The difference is in the evidence

We name the study, not just the claim.

Every product page sets out what the research actually shows and flags where it is early. When a study is small, mixed or industry funded, we say so on the page. We would rather lose a sale than mislead you.

Why SPAN

Credibility over hype.

The longevity market runs on confidence it has not earned. We would rather show you the limits of the evidence than sell you past them.

Curated, not catalogued

Eleven products, not fifteen hundred. Every SKU earned its place, and we tell you what the research actually says, limitations included.

Tiers for everyone

Start with the high-leverage basics for under $70 a month. Go as deep as you want from there. No gatekeeping at either end.

The science, cited

We name the researchers and note when evidence is early. We'll tell you when not to buy something, because we'd rather lose a sale than mislead you.

It evolves with you

When the research changes, we update, and we tell you. Your protocol is a living thing, not a one-time purchase.

Find your protocol

A protocol, not a shopping cart.

Most supplement stores hand you 1,500 products and wish you luck. We learn what you want to optimize, where you are now, and what you can invest, then hand you a ranked stack instead of a list.
