How can we help?

BioStack signs you in with an email link, so there is no password to remember. Enter your email on the sign-in page and we send you a one-time link. Open it and you are in.

The link works once and expires after 15 minutes. If you see “expired or already used”, ask for a new one.

Once you are signed in you can add a passkey from Account Security for one-tap sign-in on that device.

Check your spam or promotions folder and make sure you typed the address correctly. Links expire after 15 minutes, so ask for a new one if yours is old.

If it still does not arrive, send us a message through the contact form (choose Support) or email us, and tell us which address you used. Do not send us the link itself.

Before you save anything, BioStack asks you to agree to a short statement. It covers the profile details, items, amounts, and logs you choose to save, which is health-related information, and you decide what goes in. We do not sell your data and we do not use it for ads.

If you choose “Not now”, you can still read the public library. Nothing you saved is deleted unless you delete it. Anything that is not switched on yet is asked about again, with an on/off switch, before it starts for you.

Open Your Data from the menu and choose Download JSON or Download CSV. JSON keeps the structure. CSV gives you one spreadsheet per list, in a zip file. Passwords, sign-in link secrets, and passkey keys are never included.

Open Your Data from the menu and find Delete your account. Type the phrase shown on the page, and we email you a one-time link. Open that link in the same browser within 15 minutes and confirm. Nothing is deleted until you confirm on that last page.

Deleting is permanent. Your profiles, items, dose logs, check-ins, protocols, notes, alert settings, sign-in details, and sessions are removed from live systems. Backups age out within 35 days. A paid plan is cancelled, and our payment provider may keep its own billing records where tax rules require it. We keep a small record that a deletion happened, with a random id, the date, and a row count, and nothing in it identifies you.

Download a copy first if you want one. We cannot bring deleted data back.

BioStack is a public library of what the research says about peptides and similar compounds, graded by evidence strength. If you create an account you can also keep your own record of what you take, with logs, check-ins, and a timeline, and use tools such as the unit converter and the volume and reconstitution calculators.

No. BioStack never tells you what to take or how much, and it does not fill in, suggest, or work out an amount for you. Amounts come only from you. The calculators do arithmetic on numbers you enter, such as a concentration, and do not choose an amount.

BioStack is not medical advice. It is not a doctor, a pharmacy, or an emergency service. For medical decisions, talk to a qualified clinician. If something feels wrong, contact a clinician or your local emergency services.

In Everything I’m Taking you can add supplements, vitamins, research compounds, or anything else. BioStack checks what you typed against its library and may offer a match for you to confirm. If it cannot verify an item, it stays in your list exactly as you wrote it, marked Unverified. If BioStack offers a match, you choose whether to accept it.

Each claim in the library is graded on seven tiers: Established, Plausible Theory, Early Evidence, Anecdotal Signal, Contradicted, Unsupported, Hype Exceeds Evidence. A tier describes how strong the sources are for that specific claim. It does not say whether something is suitable for you.

Send us a message through the contact form and choose Feedback. Tell us the compound, the exact claim or number, and what you think is wrong. A source makes a report much easier to check, so include a PubMed ID, a DOI, or a link if you have one.

Use the contact form, or email support@biostack.cc. In the form, pick the category that fits (Support, Billing, Feedback, Partnership, or Other), include the email you want us to reply to, and tell us what happened and what you expected. We reply by email.

Please do not put passwords or sign-in links in a message.

No. Support cannot give medical advice and is not an emergency service. For a medical concern, contact a clinician or your local emergency services.

Signed-in members can open Billing and choose Manage Billing to manage your subscription. Payments are handled by Stripe. If Manage Billing does not open for your account, contact us, choose Billing, and tell us the email you sign in with.
