Straight answers, no pitch.

You tell us what supplements you take. We audit the stack against peer-reviewed research and structured heuristics, then return a verdict: what to keep, what to cut, what to fix, and the specific reason. The audit covers dose vs. effective range, absorption conflicts, timing, redundancy, and form.

No. StackRoast is for informational and educational purposes only. It synthesizes what the research says; it does not replace a physician or pharmacist. If you have a diagnosed condition, are pregnant, or take prescription medications, your doctor should have the final say on your protocol.

Every finding shows its work: evidence tier, dose ranges, and sourcing. We also publish what the audit cannot do, so you can judge for yourself.

No. Well-dosed, evidence-backed supplements get a Keep verdict. The audit flags what is underdosed, redundant, conflicting, or unsupported, and tells you the specific reason.

The full audit report costs $9, paid once. Nothing renews and we never upsell.

No account required. You buy the report once and it arrives in your email. There is nothing to log in to and nothing to cancel later.

Your report arrives privately by email, usually within minutes of purchase. If it has not arrived after an hour, check spam and search for "StackRoast," then contact us with your purchase date.

The free preview shows real, specific findings from your stack so you can see the value before paying. The paid report is the complete audit: the full set of findings, the reasoning, dose targets, and fixes across your entire stack.

Reports are digital and arrive instantly, so all sales are final once a report has shipped. If a technical problem stopped you from receiving or accessing yours, email us within 7 days and we will resolve it or refund you.

Yes. Stripe processes payments. We never see or store your full card details, and we will never ask for payment information by email.

We use your email to deliver your report and your supplement inputs to generate the audit. We do not sell your personal information. The full detail of what we collect and why is in the privacy policy.

We feed your inputs into the audit, and our AI provider (Anthropic) generates the report from that context. On the standard API, Anthropic does not use that data to train their models. We treat your information as sensitive.

We use essential cookies (for things like checkout) and privacy-friendly analytics to understand general usage trends. We do not run third-party advertising networks on the site.

No. StackRoast is not affiliated with, endorsed by, or sponsored by any supplement manufacturer. Grades and commentary are our own opinions, and a product appearing in your audit is never a paid placement.

Some links to products are affiliate links, meaning we may earn a commission if you buy through them, at no extra cost to you. A link is never an endorsement, and it never changes a verdict.
