Whey Protein Isolate.

  • Found in : Grin10 Whey Protein Isolate
  • What it is : The protein fraction of milk, separated and filtered to remove most lactose, fat, and non-protein compounds. Whey isolate is typically 90%+ protein by weight — the highest protein density of any whey form.
  • Why we use it : Complete amino acid profile including all 9 essential amino acids. Fast-absorbing — reaches peak amino acid concentrations in the blood within 60–90 minutes of consumption. Richest natural source of leucine among common protein types, which is the primary activator of muscle protein synthesis (mTOR pathway).
  • Our dose : 30g per serving (delivers 26g protein)

Citrulline Malate

  • Found in: Grin10 Nitrofocus Pre-Workout
  • What it is: A combination of the amino acid L-citrulline and malic acid. Citrulline converts to arginine in the kidneys, increasing nitric oxide production. Nitric oxide dilates blood vessels, improving blood flow to working muscles.
  • Why we use it: Clinical research demonstrates improved pump, reduced muscle soreness (DOMS), and extended exercise capacity at the effective dose. Research consistently shows 6g as the minimum effective dose — many pre-workouts use 2–4g.
  • Our dose: 6g per serving

Creatine Monohydrate

  • Found in: Grin10 Creatine Monohydrate Plus
  • What it is: A naturally occurring compound found in small amounts in red meat and fish. Supplementation increases the phosphocreatine stores in muscle tissue, expanding the rapid energy reserve your muscles use for explosive efforts.
  • Why we use it: The most researched performance supplement in existence. 500+ peer-reviewed studies over 30+ years. Consistently shown to improve strength, power output, and muscle recovery. Safe for long-term daily use in healthy adults. Monohydrate is the form studied in the vast majority of this research.
  • Our dose: 3–5g per serving (clinical maintenance dose)

Caffeine Anhydrous

  • Found in: Grin10 Nitrofocus Pre-Workout
  • What it is: Dehydrated caffeine — a more concentrated, faster-absorbing form of caffeine than that found naturally in coffee or tea.
  • Why we use it: The most extensively studied performance-enhancing substance. At moderate doses, caffeine reduces perceived effort, improves reaction time, increases alertness, and extends time to exhaustion. We use 150mg — deliberate, effective, without excess.
  • Our dose: 150mg per serving

L- Theanine

  • Found in: Grin10 Nitrofocus Pre-Workout
  • What it is: An amino acid found naturally in green tea leaves. Not produced by the human body.
  • Why we use it: When combined with caffeine at a 1:1 ratio, L-theanine reduces caffeine's anxiogenic (anxiety-inducing) effects while preserving and enhancing its focus and alertness benefits. The result is clean, smooth energy without jitteriness or crash. This pairing is supported by multiple human clinical trials.
  • Our dose: 150mg per serving (1:1 ratio with caffeine)

L- Tyrosine

  • Found in: Grin10 Nitrofocus Pre-Workout
  • What it is: A non-essential amino acid that is the precursor to dopamine, adrenaline, and noradrenaline — neurotransmitters involved in focus, motivation, and the stress response.
  • Why we use it: Under conditions of physical and cognitive stress — like intense exercise — tyrosine depletion can impair mental performance. Supplementation has been shown to support cognitive function during stressful conditions. We use 2g — the dose used in cognitive performance studies.
  • Our dose: 2g per serving

Beta- Alanine

  • Found in: Grin10 Nitrofocus Pre-Workout
  • What it is: A non-essential amino acid that combines with histidine in muscle tissue to form carnosine — a buffer that neutralises the lactic acid build-up that contributes to muscle fatigue during high-intensity exercise.
  • Why we use it: At the clinical dose, beta-alanine supplementation increases muscle carnosine levels, extending time to fatigue during high-intensity efforts. Research shows 3.2g as the effective dose. Note: beta-alanine commonly causes a harmless tingling sensation (paraesthesia) at effective doses.
  • Our dose: 3.2g per serving

WHAT WE DON'T USE

Glycine, Taurine, Creatine (as hidden additives)

These amino acids can be used to inflate the total nitrogen content of a protein powder, making the protein percentage appear higher than it really is when measured by the Kjeldahl method. We don't use them for this purpose. Our 26g protein claim comes entirely from whey isolate protein — verified by third-party lab analysis.

Proprietary Blends

We list every ingredient with its individual dose. A proprietary blend lists a group of ingredients with a collective weight but no individual amounts — making it impossible to know if any ingredient is present at an effective dose. We don't use them because we believe you have a right to know what you're taking.

Artificial Sweeteners (in our Whey)

No aspartame, no sucralose, no acesulfame potassium. Our Whey Isolate is sweetened only with Stevia Leaf Extract — a natural, zero-calorie sweetener. Our Unflavoured variant contains no sweetener at all.

Banned Substances
None of our products contain substances prohibited by WADA (World Anti-Doping Agency) or listed as prohibited in any major sports federation's banned substance list.
