Nutristat Pre Script
A pre-workout formula built around the three things a pre-workout should actually do: energy, blood flow and focus.
How to read any pre-workout label — including this one
Rather than repeat marketing at you, here is how to judge what is in the tub. It works on any product on any shelf.
1. Check whether the citrulline is pure or malate. This is the single most useful check, and it changes the numbers substantially.
| 6g citrulline malate | delivers about 4g actual citrulline |
| 8g citrulline malate | delivers about 5.3g |
| 6g pure L-citrulline | delivers 6g |
Citrulline malate is citrulline bonded to malic acid at roughly 2:1, so about a third of the weight is not citrulline. The researched range is 6 to 8 grams of actual citrulline — so a product listing "6g citrulline malate" sits below it. Full explanation on our L-Citrulline page.
2. Beta-alanine should be 3.2g. That is the clinical dose. Anything at 1.6g or 2g is a partial serving, and the tingle tells you nothing about whether it is working — that sensation is paraesthesia, and it fades with regular use.
3. Betaine should be 2.5g if present. Below that it is a label mention.
4. Check the caffeine, and count your day. The FDA cites 400mg daily as the figure for healthy adults, and that includes your coffee.
5. Look for a proprietary blend. If the actives are grouped into one total, you cannot run any of the checks above.
The three jobs, and what does each
Energy and focus: caffeine is the ingredient with by far the deepest evidence in sports nutrition — for power output, endurance and perceived exertion alike. Tyrosine supports it under stress and fatigue. L-theanine, if present, smooths the edge; the researched ratio is 1:2 theanine to caffeine.
Blood flow and pump: citrulline raises arginine more effectively than arginine itself does, because oral arginine is largely destroyed before absorption. Nitrate sources work through a separate pathway that bypasses the enzyme citrulline feeds — meaning the two are additive rather than duplicative.
Endurance: beta-alanine builds muscle carnosine, which buffers the acid that limits you in the 60-second to 4-minute range. It accumulates over four to six weeks, so it does nothing on the day you take it — timing is irrelevant and rest days count.
⚠ On stimulants and pumps working against each other
Worth knowing if you are choosing between products.
Caffeine is a vasoconstrictor. Citrulline is a vasodilator. They partially oppose one another, which is why a very high-stimulant product does not always produce the best pumps.
If pumps are your priority, a moderate-stimulant pre-workout with a separate stim-free pump product frequently works better than one very strong tub.
⚠ Caffeine tolerance is the real trap
The most useful thing we can tell anyone buying pre-workout.
Caffeine tolerance builds with regular exposure. If your daily driver is 400mg, within a few months you will need more than 400mg to feel the same thing — and there is very little above that which is sensible.
The way out is to keep your everyday product moderate and save the strong one for sessions that warrant it. That way the strong one still works when you reach for it.
Where it sits in our range
| Ignition Switch | 150 / 300mg | Most adjustable |

| MVPre 365 | 250mg | 10g citrulline, big nootropic stack |
| MVPre 3.0 | 350mg | Our long-running best seller |
| DEFY | 450mg | High stimulant, experienced users |
Come and ask us — our staff earn no commission, and matching a pre-workout to how much caffeine you already have in your day is the most useful thing we do at the counter.
How to take it
- 20 to 30 minutes before training, in 8 to 12oz of water.
- Start with half a scoop if it is new to you.
- Not within six hours of bed. Caffeine has a long half-life, and sleep matters more than the session.
- Take it consistently if the beta-alanine matters — carnosine builds over weeks.
- Do not stack it with another stimulant product.
- Take creatine separately unless the label includes it.
Who this is for
- Anyone wanting energy, pump and focus in one product
- People training in the morning or early afternoon
- Anyone who wants a formulated tub rather than assembling single ingredients
Who this is not for
Anyone training late in the evening — use a stimulant-free option instead.
Anyone caffeine sensitive, or already drinking several coffees a day.
Anyone who dislikes the beta-alanine tingle, if it carries a full 3.2g dose.
Anyone with high blood pressure, a heart condition or anxiety — speak to your doctor before using any stimulant pre-workout.
Tested athletes should check the full ingredient panel against their federation's list.
Not for anyone under 18, pregnant or nursing.
Stack it with: creatine, taken daily and separately.
Frequently asked questions
How do I judge a pre-workout label?
Check whether the citrulline is pure or malate, whether beta-alanine is at 3.2g, whether betaine is at 2.5g, what the caffeine total is, and whether anything is hidden in a proprietary blend.
What is the difference between pure citrulline and citrulline malate?
Malate is citrulline bonded to malic acid at roughly 2:1, so about a third of the weight is not citrulline. 8g of malate delivers around 5.3g of actual citrulline.
Why does it make me tingle?
Beta-alanine. That is paraesthesia — harmless, fades in about half an hour, and reduces with regular use. It is not a sign the product is working.
When should I take it?
20 to 30 minutes before training, and not within six hours of bed.
Can I take it every day?
You can, but caffeine tolerance builds. Keeping your everyday product moderate means a stronger one still works when you want it.
Do stimulants hurt my pump?
Partially. Caffeine is a vasoconstrictor and citrulline a vasodilator, so they oppose each other to a degree. If pumps are the priority, a moderate-stim product plus a separate pump product often works better.
Does it contain creatine?
Check the label. If not, take creatine separately and daily — including rest days.
How much caffeine is too much?
The FDA cites 400mg daily for healthy adults, and that includes coffee. Count everything.
