The Dose Makes the Pump

If you’ve shopped for a pump product lately, you’ve probably noticed something: there are a lot of them now.

That wasn’t always the case. Nutristat introduced Pump Script® as the first liquid glycerol muscle-cell volumizer, helping create an entire category of products built around hydration, vascularity, and the kind of pump that makes your sleeves reconsider their career choices.

Competition is good. It pushes everyone forward. But when formulas start looking alike from ten feet away, it pays to turn the bottle around and look at the part that actually matters: the dose.

Why Glycerol Dose Matters

Glycerol works by helping the body retain fluid and increase cellular hydration. For athletes, that can support hydration, endurance, muscle fullness, and the ability to keep performing when training gets demanding.

But putting “glycerol” on a label isn’t the same thing as delivering a meaningful amount of usable glycerol.

Many powdered glycerol ingredients are only partially glycerol by weight. Nutristat’s own comparison points to powdered alternatives providing up to 5g of material at roughly 65% yield, or about 3.25g of actual glycerol. Pump Script® delivers 23g of liquid glycerol at 100% yield per serving.

Even among other liquid glycerol competitors, the dosage is often lacking. Studies show that you need at least 20g of glycerol to achieve muscle cell hyper-saturation. If a pump product doesn't have that many grams per serving, then a "serving" is hardly a worthwhile measurement at all!

That difference is the whole point. If you’re buying a pump product for glycerol, you shouldn’t need a calculator, a second bottle, and a leap of faith to figure out how much glycerol you’re actually getting.

More Than a Big Number

Pump Script® isn’t just glycerol poured into a bottle. The formula pairs glycerol with premium sea salt to support hydration and fluid retention, plus S7™, a plant-based blend used to support the body’s nitric oxide response.

The goal is pretty straightforward: hydrate the muscle cell, support blood flow and nutrient delivery, and give serious training a formula with serious intent behind it.

Original Doesn’t Mean Untouchable

Being first is a nice piece of history. It isn’t a reason to stop improving.

What matters is that Pump Script® still earns its place by being transparent about what’s inside and how much you’re getting. Thirty servings. Twenty-three grams of glycerol per serving. A formula designed around the active dose instead of the marketing headline.

There are more choices in the pump category than ever, and that’s fine by us. Just compare the labels before you compare the promises.

Okay, that last sentence is absolutely not how percentages work. We know. Let us have this one.
