Redcon1 - MASS GAINER

1,270 Calories. 50g Protein. 256g Carbs. Built to Make You Bigger.

Redcon1 Mass Gainer is a high-calorie weight gain formula engineered for one purpose: putting athletes in a consistent caloric surplus. Hence, the body has the raw material it needs to build muscle mass. Every 5-scoop serving delivers 1,270 calories, 50 g of protein from a dual Whey concentrate and isolate blend, and 256g of fast-digesting carbohydrates — all in a milkshake texture that mixes clean and goes down easy. No gritty texture. No artificial thickness. No bloat-inducing ingredient list. Just calories, protein, carbohydrates, and taste — executed correctly.

If you train hard but struggle to grow, the problem is almost always the same: you are not eating enough. A consistent caloric surplus — consuming more calories than you expend — is the non-negotiable foundation of any muscle-building phase. For athletes with fast metabolisms, demanding schedules, or low appetite, hitting that surplus through whole food alone is genuinely difficult. Redcon1 Mass Gainer solves that problem in a single shake.

Who Redcon1 Mass Gainer Is Built For

Hard Gainers & Fast Metabolisms

Some athletes burn through calories faster than they can consume them. If you eat consistently but the scale refuses to move — or moves and then reverses within days — you are almost certainly not in a meaningful caloric surplus. Mass Gainer adds 1,270 calories in one glass, creating the surplus your metabolism demands without requiring another full meal to be prepared, cooked, and eaten.

High-Volume Athletes Who Need Glycogen Replenishment

Athletes running high training volume — multiple sessions per week, long workouts, sport-specific conditioning — deplete muscle glycogen rapidly. With 256g of fast-digesting carbohydrates per serving, Mass Gainer replenishes glycogen stores faster than whole-food carbohydrates, preparing muscles for the next training session sooner and more completely. This is particularly valuable for athletes training on back-to-back days.

Athletes in a Dedicated Mass Phase

A mass phase requires strategic, sustained caloric surplus over weeks — not just on training days. For athletes periodizing their nutrition, Mass Gainer provides a reliable, predictable caloric anchor that is easy to plan around: a fixed caloric load that scales up or down by scoop count, without re-calculating an entire meal plan.

Anyone Who Struggles to Eat Enough

Appetite suppression from stimulant pre-workouts, demanding work or school schedules, post-training nausea, and simple caloric fatigue from eating large volumes of solid food all contribute to under-eating in athletes who otherwise want to grow. A shake that replaces 1,270 calories of eating effort with 24oz of water and a blender bottle is a practical, sustainable solution — not a shortcut.

The Science Behind Mass Gaining

Caloric Surplus Is the Foundation of Muscle Growth

Muscle tissue cannot be synthesized without the energy required to build it. Research consistently demonstrates that muscle protein synthesis — the process by which the body constructs new muscle fibers — is significantly blunted in a caloric deficit, even when protein intake is adequate. The body prioritizes energy balance: when calories are insufficient, protein is redirected toward energy production rather than muscle construction. A sustained caloric surplus removes that constraint, allowing dieProteinotein to fulfill its primary structural role.

Why Carbohydrates Are the Primary Driver in a Mass Gainer

The 256g carbohydrate load — not the 50Proteinotein — accounts for the majority of Mass Gainer's 1,270 calories. This is intentional and correct. Carbohydrates are the body's preferred energy substrate: they fuel training intensity, drive insulin-mediated nutrient uptake into muscle cells, and spare protein from being oxidized for energy. In a mass-gaining context, high carbohydrate intake is not a liability — it is a feature. The higher the carbohydrate load, the more efficiently the body can use protein for its intended purpose: building muscle.

The Role of Maltodextrin in Post-Workout Recovery

Maltodextrin — the primary carbohydrate source in Redcon1 Mass Gainer — has a higher glycemic index than most whole food carbohydrate sources and a fast gastric emptying rate. In the post-workout window, this is an advantage: rapid glucose availability stimulates insulin release, which drives amino acids from the Whey protein blend into muscle cells and accelerates glycogen resynthesis. The combination of fast-digesting carbohydrates with fast-digesting Whey protein creates the most anabolically favorable nutritional environment of the entire day — and Mass Gainer is built specifically to exploit that window.

Why Whey Concentrate + Isolate Is the Right Protein Choice Here

Redcon1 Mass Gainer uses a blend of Whey Protein Concentrate (WPC) and Whey Protein Isolate (WPI) rather than a single source. WPI provides the fastest digestion rate and highest leucine density for immediate post-workout mTOR activation. At the same time, WPC contributes slightly slower digestion, naturally occurring immune-supportive immunoglobulins, and a richer Flavor profile that makes the product genuinely taste like a milkshake. The blend optimizes both the anabolic response and palatability — two factors that determine whether a mass gainer actually gets used consistently enough to produce results.

Scalable Dosing — Dial In Your Surplus

The 5-scoop full serving is a ceiling, not a requirement. Each scoop delivers approximately 254 calories, 10g of protein, and 51g of carbohydrates — giving athletes precise control over their daily caloric surplus without having to rebuild a meal plan.

How to Use

Mixing Instructions

• Add 5 scoops (334g) to 24oz of cold water or preferred beverage
• Shake in a blender bottle for 30–45 seconds, or blend for 15–20 seconds for maximum smoothness
• Consume immediately — maltodextrin-based shakes thicken as they sit
• For extra calories and a richer texture: replace water with whole milk to add ~150 calories, 8g protein, and 12g additional carbohydrates

When to Take It

• Post-workout (primary use): Consume within 30–60 minutes after training. Fast-digesting maltodextrin maximally exploits the post-workout anabolic window — replenishing glycogen and delivering amino acids when muscle uptake is highest.
• Between meals: A 2–3-scoop serving fills the caloric gap between breakfast and lunch, or between lunch and dinner — without additional food preparation. Ideal for athletes with demanding schedules or suppressed appetite.
• Before bed (advanced, optional): A 1–2 scoop serving adds 250–500 calories to the overnight recovery window. For optimal overnight results, pair with a slower-digesting protein such as casein or MRE Lite — the fast-digesting carbohydrate profile of Mass Gainer alone is not optimized for extended overnight release.

Sodium Awareness

At 852mg of sodium per full serving (37% DV), athletes monitoring daily sodium intake should factor this into their overall nutrition plan. For most athletes, this is not a concern — sodium supports electrolyte balance, muscle contraction, and nutrient transport. However, athletes stacking multiple sodium-containing supplements or following sodium-restricted protocols should adjust scoop count accordingly.

Mass Gainer vs. MRE — Which Is Right for You?

Redcon1 makes two high-calorie protein formulas. They serve fundamentally different purposes and phases of training — the right choice depends entirely on your goal.

Complete Your Mass Stack

Mass Gainer handles your caloric surplus. These additions cover the other pillars of an effective mass phase:

• Creatine Monohydrate — 5g daily replenishes intramuscular phosphocreatine, directly increasing strength, power output, and training volume — the three training variables that determine how much mass you add during a bulk. The most evidence-supported muscle-building supplement available.
• Redcon1 Grunt EAAs — All 9 essential amino acids (6.9g per scoop) for intra-workout muscle protein synthesis support. Use Grunt during training and Mass Gainer immediately after — a complete anabolic window protocol in two products.
• Redcon1 MRE — 47g whole food protein and 75g of complex carbohydrates from oats, sweet potato, and yams. Use Mass Gainer post-workout for the glycogen spike, and MRE as a mid-day meal replacement for sustained whole-food nutrition — a two-product system that covers both windows.
