INTERNATIONAL PROTEIN EXTREME MASS
Here's the listing: INTERNATIONAL PROTEIN EXTREME MASS Extreme Mass is International Protein's mid-range mass gainer — sitting between a standard protein powder and the full caloric density of Heavy Weight Mass Gainer. Where Heavy Weight is engineered for maximum caloric output per serve, Extreme Mass is built around a more balanced protein-to-carbohydrate ratio that suits athletes who want to add size and mass without the sheer volume of a 1,050-calorie serve. At 429 calories per 100g serve dry — or 674 calories mixed with 500ml of low-fat milk — it's a practical daily gainer that can be used two to three times throughout the day between meals. The standout feature of Extreme Mass is its five-source protein system, which delivers 42.5g of protein per 100g serve. Rather than relying on a single or dual protein source, International Protein has built a multi-phase absorption profile using five distinct sources that collectively ensure amino acids are available across an extended window — important for sustained nitrogen balance, which is central to the anabolic environment required for muscle growth. The five-source protein system includes Hydrolysed Whey Protein Isolate (the fastest-absorbing form, pre-digested into peptides for rapid uptake), High Glycomacropeptide WPI (a bioactive fraction of WPI rich in branched-chain amino acids and immune support compounds), Whey Protein Concentrate (a naturally rich source of immunoglobulins and growth factors alongside a strong amino acid profile), Calcium Caseinate (the slow-digesting dairy protein that sustains amino acid release for hours, supporting anti-catabolism between meals and overnight), and Egg Albumen (a complete, high-biological-value protein from egg white that complements the dairy sources with a distinct amino acid contribution and supports the overall nitrogen balance of the formula). The combination of these five sources across different absorption rates is what makes Extreme Mass a genuinely multi-phase product — it delivers fast aminos immediately via hydrolysed WPI, mid-range delivery from WPI and WPC, and a sustained release over several hours from casein and egg protein. MCT oils (2.8g per serve) are included as a dedicated fat source, providing medium chain triglycerides that are metabolised rapidly for energy rather than stored as body fat in the way longer-chain fatty acids can be. They add caloric density in a clean, fast-burning form that supports metabolic energy without contributing to unwanted fat accumulation. The carbohydrate sources include glucose for fast post-workout glycogen replenishment and rice starch — a non-allergenic complex carbohydrate that provides sustained energy release with a lower allergen burden than many other carbohydrate sources. Per serve (100g dry / with 500ml low-fat milk): 429 / 674 calories 42.5g / 62.5g protein 42.5g / 71.5g carbohydrates (9g / 38g sugars) 9.4g / 14.4g fat (2.8g MCT oils) 240mg / 940mg calcium (30% RDI dry) Only 1.7g lactose per dry serve Key features: Five-source protein system spanning fast, medium, and slow absorption 2.8g MCT oils per serve for clean caloric energy 42.5g protein per 100g serve Low lactose (1.7g per dry serve) 2025 NW Supplement Award — 3rd Best Weight Gainer 4.7 stars / 18 reviews / 94% recommend Available in 1.5kg and 4kg sizes, plus 4kg Multi-Flavour option Australian brand Flavours available: Chocolate Truffle, Strawberry, Choc Banana, Vanilla Ice Cream, Caramel Popcorn, Multi-Flavour (4kg only) Who is it for? Athletes and hard gainers who want a quality mass gainer they can use consistently two to three times per day as a caloric supplement alongside their regular diet. The five-source protein matrix and low lactose content make it a more digestible and nutritionally sophisticated option than many mass gainers in this calorie range, and the MCT oil inclusion supports clean energy without excess fat accumulation. Directions: Mix 100g (3 scoops) with 500ml of milk in a shaker or blender. Consume two to three times daily in addition to regular meals. Best taken mid-morning, mid-afternoon, and before sleep. Do not replace meals — use in addition to a complete diet. Warning: Not suitable for children under 15 years of age or pregnant women. Should only be used under medical or dietetic supervision. This product is not a sole source of nutrition and should be consumed in conjunction with a nutritious diet and an appropriate training or exercise programme.
