Product Description

What is Tri-Mass?

Tri-Mass is a premium Mass Gainer designed for those looking to transform their physique and pile on muscle while avoiding excess body fat. Each standard 130g serving contains over 500 calories and is packed with over 30g of premium quality protein and 80g of complex carbohydrates. However, if you’re not too concerned with leaner gains, or struggle to put on weight, you can always try the ‘Hard Gains’ serving. This mammoth shake gives you over 1000 calories and 60g of quality protein. Tri-Mass contains both slow and fast absorbing proteins , making it ideal straight after a workout and as daily supplement to increase calories. It’s exceptionally blended, instantised for easy mixing, contains only the finest ingredients and tastes fantastic. We’re confident that Tri-mass is one of the highest quality and best value mass gainers available in the UK.

Unique Time Release Protein Blend

One of the things that makes Tri-Mass unique is its protein composition and unique time release design. Unlike many mass Gainers, Tri-Mass maximises protein uptake by combining three quality proteins from different sources. This means that as well as providing the body with a protein that’s rapidly absorbed (perfect for after a workout or first thing in the morning), Tri-Mass provides a steady flow of protein that’s trickled to the muscle over a sustained period of time. This is essential for maximising results, muscle growth and recovery.

Complex Carbohydrate Blend

You might want to put on size, but chances are you probably want to avoid a belly that jiggles. A lot of mass gainers are high in calories because they’re packed full of cheap additives, fats and simple sugary carbs. This isn’t the case with Tri-Mass. Tri-Mass uses a bespoke Complex Carbohydrate blend that’s high in lean carbohydrates and low in sugars and fat. This blend of maltodextrin oats and waxy maize starch will insure that you get a sustained release of energy and is perfect for fueling hard training and replenishing energy stores.

Accelerated Gains

If you really want to pile on size fast, aren’t too concerned with leaner gains or really struggle putting on weight (damn that metabolism!), you can use Tri-Mass’s 260g Hard Gains serving. This will give you a whopping 60g of premium protein, 160g of complex carbohydrates and over 1000 calories. If you combine this with sound nutrition and a rigorous training programme, you should see significant changes in your body in no time.

When should I take Tri-Mass?

Tri-Mass can be taken straight after a workout, first thing in the morning or between meals to boost your daily calorie intake.

2kg Powder, 4kg Powder

Suggested Use

Depending on your training goals, we offer 2 serving suggestions. Normal use for slower increases in body weight, and Hard Gains for dramatic body transformation.

Normal Use (30 Servings per 4kg Pouch): Blend 3 level scoops (130g) with 300ml of water or skimmed milk. This will give you over 500 calories, 30 grams of protein and 80 grams of complex carbs. Consume twice per day, once with breakfast and once after a workout. On non-training days, we recommend having your second shake between lunch and dinner.

Hard Gains (15 Servings per 4kg Pouch): Blend 6 level scoops (260g) with 400ml of water or skimmed milk. This will give you over 1000 calories, 60 grams of protein and 160 grams of complex carbs. If you struggle to put on weight or are simply looking to maximise your gains then this serving is for you. Consume twice per day, once with breakfast and once after a workout. On non-training days, have a second shake between lunch and dinner. Please note, we recommend trying the 130g serving size for a while before jumping straight into the 260g – a sudden 2000 calorie jump might catch your stomach a bit off guard. Not fussed? Okay, but don’t say we didn’t warn you!

    Good value, mixes well (no lumps!) and tastes good. I’m really impressed with this product. Have tried other mass gainers in the past and they’ve been either too thick, too sweet or the texture has just been horrid.

    Too early to comment on the results, but if it works as well as it tastes then I’ll be very happy.
