Addict Massive Weight Gainer (Strawberry - 5000 gr) - EXP 30/10/2026

What is Massive Mega Dose by Addict Sport Nutrition?

Massive Mega Dose is Addict Sport Nutrition's flagship ultra-caloric weight gainer, specifically engineered for hard gainers — individuals who struggle to gain weight and muscle mass despite eating regularly. With 1203 calories, 51g of protein and 240g of carbohydrates per 300g serving, it is one of the most calorie-dense gainer formulas available on the market, designed to push total daily caloric intake well above maintenance levels in a single convenient serving.

The protein matrix combines three forms of whey in a deliberate blend: whey protein concentrate (75%), which provides a broad amino acid profile and natural growth factors; whey protein isolate (15%), which adds a cleaner, faster-absorbing protein fraction; and hydrolysed whey protein (10%), which delivers pre-digested peptides for rapid availability. Together, they create a multi-phase protein release that sustains amino acid delivery over 1.5 to 3 hours, making Massive Mega Dose effective both immediately post-workout and as a caloric top-up between meals.

The carbohydrate base is maltodextrin — a fast-absorbing glucose polymer derived from starch with a high glycaemic index. This choice is intentional: for hard gainers, fast carbohydrates post-workout spike insulin, which drives both glucose and amino acids into muscle cells at the moment when anabolic sensitivity is highest. The near-zero sugar content (0.35g/100g) means the product's carbohydrate load comes almost entirely from maltodextrin rather than added sugars, which is a cleaner and more predictable fuel source for mass-gaining purposes.

Available in 2500g and 5000g formats across five indulgent flavours — Chocolate, Chocolate-Hazelnut, Snickers, Cookies and Vanilla — all sweetened exclusively with sucralose and containing no aspartame.

Mass without limits. Built for those who can't gain weight.
