  • 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.

Wow BSN always gets it right 👍

Have been using another pre-workout for the past two months. Came back to BSN and wow what a difference, such a good buzz for the gym. Sour cherry "red rush" isn't too bad to be honest, it's not overly sweet, miss fruit punch, but would like to try another flavour next time.

Had worse but also much better!

Day to day preworkout, nothing flashy, okay price, and about average buzz & itch. The taste is absolutely terrible (which is a shame as it smells amazing!). Would probably pick it over coffee.

Rocket fuel for your workout prep

Having tried plenty of pre-workouts over the years, this stuff is gold. BSN know their stuff, have been around for a long time and it's pretty comparable in value to other, far less effective PWO's.

Don't be fooled into thinking that this is just like drinking a coffee, it absolutely isn't and that quickly becomes apparent. Within about 10 minutes of drinking, your skin starts tingling from the beta-alanine and your energy levels quickly elevate to a point where it's almost impossible to not have the motivation to work out.

If I'm feeling particularly wiped or I know I'm going for a PR, sometimes I'll add a couple of extra grams over the recommended dose and it's very noticeable, just go a little careful as it does have caffeine in which can make you feel a bit jittery and the skin tingling can also get quite intense. Personally, I love the feeling but I appreciate that some people might find the sensation odd or unpleasant, and if that's the case then just dial it back.

I'm obviously not a doctor or nutritionist though so if you've not tried it before, then follow the label and start with the recommended dosage!

I've ploughed through many a PR with this as it just gives you that added boost you need to smash through your workouts and lift with the intensity you need for results, it also helps give you a nice pump if you're into that.

There is a slightly bitter edge to it which complements the sweetness of the berries, it's really quite tasty IMHO. Once you're all mixed and ready to go, I'd recommend knocking back the drink in order to experience the maximum effect, the recommended dilution is 13g in 200ml of water so it's pretty easy to down in one.

I have seen people use this as an intra-workout but personally I think it's a waste to sip it as you just don't get that hit of energy you want from the beginning.

It tends to start fading off after around an hour which is perfect and I've not had any issues sleeping providing you leave it a couple of hours before you hit the hay. Obviously this isn't a problem if you're into your morning training.

Morning, afternoon or evening, if you're flagging, demotivated or looking for that edge, this is the defacto standard of pre-workouts. Would thoroughly recommend.

⭐️⭐️⭐️⭐️⭐️ (5/5)

Let me start by saying this: if you're looking for a subtle energy boost, this ain't it. This powder will make you feel like you've been struck by lightning, chased by a pack of wolves, and injected with pure adrenaline—all at once.

I took one scoop, just one, and within 15 minutes I was ready to fight a bear. Not a regular bear, but one that had been to CrossFit for a few years and could deadlift a car. My arms started tingling like a thousand tiny ants were doing jazzercise under my skin. My ears were ringing, probably from the sheer intensity of my body's refusal to sit still.

By the time I got to the gym, I had already sweat through my shirt from walking to the car. I did bicep curls so fast, people thought I was attempting flight. I tried squats but ended up jumping into orbit. At one point, I considered running home because a treadmill just wasn't fast enough.

The flavor? Who knows. I don't remember. I think it was "Electric Fruit Punch," but honestly, it could've been battery acid and I wouldn't have noticed. My taste buds were too busy trying to survive the nuclear reactor I'd ingested.

Long story short: if you want to feel like a superhero who accidentally got hit with gamma rays and a shot of espresso, buy this. But buckle up, because there's no turning back.
