How to build a longevity protocol: intake, labs, safety gate, human review, coach, check-ins

Thirteen articles on what the evidence says; this one is on how it becomes a plan for one person. The method is the same for every goal on this site and it is deliberately unglamorous: measure first, exclude what is unsafe, write the cheapest version that can honestly work, and check the numbers before changing anything.

Before you read onResearch and educational information for adults, not medical advice. This article explains what the research says about one part of ageing — what is measurable, what is modifiable and what is still hype. It is not your protocol, and nothing here diagnoses, treats, cures or prevents any condition. Baseline labs come before anything, and your own physician has the final word. Longevity Bros offers coaching and written research protocols only — we do not sell, supply, source or ship any compound.

What a longevity protocol is — and is not

A personal research protocol is a written plan for one adult and one goal, over one cycle of usually twelve weeks, built from an intake and a set of labs, written by a person, checked by a second person and released by a coach. For a longevity goal the plan has six layers, and the sequence they are written in is the point: training, nutrition, sleep, labs, supplements, and — only where the labs allow and the goal needs it — the compound layer. Clinic therapies, where they appear, are placed in a specific week of that plan and performed by licensed providers.

It is not a prescription, a diagnosis or a treatment. It is not a list of compounds with a lifestyle paragraph at the bottom. And it does not come with anything in a box: Longevity Bros writes the plan and coaches you through it, and does not sell, supply, source or ship any compound. The protocol lists what it assumes, and the sourcing, the physician conversation and the decision are yours.

The method, step by step

StepWhat happensHow longOutput
1. IntakeAbout fifteen minutes of honest answers in the Research Protocol Builder: goal, training history, sleep, diet, medicines, medical history, budget, what you have already tried. Labs can be uploaded now or later.15 minA structured intake the writer works from.
2. LabsThe baseline panel: ApoB, hsCRP, HbA1c, fasting insulin, cystatin C, ferritin, vitamin D, thyroid, a sex-hormone panel, IGF-1, full blood count — plus VO2max, grip and a DEXA where the goal needs them.Book now; results in daysThe numbers the plan is written against. Without them the first version is provisional and says so.
3. Safety gateThe exclusions are applied before anyone writes: pregnancy, active cancer, under 18, a history of restrictive eating for any fasting element, and the compound-specific red flags — haematocrit, IGF-1, kidney function, interactions with prescribed medicines.Same dayEither a green light or a message explaining what must be resolved first, with your physician.
4. Human-written protocolA writer drafts from the intake and labs; a reviewer checks every threshold, dose and interaction; a coach releases. No template is pasted — the reviewer's job is to find the thing the writer missed.Typically within 24 hours of a complete intakeThe protocol.
5. Three documentsA short results version for your phone — what to do this week; the full clinical document with the week-by-week schedule, the lab plan, the stop rules and the reasoning; and a physician copy written for your own doctor.TogetherThe same plan at three depths.
6. Coach callFree, on WhatsApp: the plan walked through, your labs read against it, your questions answered, the first two weeks set up.30–45 minA plan you understand.
7. Check-insWeek 2 (is it working in practice), mid-cycle (the lab repeat decides whether anything holds, steps or stops), end of cycle (what changed, what next). Any new labs trigger a revision.Through the cycleA protocol that changes when the numbers do.

Budget first

Every protocol is written in its budget version first: the fewest moving parts — and, where the compound layer is used, the fewest pens — that can honestly move the goal. For a longevity goal that version often contains no compound at all for the first cycle, because the levers with the strongest evidence are free: three zone-2 sessions and one interval session, two lifting sessions, 1.6 g/kg of protein, a fixed wake time, and the five supplements the labs justify. The upgrade — a compound studied for sleep, recovery or body composition, a clinic therapy in the repair weeks — is written as an option and unlocked at a check-in once the labs and the first weeks have earned it. The budget-versus-upgrade guide explains the logic.

This is not austerity. It is how you find out what worked. A plan that starts with everything cannot tell you which part moved the number, and the second cycle is written blind.

What a longevity protocol usually contains

What to measure

The protocol lists its own, but the longevity set is always the same five, repeated at the same points:

The how-to-read-your-protocol guide shows where each of these sits in the documents, and the twelve-week-cycle guide explains why the cycle has the shape it has.

Where peptides and therapies fit

Last, and gated. In a longevity protocol the compound layer, when it is used, is studied for three things: sleep architecture, recovery and body composition — the levers the earlier articles identify as modifiable — and each compound page in the research library lists the labs it depends on and the mistakes we see. The protocols-by-goal hub shows how the same method produces different plans for fat loss, lean mass, sleep or immunity, and the therapies section grades each clinic offer by evidence so that a protocol can say where it fits — or that it does not. The baseline-labs guide is the gate everything passes through first.

Common mistakes

Frequently asked questions

How long does it take to get a protocol?

About fifteen minutes of intake, then typically within 24 hours of a complete intake for the human-reviewed protocol. If labs arrive later, the plan is revised against them at no extra cost.

What do I get for €399?

The intake, the safety gate, a human-written and human-reviewed protocol, three documents — the results version, the full clinical document and a physician copy — a free coach call on WhatsApp, check-ins at week 2, mid-cycle and the end, and any revision when new labs arrive. No subscription; nothing in a box.

Do I need labs before I start?

The plan is written against them, so yes — book the baseline panel when you start the intake. If you upload later, the first version is provisional and says which parts depend on the results. Kidney function is always cystatin C, never creatinine alone.

Does the protocol include compounds?

Only where the goal needs them and the labs allow, and often not in the first cycle of a longevity plan, because the strongest levers are training, sleep and nutrition. Where a compound is included, the protocol describes what it is studied for, the labs it depends on and the stop rules. Longevity Bros does not sell, supply, source or ship any compound.

What happens at the end of twelve weeks?

The baseline is repeated — labs, VO2max, DEXA — and the end-of-cycle check-in reads what changed. The second cycle is written from those numbers: the upgrade if the first cycle earned it, a different lever if it did not, or a break if the plan says so.
