INTERNATIONAL PROTEIN EXTREME MASS

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.

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.
