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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe five-source protein system\u003c\/strong\u003e 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).\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMCT oils (2.8g per serve)\u003c\/strong\u003e 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe carbohydrate sources\u003c\/strong\u003e 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePer serve (100g dry \/ with 500ml low-fat milk):\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e429 \/ 674 calories\u003c\/li\u003e\n\u003cli\u003e42.5g \/ 62.5g protein\u003c\/li\u003e\n\u003cli\u003e42.5g \/ 71.5g carbohydrates (9g \/ 38g sugars)\u003c\/li\u003e\n\u003cli\u003e9.4g \/ 14.4g fat (2.8g MCT oils)\u003c\/li\u003e\n\u003cli\u003e240mg \/ 940mg calcium (30% RDI dry)\u003c\/li\u003e\n\u003cli\u003eOnly 1.7g lactose per dry serve\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eKey features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFive-source protein system spanning fast, medium, and slow absorption\u003c\/li\u003e\n\u003cli\u003e2.8g MCT oils per serve for clean caloric energy\u003c\/li\u003e\n\u003cli\u003e42.5g protein per 100g serve\u003c\/li\u003e\n\u003cli\u003eLow lactose (1.7g per dry serve)\u003c\/li\u003e\n\u003cli\u003e2025 NW Supplement Award — 3rd Best Weight Gainer\u003c\/li\u003e\n\u003cli\u003e4.7 stars \/ 18 reviews \/ 94% recommend\u003c\/li\u003e\n\u003cli\u003eAvailable in 1.5kg and 4kg sizes, plus 4kg Multi-Flavour option\u003c\/li\u003e\n\u003cli\u003eAustralian brand\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eFlavours available:\u003c\/strong\u003e Chocolate Truffle, Strawberry, Choc Banana, Vanilla Ice Cream, Caramel Popcorn, Multi-Flavour (4kg only)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWho is it for?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eAthletes 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.
