A personal recomposition protocol — less fat, more muscle, and a scale that barely moves

The scale stays within a kilo or two of where it started. The waist loses 4–6 cm, the lifts go up, the clothes fit differently. Recomposition is the goal most people actually want and the one most often done badly — here is what a protocol for it contains.

Before you read onResearch and educational information for adults, not medical advice. This page describes what a protocol for this goal usually looks like — it is not your protocol. Baseline labs come before anything, and your own physician has the final word.

Who this is for

This page is for the adult close to the right weight and nowhere near the right shape. You are maybe 5–8 kg from where you would like to be, but a plain diet makes you smaller and softer, and a plain bulk puts it back on the waist first. Recomposition is the slower, more precise plan: lose fat and add muscle in the same twelve weeks, with the scale demoted to a secondary measure.

A recomposition protocol fits best when most of these are true:

It is not the page for someone who wants it done in four weeks — recomposition is twelve weeks at minimum, and the mirror lags the tape. The hard stops are the same as everywhere: pregnancy, breastfeeding, under 18, active or recent cancer, and the compound-specific exclusions in the safety gate.

What a protocol for this goal usually contains

Recomposition protocols are usually a pairing: a mild appetite or visceral-fat compound on one side, a recovery or growth signal on the other, with the training and protein doing the real work between them. No doses — those are written for you after your labs.

What you'll feel — and when

You'll noticeWhat to expectFrom when
SleepDeeper and heavier on the nightly pairing, often the first change anyone notices.Weeks 1–2
AppetiteQuieter — snacks stop being a negotiation; the small deficit happens on its own.Within the first week
The scaleWithin 1–2 kg of the start for the whole cycle: up a little early as glycogen rises, down a little late as fat leaves. Expected.Throughout
RecoveryLess next-day soreness; sessions feel sustainable rather than a grind.Weeks 2–4
Your waistStarts moving at the tape — typically 1 cm every two weeks, 4–6 cm by week 12 when the training holds.Weeks 4–6 onward
Your liftsHold through weeks 1–4, then a rep or two more on the main lifts by weeks 6–8.Weeks 6–8
The mirror and the clothesThe part that lags: a visibly tighter trunk and fuller shoulders. Judge it in the photos.Weeks 8–12
LabsIGF-1 and glucose at week 6 confirm the pairing; the week-12 panel and the end-of-cycle call decide what comes next.Weeks 6 and 12

Typical ranges from research settings and the researchers we write for — not promises. Most recomposition "failures" are measurement failures: daily weigh-ins, quitting in week 5 with a waist already 2 cm down.

How we build it for you

Here the intake matters most, because the right pairing depends on which side — fat or muscle — has further to go, and on what your labs say.

  1. Intake. Fifteen minutes of honest answers in the Research Protocol Builder. Labs are optional here — upload later and we revise.
  2. Safety gate and baseline labs. The exclusion list first (pregnancy, active cancer, under 18, the compound-specific red flags), then the baseline panel your plan needs — kidney function as cystatin C, never creatinine alone.
  3. Human review. A writer drafts from your intake and labs; a reviewer checks every dose, lab threshold and interaction. Typically within 24 hours.
  4. Three documents. A short results version for your phone, the full clinical document with the week-by-week schedule and lab plan, and a physician copy for your own doctor.
  5. A free coach call on WhatsApp to walk it through and read your labs against the plan.
  6. Check-ins at week 2, mid-cycle and the end. Mid-cycle labs decide whether the dose holds, steps or stops.

We write the budget option first — the fewest pens that can honestly move the goal — and you upgrade at a check-in once the labs have earned it.

What it costs

The personal research protocol is €399, follow-up included: intake, human review, the three documents, the coach call, the check-ins and any revision when new labs arrive. No subscription.

Pens are not included: we do not sell, supply, source or ship any compound. The protocol lists the pens it assumes (300 clicks each). A recomposition cycle usually pairs a nightly pen with a second compound — two pens, confirmed by your coach on the first call.

Got an invite code or gift code from a coach? Enter it at the start of the intake and the protocol is on us — we are by invitation only, and the codes are how the invitation travels.

Frequently asked questions

Why does the scale not move on a recomposition protocol?

Because fat is leaving and muscle, water and glycogen are arriving at roughly the same rate. That is the design. If the waist is down 4–6 cm at week 12 and the scale is within 2 kg, it worked.

How long does body recomposition take?

Twelve weeks is the minimum honest cycle, and the mirror lags the tape. The waist usually starts moving around weeks 4–6; the visible change shows through weeks 8–12.

Should I do fat loss first and then build?

If you are more than roughly 10 kg from target, yes — faster and kinder with a dedicated fat-loss plan. Within 10 kg and in the mid body-fat range, recomposition saves you the bulk-and-cut cycle entirely.

Which compounds will my recomposition protocol use?

Usually a pairing: a mild appetite or visceral-fat compound and a nightly growth-hormone signal. Which pairing comes from your intake and baseline labs, not this page.

Can I run recomposition on a plant-based diet?

Yes, if you can hold 2 g of protein per kilo of target weight daily; the protocol writes the sources in. B12 and ferritin are added at baseline because they are the markers most often low on a plant-based intake.
