satisfaction guarantee on your first order. If you're not happy with your stack, contact us and we'll make it right.

Question 16

How long does shipping take?

Accepted Answer

Standard shipping is 3-5 business days within the US. Expedited options are available at checkout.

Question 17

How do I track my order?

Accepted Answer

You'll receive a tracking number via email as soon as your order ships. You can also check order status from your account dashboard.

Question 18

Do you ship internationally?

Accepted Answer

We currently ship within the United States. International shipping is on our roadmap — join our waitlist to be notified.

Question 19

What if my package is lost or damaged?
