Mutant Mass Extreme 2500

Mutant Mass Extreme 2500 — 2450 Calories From Real Food Sources

Mutant Mass Extreme 2500 was built for hard gainers and seriously busy people who can't hit their daily calorie targets from food alone — delivering 2,450 calories and 92g of protein across two daily servings, all from quality real food ingredients. No vegetable creamers, no corn syrup solids, no unnecessary fillers. Just the cleanest mass gainer formula Mutant has ever made. Available in Vanilla Ice Cream, Triple Chocolate and Cookies & Cream, in stock at TopDog Nutrition.

Key Numbers (per 2 servings mixed with milk)

• 92g protein from 3 whey sources — Hydrolysed Whey Protein, Whey Protein Isolate and Whey Protein Concentrate, each with a different absorption rate to feed muscle at different stages of recovery.
• 2,450 calories — the surplus fuel that hard gainers actually need to grow.
• 512g carbs from real food — sweet potato and waxy maize, not cheap maltodextrin and corn syrup solids.
• 14g fat from quality plant sources — MCT oil (coconut), avocado and pumpkin seed for hormone function and cellular energy.
• Naturally occurring BCAAs, EAAs and glutamine — from the protein blend itself, not added separately.

Why Three Protein Sources?

Each whey source absorbs at a different rate. Hydrolysed whey is the fastest — it hits exhausted muscles immediately post-training. Whey Isolate follows. Whey Concentrate absorbs slowest, sustaining amino acid availability during the hours of recovery that follow. Together they create a sustained feeding window that single-source proteins can't match.

Why Real Food Carbs and Fats?

Most mass gainers fill their calorie count with cheap ingredients — corn syrup solids, vegetable creamers, maltodextrin. Mutant used sweet potato and waxy maize for the carbohydrate blend and MCT oil, avocado and pumpkin seed for the fat blend. The result is a calorie-dense product that fuels muscle protein synthesis and hormone function without the processing shortcut most competitors take.

Who Is This For?

• True hard gainers — fast metabolism, training consistently, scale not moving.
• Busy athletes — genuinely can't fit enough quality calories into the day.
• Bulking phases — when the goal is size and the priority is calorie surplus.

Directions

Start with 1 serving mixed with 360–600ml of water or milk to assess tolerance — the high calorie content can cause stomach discomfort if you're not used to large single-meal calorie loads. Once comfortable, work up to 2 servings daily: one post-workout, one between meals or before bedtime. For maximum benefit, mix with 1% milk rather than water. On rest days, take one serving in the morning and one in the afternoon.

Frequently Asked Questions

Is it suitable for lactose intolerance?

No — Mutant Mass Extreme 2500 contains whey protein concentrate, casein and milk proteins, all of which contain lactose. Not suitable for those with lactose intolerance.

Can I use it as a meal replacement?

In a pinch, yes — the quality protein, carb and fat profile means it's substantially better than skipping a meal entirely when you can't eat. Day-to-day though, it's designed to supplement meals, not replace them.

Does it contain creatine?

No — Mutant Mass Extreme 2500 is focused on protein, carbs and fats. For strength and power support alongside your mass-gaining phase, add a separate creatine product. See the full creatine range at TopDog.

How long does a 6lb tub last?

At 2 servings per day (the full daily protocol), a 6lb tub lasts approximately 10–12 days. Most serious users stock up — check if a larger size is available.

Which size should I buy?

At 2 servings per day, the 6lb lasts approximately 10–12 days — good for a first buy to confirm you tolerate the high calorie load and enjoy the flavour. The 12lb is the committed bulk buy, roughly 3–4 weeks of daily use at the full protocol and better value per serving. Once you know it works for you, the 12lb is the smarter purchase.
