## Description

Serious Gainz from The Bulk Protein Company is one of our most popular protein powders and mass gainers.

Review: 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.
Review: OK, so first of all I will admit I should have read the nutritional content before purchasing this. Went looking for a protein powder, found this and thought....bargain! Only when it got delivered did I realise that it's aimed at those trying to gain weight. Not great for those trying to hit their protein while trying to keep to a calorie controlled diet. Unfortunately no return policy so figured I'd just use it and take the hit on the protein count for my breakfast shake. I now have regrets. This protein powder is just awful....gritty, tastes awful, and an hour after drinking it, I honestly feel a bit sick. I can't even imagine what this would be like with 3 scoops instead of 1. This stuff is the very definition of you get what you pay for. I will probably be throwing the rest in the bin. What a waste

## 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
- EXCELLENT VALUE 5kg TUB WITH 40 SERVINGS - With up to a month's supply of high quality protein powder, we offer great value for your money compared with other brands. We recommend one serving per day to consistently meet your daily protein goal. Consume immediately post-training on workout days and between breakfast and lunch on non-workout days.

*by L***M on 28 December 2025*

Cookies and cream tastes like play-doh 🤮 I will be adding milkshakes to alter flavour for me personally this time around, this brand is missing something with the flavouring compared to other brands just not as nice, so far had vanilla now cookies and cream, taste nothing like other brands, it was cheap so for that reason I'm rating 3 stars
