GRIN10 Essential Performance Stack

How to use each product

GRIN10 Whey Casein:

Add 1 scoop (32g) to 200–250ml of cold milk or water. Shake well in a shaker bottle for 15–20 seconds, or stir thoroughly with a spoon. Drink immediately.

For a thicker, more filling shake (recommended for pre-sleep and meal-bridge use), use milk. For lighter consumption or faster absorption, use water.

Vary the liquid quantity for desired taste and consistency.

Note: Whey Casein naturally forms a thicker shake than pure whey isolate. This is the casein gelling — the same property that gives you slow, sustained release of amino acids. If you stir with a spoon instead of using a shaker, you may notice a few clumps floating on top. That's not undissolved protein — it's the natural cocoa powder. A shaker bottle solves it in 15 seconds.

When to use:

1. For overnight muscle support – 30 minutes before bed. The slow-release casein feeds your muscles through the night when growth and repair peak.
2. For post-workout recovery (evening trainers) – Right after your workout, ideally within 30 minutes. The fast-absorbing whey covers immediate recovery, while the casein sustains amino acid supply until your next meal.
3. For long meal gaps – Whenever a gap of 4+ hours begins. Mix with milk and pair with a banana or some oats. Keeps you in a fed state without crashing your energy.
4. For rushed mornings – First thing on waking. Stops overnight catabolism and bridges you to your first proper meal, even if that meal is delayed.
5. For intermittent fasting – At the start of your eating window or as your last protein source before the fasting window begins. The sustained release helps you carry protein supply deeper into the fast.
6. For weight management – Between meals or as a meal-bridge when short on time. The slow-digesting casein keeps you full for 4–5 hours, controls hunger, and prevents overeating.
7. For late-night hunger – 30 minutes before bed instead of a snack. Satisfies hunger and supports recovery in one go.

GRIN10 Pre-workout:

When to use — your training day:

30–45 minutes before workout — 1 sachet Nitro focus in 300–400ml cold water. Wait for it to kick in, then start your warm-up.

Within 30 minutes after workout — 1 scoop Whey Isolate in 200–250ml water or milk. Covers immediate recovery and kick-starts muscle protein synthesis.

With your post-workout meal (or anytime that day) — 1 sachet ProCreatine in 200–300ml water. Taking it after food is preferable for absorption.

When to use — your rest day:

Skip the Nitro focus – Nitrofocus contains caffeine. Avoid it on rest days.Save it for training days only — this also helps prevent caffeine tolerance from building up.

1. Will NitroFocus keep me awake if I train in the evening?

NitroFocus has 150mg of caffeine — about the same as a strong cup of coffee. If you train in the evening, try to finish your NitroFocus at least 5–6 hours before bedtime so it doesn't affect your sleep. Your Whey Casein Blend shake after the workout is actually great for late training — the slow-release casein feeds your muscles through the night while you sleep.
