About Stack
Stack is a private tracking app for people who take more than one thing — supplements, medications, peptides, GLP-1s, TRT — and want one honest log of all of it. No account, no ads, no cloud requirement; data stays encrypted on your device.
Why we publish a compound library
People who track are people who look things up. The library exists so a person logging a compound can read, in plain English, what it is, how it works, how long it lasts and how it's stored — without wading through hype or sales pages. It is a reference for trackers, not a catalog of recommendations.
The sourcing standard
- Public, primary-leaning sources. Entries are summarized from public literature and regulatory materials (FDA labels for approved drugs, published pharmacology for the rest), and each entry carries its source line.
- FDA status stated plainly. Approved uses are quoted as approved; everything else is labeled not FDA-approved. We never blur that line.
- No dosing advice, ever. Where common marketed strengths exist as public facts, we list them as facts. We do not suggest doses, cycles or protocols.
- No sourcing, no sales. We never link to vendors or imply where to buy anything.
- Dated and revisable. Every page shows its last-reviewed date. Spot an error? Email us — corrections ship fast.
Who builds it
Stack is built by a small independent team that tracks its own stacks. We're not clinicians and don't pretend to be — that's exactly why the app and this site never give medical advice, and why every health decision belongs with you and your clinician.
The blunt disclaimer
Nothing on this site or in the app is medical advice, a diagnosis, a treatment recommendation, or an endorsement of any compound. Information may contain errors and can go stale; verify against the original label or literature. Some compounds in the library are not approved for human use anywhere — their inclusion is documentation, not approval.
