SERIOUS Gainz 2kg - Whey Protein Powder - Weight Gain, Mass Gainer - 30g Protein Powders - The Bulk Protein Company (Chocolate, 2kg) B09YVH9S2S
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.

Warrior Mass Gainer Protein Powder 5kg, 18 Servings – 1000 kcal High Calorie Weight Gainer with Whey & Casein – 61g Protein Shake Plus Glutamine – Muscle Growth Supplements – Double Chocolate B07R2CL9ZX
BUILT FOR SERIOUS WEIGHT GAIN – Each serving delivers around 1000 kcal, making this formula ideal for hard gainers and anyone struggling to consume enough calories through food alone. Developed as one of the most effective high calorie drinks for weight gain, it supports bulking and size goals with a dense, performance-focused formula. This is a reliable weight gainer for skinny people looking to increase daily calorie intake and support muscle mass. MULTI-SOURCE PROTEIN FOR MUSCLE GROWTH – Each serving of Warrior Protein Powder Mass Gainer provides 61g of protein from a carefully balanced blend of whey protein powder and micellar casein protein powder, delivering fast absorption after training alongside sustained amino acid release over time. This combination makes it ideal for daily protein shakes that help promote muscle growth, recovery, and maintenance, whether used post-workout or as a high-protein addition to your nutrition plan. HIGH-CALORIE CARB MATRIX WITH REAL OATS – Formulated with a carbohydrate-rich blend featuring fine milled oats, a real carb source that supports sustained energy release and glycogen replenishment during intense training. The inclusion of oats naturally creates a thicker texture and oat-based aroma, reflecting the high calorie density required for serious bulking and weight gain, not thin or lightly flavoured shakes. ENRICHED WITH GLUTAMINE FOR RECOVERY – Includes added glutamine to support post-training recovery, help reduce muscle breakdown, and contribute to normal immune function during intense training periods. Each serving combines fast and slow-digesting proteins with high calories to support sustained muscle recovery and performance between sessions. This balanced support makes the formula suitable for regular use during demanding bulking phases and as part of effective muscle building supplements. PREMIUM QUALITY ASSURED & EASY TO MIX – Manufactured in GMP-certified facilities and free from artificial colours and preservatives, ensuring consistent quality and reliability. Available in multiple flavours to suit your taste preferences, this bulking protein powder features a high-calorie, oat-based formula that is naturally thick. Best mixed with water or milk, or blended for a smoother consistency. Ideal for use post-workout or between meals to support daily calorie and high protein intake.
