Muscle Protein Synthesis · Evidence-Based

4 PULSES.
Maximum synthesis.

Most athletes eat enough protein. Almost none eat it right. PULSE tracks your protein by MPS window — not just daily totals.

The Science

Your body can't store
unused protein.

Muscle protein synthesis (MPS) has a ceiling. Once triggered — typically by ~3–4g of leucine — it runs for around 2–3 hours and then shuts off, regardless of how much more protein you eat. The excess is simply oxidised for energy.

⚠ 1× MPS window — most protein wasted

PULSE ATHLETE — EVENLY SPREAD

✓ 4× MPS windows — protein fully utilised

MPS TRIGGERS PER MEAL

Each meal containing ~3–4g leucine (roughly 30–40g protein) triggers a full synthesis response lasting 2–3 hours.

THE CEILING EFFECT

Eating 80g in one sitting doesn't give you 2× the benefit. Beyond ~40–55g, additional protein is oxidised — not used for muscle repair or growth.

THE PULSE STRATEGY

Spacing 3–4 protein pulses of 30–50g across the day maximises total synthesis time and ensures every gram works harder.

LIVE MPS WINDOWS

Each pulse slot shows a live countdown of your current synthesis window. See exactly when it opens, peaks, and closes — and when to eat again.

📊

DISTRIBUTION SCORE

A 0–100 score showing how evenly your protein is spread. Optimal, Good, Uneven, or Poor — with a plain-English explanation of why.

⚠️

MPS CEILING ALERTS

PULSE flags when a single meal exceeds the ~55g MPS ceiling, so you know the excess protein isn't going to muscle.

FULL FOOD LIBRARY

Pulses, meat, and dairy — all with accurate protein-per-100g data. Log chicken, whey, lentils, eggs, skyr and more per slot.

Early Users

What athletes are saying.

"I was hitting 180g of protein a day and still not recovering well. Turns out I was eating 100g at dinner every night. PULSE showed me exactly what was wrong."

🏋️

MARCUS T.

Competitive powerlifter

"The MPS window countdown is a game changer. I now set a reminder when my lunch pulse closes so I never miss the next window."

🚴

SARAH L.

Endurance cyclist

"I use this with all my clients now. The distribution score gives me something concrete to coach against — not just 'eat more protein'."

Straight answers.

IS THE MPS SCIENCE LEGIT? ▼

Yes. The protein pulse model is based on peer-reviewed research, including work by Stuart Phillips (McMaster University) and Luc van Loon (Maastricht University) — two of the world's leading experts in protein metabolism and muscle physiology.

DOES IT WORK IF I EAT 3 MEALS? ▼

Absolutely. 3 evenly-spaced pulses still significantly outperforms loading most of your protein into one meal. PULSE will show your distribution score and flag if you'd benefit from a 4th pulse like a pre-bed snack (e.g. casein or cottage cheese).

HOW IS THIS DIFFERENT FROM MYFITNESSPAL? ▼

MyFitnessPal tracks totals. PULSE tracks timing and distribution — the part that actually determines how much of your protein gets used for muscle. Most athletes are already eating enough protein. Almost none are eating it at the right times.

CAN I USE IT AS A PERSONAL TRAINER? ▼

The Coach tier is built for this — manage up to 20 client profiles, set custom pulse plans, and share weekly reports. It's a genuine differentiator you can use to demonstrate evidence-based practice.

CAN I CANCEL ANYTIME? ▼

Yes, cancel from your account at any time with no fees or lock-in. If you're on an annual plan and cancel early, you keep access until the end of your billing period.
