Nutristat Pump Script

23 grams of 100% active glycerol in a liquid format, with S7 and sea salt. Stimulant-free, zero sugar, 30 servings in a 32oz bottle.

The glycerol dose here is not slightly higher than the competition — it is roughly seven times higher, and the arithmetic behind that is worth seeing.

Why 23g is not comparable to a powder's 5g

Powdered glycerol supplements use forms like HydroMax or GlycerPump. Both are glycerol bound to a carrier so it can exist as a stable powder — glycerol on its own is a syrupy liquid that attracts water from the air.

Those powders are typically 65% yield. So a product listing 5g of HydroMax delivers about 3.25g of actual glycerol; the rest is carrier.

Pump Script is liquid, so it needs no carrier at all — 23g listed is 23g of active glycerol.

Typical powdered pump product	5g HydroMax at 65%	≈3.25g active glycerol
Pump Script	23g liquid at 100%	23g active glycerol

That matters because the research on glycerol hyper-hydration uses doses in the region of 20g and above. A 3.25g dose is not a smaller version of the same effect; it is well below where the studies sit.

This is the same lesson as citrulline versus citrulline malate on our Thavage page — always check what the listed number actually yields.

⚠ Glycerol needs water. This is not optional.

If you take this wrong, it will not work — and it may make you feel unwell.

Glycerol is an osmolyte: it draws water into cells and holds it there. It does not create fluid, it relocates it. So the effect depends entirely on there being fluid available to move.

Nutristat's instruction is one cap into 32oz of fluid, sipped from 30 to 60 minutes before training and continued through the session. That is not a suggestion — the 32oz is part of the dose.

Taking 23g of glycerol in a normal 8oz pre-workout shake gives it very little water to work with, and concentrated glycerol on a relatively empty stomach can cause nausea and digestive discomfort.

Be well hydrated before you start. Sip rather than drinking it down. One serving per session, never more.

The sea salt is doing real work

110 to 125mg of sea salt looks like an afterthought. It is not.

Sodium is the primary extracellular electrolyte governing fluid balance, and it helps maintain the osmotic gradient that keeps water where glycerol has drawn it. Glycerol pulls fluid in; sodium helps it stay.

It is a small, cheap ingredient that meaningfully supports the main one, which is a sign of a formula built around a mechanism rather than a list.

S7 — a different route to nitric oxide

S7 is a blend of seven plant extracts — green coffee bean, green tea, turmeric, tart cherry, blueberry, broccoli and kale — at 50mg.

What makes it interesting is the mechanism. Citrulline and arginine work by supplying substrate for nitric oxide production. S7 instead appears to upregulate the enzyme, endothelial nitric oxide synthase, so your body produces more of its own NO rather than being given more raw material.

It also contains no nitrates, which means the mouthwash caveat that applies to GHOST Pump and Opti-Reds does not apply here.

Honest note on the "230% increase" figure. That comes from the ingredient manufacturer's own research, on a small sample. The mechanism is plausible and the dose is what was studied, but treat a headline percentage from supplier-funded research with appropriate caution. The glycerol is the reason to buy this product; S7 is a sensible addition.

How Pump Script differs from a powdered pump product

Main mechanism	Cell volumisation (water)	Nitric oxide (blood flow)
Glycerol	23g active	None in V2
Citrulline	None	6g

These are not competing products — they work on different mechanisms. Nitric oxide products widen blood vessels to increase flow. Glycerol pulls water into the muscle cell for fullness. They stack well, and if you want both, running the two together is a legitimate approach.

Who this is for

Who this is not for

If you will not drink the 32oz, do not buy it. The water is part of how the product works and skipping it wastes the glycerol and risks stomach discomfort.

If you dislike drinking large volumes during training, or find a full stomach uncomfortable under heavy sets, this format will not suit you.

Tested athletes should check the current WADA list. Glycerol has previously been classified as a prohibited plasma expander, and while its status has changed, anyone competing should verify against the current list rather than take our word for it.

Some people experience nausea or digestive discomfort with high-dose glycerol. Start well hydrated, sip slowly, and if it does not agree with you, it does not agree with you.

Frequently asked questions

Why is 23g of glycerol so much more than other products?
Powdered glycerol like HydroMax or GlycerPump is around 65% yield, so a 5g dose delivers roughly 3.25g of actual glycerol. Pump Script is liquid and needs no carrier, so 23g listed is 23g active — and research on glycerol hyper-hydration uses doses around 20g and above.

How much water do I need with it?
32oz. Nutristat's instruction is one cap into 32oz of fluid, sipped from 30 to 60 minutes before training. The water is part of the dose, not an afterthought.

How does glycerol work?
It is an osmolyte — it draws water into cells and holds it there, producing muscle fullness. It relocates fluid rather than creating it, which is why hydration matters so much.

What is S7?
A blend of seven plant extracts that appears to upregulate endothelial nitric oxide synthase, so your body produces more of its own nitric oxide — rather than supplying substrate the way citrulline does.

Does the mouthwash warning apply?
No. S7 contains no nitrates, so the oral bacteria step relevant to nitrate products does not apply here.

Can I stack it with a pre-workout?
Yes. It is stimulant-free and works on cell volumisation rather than nitric oxide, so there is no overlap with most pre-workouts.

Will it upset my stomach?
It can if you take it with too little water or too quickly. Start well hydrated, use the full 32oz, and sip rather than drink it down.

Can I take more than one serving?
No. One serving per training session.
