TWP All The Weight Up is where quality meets convenience—your mass gainer and meal-replacement (MRP) in one tub. Built on a base of whole-food carbs (gluten-free oats, sweet potato, quinoa, tapioca) and a multi-source protein blend (whey concentrate, milk proteins and hydrolysed egg white), it gives you clean calories that digest smoothly and actually support training. To round it out, you get a greens mix (spinach, broccoli, sprouts, kale, wheat grass), a vitamin & mineral complex, MCTs from coconut, a mushroom blend (Lion’s Mane, Chaga, Reishi) and a digestive enzyme complex—the details that turn a basic gainer into a genuinely useful daily tool.

Use it to push calories during a massing phase, as a between-meal shake when time is short, or as a balanced MRP on heavy days.

Key Benefits

• Real-food calories: Oats, sweet potato & quinoa for sustained energy—no sugar crash.

• 25 g complete protein per 100 g: Supports recovery and muscle growth.

• Greens + Vits & Mins: Everyday micronutrient support baked in.

• MCTs from coconut: Easily used fats for extra clean calories.

• Mushroom blend: Lion’s Mane, Chaga & Reishi—modern wellness staples.

• Digestive enzymes: Amylase, lipase & protease to help breakdown carbs, fats & proteins.

• Flexible: Use as a mass gainer or a meal-replacement—you choose.

How to Use

• Mass Gainer: Mix 100–150 g with 300–500 ml water or milk, 1–2× daily between meals.

• MRP: Mix 100 g with your preferred liquid for a balanced meal on the go.

• Tip: Start with 100 g and increase as needed to hit calorie targets. Shake hard, let sit 30–60 sec, then re-shake for a smoother texture.

Frequently Asked Questions

Is this a mass gainer or a meal replacement?
Both. The macros and ingredients work as a calorie-dense mass gainer, and the added greens, vits/mins, MCTs and enzymes make it suitable as a balanced MRP when you’re short on time.

What can I mix it with?
Water keeps calories lean; semi-skimmed or whole milk boosts calories and creaminess. It also blends well with yogurt or oats.

Does it contain added sugars?
Primary carbs are real-food sources (oats, sweet potato, quinoa, tapioca). Sweetness is from sucralose; no high-sugar syrups.

Lactose sensitive?
Contains dairy proteins. Many users tolerate it, but if lactose is an issue, try smaller portions with water or consider a lactase enzyme.

When should I take it?
Between meals, post-workout (if you want carbs + protein together), or any time you need quick, convenient nutrition.

Can I stack it?
Yes—pairs well with creatine, pre-workout, or omega-3s depending on your goals.
