USN Hyperbolic Mass GH 4KG

USN Hyperbolic Mass gH 4KG — Bulk Size, Best Value Per Serve

The same all-in-one mass gainer in the size that makes daily use affordable. Up to roughly 1,178 calories and 60g of protein per full serve, from a multi-stage Glyco-Matrix carbohydrate system and a six-phase protein blend. 4KG. In stock at TopDog Nutrition.

The Numbers

A full serve delivers up to roughly 1,178 calories and 60g of protein. That's a substantial addition on top of whatever you're already eating, and it's the reason the product exists.

Gaining weight is a calorie surplus problem, and for some people it's genuinely hard. Fast metabolism, physical job, or an appetite that gives out before your target does. Eating 4,000 calories a day of whole food is a full-time job, and chewing becomes the bottleneck.

A gainer solves exactly that, and nothing else. If you can hit a surplus with food, do that instead — it's cheaper and more nutritious. This is what goes on top when eating isn't enough.

The Glyco-Matrix Carbohydrate System

The carbohydrate side uses a multi-stage system rather than a single source, and the reasoning holds up.

Fast-digesting carbohydrates raise blood glucose and insulin quickly, which drives amino acid uptake into muscle and starts glycogen replenishment immediately. Slower-digesting sources extend energy availability over hours instead of producing a spike and a crash.

Combining them means the shake works both as immediate post-training recovery fuel and as a sustained calorie source between meals.

Six-Phase Protein Blend

Sixty grams of protein from six sources with different digestion speeds. Fast fractions spike amino acids for the immediate post-training window; slower fractions extend availability across several hours.

That matters more in a gainer than in a standard protein. You're often taking it between meals as a calorie top-up rather than around training, and a sustained release fits that use far better than a fast protein would.

Why the 4KG Size

Gainers are consumed faster than any other supplement category, and cost per serve is what determines whether you actually stay in a surplus or start rationing it.

The 4KG roughly doubles what you get from the 2KG at a materially better rate per serve. It's the right buy once you know the flavour suits you and you're committed to a building phase.

If you haven't used a gainer before, start with the 2KG. Four kilos of a flavour you don't enjoy drinking daily is a long, unpleasant tub.

Storage matters at this size. Keep it cool, dry and sealed, since moisture causes clumping and shortens shelf life.

Directions — Start Small

Blend one serve with water as directed. Use a blender rather than a shaker; this is a large volume of powder and it mixes considerably better with a blade.

Start on a half serve for the first week or two. Close to 1,200 calories in one sitting is a lot for a digestive system that isn't used to it, and going straight to a full dose usually ends in feeling bloated and skipping the next one. Build up as your digestion adapts.

Take it between meals or after training. A gainer goes on top of eating properly, not instead of it.

Frequently Asked Questions

Will it just make me fat?

It will make you gain weight, which is the point. How much is muscle versus fat depends on your training and how aggressive the surplus is. Around 0.25 to 0.5kg a week is a sensible rate for gaining mostly muscle. If you're gaining faster than that, halve the serve.

Can I take half a serve?

Yes, and most people should start there. Half still gives roughly 590 calories and 30g of protein, which is a serious addition on its own.

Do I need a separate protein powder?

Not on the days you use this. Sixty grams is a large protein dose. On non-gainer days a standard protein is the cheaper way to hit your target.

When should I take it?

Between meals is the most useful slot, since that's where the calorie gap usually sits. Post-training also works well given the carbohydrate content.

Is the formula the same as the 2KG?

Identical. Same calories, same protein, same blend. Only the tub size and the price per serve change.
