  • Effortless calorie surplus: 620 kcal, 55 g protein and 80 g carbs in one shake to drive size and strength.
  • Quality mass, not just weight: fast-and-slow protein blend (whey concentrate, whey isolate, micellar casein) feeds muscles for hours.
  • Train harder, recover better: 3 g Creatine supports high‑intensity performance; 3 g L‑Glutamine supports post‑workout recovery.
  • Stay fuelled daily: complex carbs with 20+ vitamins and minerals to back demanding training schedules.
  • Great taste, great value: smooth chocolate flavour, easy mixability and 25 servings per 4.2 kg tub.

BSN True Mass All‑In‑One Gainer (Chocolate) — your high‑calorie, high‑protein mass gainer when eating enough is tough

Struggling to hit your daily calories between work, training and life? BSN True Mass All‑In‑One Gainer makes bulking simple. Each serving delivers a powerful 620 kcal with 55 g protein and 80 g carbohydrates so you can consistently reach a surplus, fuel performance and support muscle growth — without prepping an extra meal.

Inside is a clever protein matrix of whey concentrate, whey isolate and micellar casein. That combination gives you rapid post‑workout amino delivery and a longer release between meals — ideal for hard gainers and anyone chasing lean size. A balanced carb blend helps replenish glycogen for back‑to‑back sessions, while a broad spectrum of vitamins, minerals, taurine and black pepper extract rounds out your daily support.

Why lifters choose BSN True Mass All‑In‑One Gainer

  • All‑in‑one convenience: Calories, protein, carbs, 3 g Creatine and 3 g L‑Glutamine — sorted in one shake.
  • Performance support: Creatine helps increase physical performance in successive bursts of short‑term, high‑intensity exercise.
  • Recovery you can feel: L‑Glutamine is widely used by lifters to support post‑workout recovery and everyday training demands.
  • Seriously tasty: Smooth chocolate flavour with easy mixability — perfect when whole meals aren’t practical.
  • Built for consistency: 25 servings per 4.2 kg container to keep your bulking phase on track.

Who is it for?

Hard gainers, athletes in a bulking phase, and anyone who needs a reliable, great‑tasting way to increase daily calories without compromising protein quality. Use during strength cycles, hypertrophy blocks, team‑sport pre‑seasons or any time your training volume ramps up.

When to take your mass gainer

  • Post‑workout: Rebuild and refuel straight after intense training.
  • Between meals: Bridge the calorie gap and keep amino acids flowing for hours.
  • On busy days: A high‑calorie, high‑protein option when cooking or bigger meals aren’t realistic.

Pro tip for extra calories

Blend with milk, oats, banana or peanut butter to push your surplus higher — ideal for fast metabolisms and hard gainers. Use alongside a varied, balanced diet and structured training plan.

Directions for Use

To use, simply mix 3 heaped scoops (168g) in 600 ml of cold water. For optimal results, consume one serving immediately post-exercise or between meals to maximize your nutrition intake.
