ABOUT · SUBJECT N°001 · ON FILE SINCE 2014

Hi. I’m Saulo.

Brazilian-American, fifty-three, restaurateur in Seattle. I’m running a longevity experiment on myself, in public, on a normal person’s budget. This is what that means.

Why this.

I spent the first half of my forties at 103 kilograms — about 227 pounds. I got down to 71 kg over the course of a decade, mostly the hard way, with a few protocols I didn’t understand at the time. (That story is in the journal.) Somewhere along the way I crossed fifty and started thinking less about how I looked and more about whether I would be there when my grandchildren remembered me.

Emma is three. Matthew is one. The arithmetic is simple. If I want to be the grandpa they remember showing up — not the one in faded photos — I have to make it to my mid-eighties in working order. From fifty-three, that’s another thirty-plus years of healthspan I have to engineer for. That is what this is. I’m not chasing immortality. I’m trying to be there.

The premise.

There is a man named Bryan Johnson who has built a very public, very expensive blueprint for slowing his own aging. Reported budget: north of two million dollars a year. Reported team: thirty-plus people. The protocol is fascinating and serious and not available to anyone outside the top zero-point-one percent of net worth.

I am not in the top zero-point-one percent. I am a working restaurateur with two kids and two grandkids and a mortgage. The thesis of this site is that most of what makes the Blueprint work is now accessible to ordinary people — not all of it, but most of what matters — and that the missing piece for ordinary people has never been the protocol. It has been the interpretation layer.

The interpretation layer is what’s new. AI models can now read longitudinal biometric data the way a $200,000-a-year endocrinologist would. (That story is also in the journal.) The protocols themselves — GLP-1s, statins, metformin, peptides, the supplement stack, the wearables — are all available at the corner pharmacy or on Amazon. The question is whether a normal person, with normal funds, can produce Blueprint-class results.

The answer, as of May 2026, is: I don’t know yet. That’s why it’s called an experiment.

What this is

A public n=1 trial.

One subject (me), every protocol disclosed, every dollar spent shown, every lab result published, every dashboard public.

What this is not

Medical advice.

I’m not a doctor. Every intervention I use was prescribed by one. Your biology is not my biology.

Who it’s for

Men 40 — 60 who already own wearables and want to actually use them.

If you have an Apple Watch and a smart scale and a folder of “all normal” labs, this site is for you.

The day jobs.

I run two restaurants in Seattle. Both predate this experiment by years. Owning food and beverage businesses is occupationally hazardous to longevity in ways that probably do not need spelling out — alcohol, late hours, free dessert, stress. Part of what this site is documenting is how to live inside that exposure on purpose, without pretending the exposure isn’t there.

The other day job.

Before the restaurants there were twelve years in enterprise cloud — AWS, Azure, Oracle. Solutions architect, technical account manager, support engineer. The kind of work that involves staring at dashboards full of telemetry and figuring out which line on which chart matters. That training, it turns out, is exactly what reading your own biometric data is. The dashboards just happen to be inside a body now.

What you’ll find here.

The dashboard is the current state — every active protocol, every supplement, every biomarker, every cost. Updated as I learn things. The journal is the work behind the dashboard — what each new lab panel meant, what each protocol change actually moved, the small revelations and the big ones. The homepage is the experiment in one screen.

The disclaimer that matters. The Vita Experiment documents one man’s personal health optimization journey. I am not a doctor, and nothing on this site constitutes medical advice. Every intervention used has been prescribed by a licensed physician — currently a US primary-care doctor (Dr. Tolani), a Brazilian functional-medicine physician (Dra. Penélope Tabatinga), and a dermatologist (Dra. Mayara Ferro). My results are n=1. Your genetics, history, and circumstances are different. Consult your own healthcare provider before changing anything in your protocol.
