About MyStack

MyStack is a public profile for people who take their own health and performance seriously and want a single, honest place to document it. One page — mystack.bio/yourhandle — holds your current protocol, your supplement stack with full dose-period history, your self-experiments with before/after biomarkers, your bloodwork as marker series, and a timeline of all of it.

It's the link you paste when someone asks "what are you actually taking?" — a page, not a feed. Entries render as ledger lines, like this one:

The product is built so that documentation quality is the only thing that pays off — never extremeness. Concluding an experiment requires an outcome label, and the vocabulary has no euphemisms in it:

A null result and a result that made things worse are first-class outcomes, shown as plainly as a win. Stopped supplements stay on your page with the reason and how long you took it:

Every measured value carries a "self-reported" chip. Nothing here is peer-reviewed or clinical, and the design never pretends otherwise.

MyStack never recommends a dose, a supplement, or a treatment — not to you and not to your readers. You document your own regimen, doses included, because that is what documentation is. A page you read is one person's record of their own choices; it is not a prescription for yours. There are no vendor or affiliate links for compounds, ever.

Everything you add is private by default. Publishing anything health-related the first time asks for explicit consent, logged with a timestamp. Pseudonymous handles are first-class — your real name is never required. Your data lives in the EU, and a full export and a hard account deletion are rights, not features you have to ask for.

A cohort documents people who independently chose to follow the same protocol — each keeping their own before/after log. Joining forks the protocol to a private copy of your own; what you record stays yours and stays private until you publish it. Results appear only as an anonymous group summary once enough consenting participants complete — never as identifiable rows, and never as an effect claim.

MyStack runs a connector for the AI assistant you already pay for — Claude or ChatGPT can read your record and add entries in your own words ("log that I started 5g creatine this morning"). Anything an assistant adds lands private, exactly as if you'd typed it yourself. A connected app can never publish, delete, or export anything — publishing health data stays a deliberate human act, behind its own consent step. Connecting is optional and not the default: the paste importer and the editors do everything the connector does without your data leaving for an LLM.

MyStack is a small, independent project. Questions, corrections, and reports go to a human — every public page has a discreet report link in its footer.
