Serving size: 334 g
A high‑calorie mass‑gainer powder delivering 50 g protein, 250 g carbs, 6.3 g fat and a full suite of vitamins, minerals and 3 g creatine per serving, formulated for athletes seeking muscle and weight gain.
+ Very nutrient‑dense profile with a complete vitamin‑mineral complex and added creatine, supporting performance and recovery. + All ingredient doses are disclosed, offering full transparency. + Certified by Informed Sport and Informed Choice, meeting third‑party testing standards. + Larger pack sizes generally provide better value within the range.
- Contains milk and soy allergens, which may limit suitability for some users. - Includes soy‑based lecithin emulsifier and riboflavin colour, ingredients that are less common among peer mass‑gainers.
This product family stands out by pairing a substantial protein‑carb blend with a comprehensive micronutrient matrix and creatine, all in a single powder, a combination rarely seen in competing mass‑gainers. The formulation is consistent across flavours and sizes, with the only notable variant differences being the occasional flavour‑specific additives (e.g., cocoa powder in chocolate variants) and the presence of riboflavin colour and soy lecithin emulsifier, which are highlighted as rare inclusions. All variants share the same allergen profile and dose transparency, and larger packages tend to be more cost‑effective.
