## Description

Product Description SERIOUS GAINZ by The Bulk Protein Company is a high-calorie mass gainer protein powder designed for hardgainers and anyone who struggles to eat enough to stay in a calorie surplus. Delivering approximately 468 calories, 30g of protein and 81g of carbohydrates per serving, it is positioned as one of the high calorie drinks for weight gain, helping support size, strength and steady progress during bulking phases. Each serving combines soy protein powder, whey isolate protein powder, casein protein powder and oat flour to provide both fast and sustained amino acid release, supporting muscle recovery, lean muscle growth and improved training performance. Formulated as a bulking protein powder, SERIOUS GAINZ can be mixed with water or milk, though many users prefer milk for a smoother, richer and more consistent texture. Adding liquid first, shaking thoroughly or using a blender helps reduce clumps and creates a creamier shake that is easier to drink during heavy bulking periods. Its naturally thick, dessert-style consistency can be customised to suit your preference—use more liquid for a lighter protein shake, blend with ice or fruit for added smoothness, or keep it dense for a more filling post-workout option. This flexibility allows you to tailor each serving to your taste, routine and daily calorie goals. SERIOUS GAINZ is designed to support consistency, helping you meet increased nutritional demands throughout your bulking journey. The balanced combination of protein sources and slow- and fast-digesting carbohydrates helps refuel muscles, restore glycogen levels and maintain high protein intake across the day. Available in popular flavours including Chocolate, Cookies & Cream, Vanilla, Strawberry and Banana, it offers a smooth, sweet flavour experience that fits naturally into shakes, oats, smoothies and high-calorie recipes. Ingredients Ultra-Fine OAT Flour, Ultra-Premium Maltodextrin, SOY Protein Isolate, Flavouring, Anti-Caking Agent (Silicon Dioxide), Whey (MILK) Protein Isolate, Casein (MILK) Protein, Whey (MILK) Protein Concentrate, Sweetener (Sucralose) P.when('A').execute(function(A) { A.on('a:expander:toggle_description:toggle:collapse', function(data) { window.scroll(0, data.expander.$expander[0].offsetTop-100); }); }); Directions Mix 3 Scoops (125g) with 400-500ML of water.

Review: Using it for years - Been using this product for years... Started at £25 about 7 years ago obviously due to British pound going down in value the price has risen. Still a good price. High carb shake with minimul sugars. I have bought similar products from Holland and Barrett and The sugar content is half the carb intake. I went from 10st to 17 on this in few years I have been taking. I bulk in winter and this helps... after a high calorie breakfast I also down one of these. People say it doesn't go well with water. No protein shakes you will ever take will taste well with water. I use 350ml water 250ml milk and it tastes good! I did a bulk last year I was 15.5st and went upto 18.5 by summer. I gained 1st extra in muscle. I went down to 16.5 off bulk and stayed at that weight even on The cut. I have around ,18% body fat. 22in winter. Also buy serious protein to add that extra 25g to the protein intake. 1.5-2g of protien per kg of body weight. If you not making gainz then you probably not doing this. This product has helped me a lot through out the years and I stand by serious protein and serious gainz to make my gainz.
Review: Pretty Good - Just started with Protein powder again after workouts. I’d used the Amfit stuff at first which was good but I thought I’d try a bigger Bulk tub. This was on offer with a further 10% off so a real bargain. Comes in the big black tub with snap seal and a scoop. Each scoop gives decent Carbs and Protein for your after workout/run nutrition. I got the strawberry flavour which is reasonably palatable, so of the powders are truly awful but this is pretty good. I have noticed if you make it up and leave it for a while it does develop a strange taste and texture so I tend to mix it up as I need it. It comes in various flavours which I haven’t tried but if they are the same as this one they will be good. I mix it with water, not tried milk but I would think it would be even better with Milk. All in all I’ll definitely buy again and at this price you can even double up if required.

## Features

- 30g PROTEIN PER SERVING TO HELP BUILD MUSCLE - Protein Isolate powder that contains 30 grams of high quality Protein per serving. A convenient and easy way to help you meet your daily protein needs. Use after training to quickly heal micro-tears in muscle tissues, which speeds up recovery, reduces muscle soreness and leads to stronger and bigger muscles over time
- PUT ON SIZE AND GAIN MASS - With 468 lean calories per serving, Serious Gainz protein powder is ideal when BULKING. Use as part of a balanced diet to help add body mass and increase weight gain. Contains 81g of carbohydrates which will help your body absorb the protein within, turning it into muscle mass to help towards improving your overall body composition
- PROTEIN SHAKE THAT TASTES GREAT - Add 3 scoops of powder to 400-500ml of water or milk and mix well to create a great tasting Protein Shake! Can also be enjoyed in smoothies, with oats or when added to a pancake mix. Protein powders don't have to be boring, so we made 10 different flavours for you to choose from
- HIGH QUALITY WHEY PROTEIN - Whey digests quickly and is rich in branched-chain amino acids (BCAAs). One of these BCAAs, Leucine, plays a major role in promoting muscle growth and recovery after resistance and endurance exercise. When amino acids are digested and absorbed into your bloodstream, they become available for muscle protein synthesis, which is the creation of new muscle

### ⭐⭐⭐⭐ Decent protein powder for the price
*by M***. on 5 May 2025*

Mixes well with no clumping, the cookies and cream taste is generally good, but there is a powdery gritty aftertaste which I'm not keen on. I can deal with it for the price as I can't afford the prices of the optimum nutrition protein powder now both me and my son are using it.
