Clean pre workout 300g at a glance
- Format: Powder
- Price: £27.99
- Who it is for: people who want caffeine and the two evidenced extras, without a proprietary blend
- What it is not: Clean pre workout 300g is a food supplement, not a medicine, and not an alternative to one.
Everything below sets out what clean pre workout 300g does, what may lawfully be claimed for it in Great Britain, and who should not bother. We would rather lose the sale than overstate it. The full clean pre workout 300g specification, price per serving and the alternatives worth considering are all further down this page.
Every ingredient is listed at its actual dose on the front of the tub, because a proprietary blend exists to hide how little of the expensive ingredients made it in.
Each serving provides 6g citrulline malate, 3.2g beta alanine, 2g creatine monohydrate, 200mg caffeine and 150mg L theanine.
Caffeine helps to increase alertness and helps to improve concentration.
The theanine is there to take the edge off the caffeine jitter, which is a combination most people notice immediately.
Take one scoop in 300ml of water twenty to thirty minutes before training.
The beta alanine will produce a tingling sensation on the skin.
That is harmless, expected, and wears off within the hour.
Not suitable for children or during pregnancy.

Clean Pre Workout 300g: before you buy
Clean Pre Workout 300g is stocked because every ingredient is listed at its actual dose on the front of the tub, because a proprietary blend exists to hide how little of the expensive ingredients made it in.

Compare it against the rest of our pre workout shelf, read what stimulants do and do not do, and see NHS guidance on vitamins and minerals.
Why this clean pre workout 300g in particular
Read the caffeine content first, because that is the ingredient with the largest effect and the one most likely to be over or under what you want. Then check whether citrulline and beta alanine appear at the doses used in research, since these are the two supporting ingredients with a real case.
Clean here means no proprietary blend, which is the single most useful thing a pre workout can offer. A blend lets a manufacturer list impressive ingredients without saying how much of each is present, and that is almost always because the interesting ones are there in trace amounts. A formula that publishes its doses can be assessed; one that does not, cannot.
What clean pre workout 300g actually does
A pre workout is a delivery vehicle for caffeine plus whichever supporting ingredients the manufacturer has chosen. Caffeine is doing the great majority of the work: it is well evidenced for performance across a range of activities and it is the reason you feel anything at all. The rest of the formula, typically citrulline, beta alanine and various nootropics, ranges from genuinely useful at proper doses to decorative at the doses commonly used.

How to take clean pre workout 300g
Add water to the shaker first, then the powder, then shake for longer than feels necessary. That order is the whole trick to a drink without lumps.
A powder lets you adjust the amount, which is genuinely useful when you are working out what suits you. Start at the lower end of the range on the label rather than the top.
Take twenty to thirty minutes before training. Note the caffeine content and avoid taking it within about six hours of bed.
How to read the label on clean pre workout 300g
The front of a label is marketing. The back is information. The percentage looks precise and is one of the least personal numbers on the panel.
The absolute amount per serving is the number that actually matters. Where a blend is listed as a single total, you cannot know the split, and that is the point of it.
Stacking clean pre workout 300g without doubling up
Before adding anything to this, one check saves more money than any discount code. The check takes a minute: list the actives in each product and look for overlap.
Duplication is usually harmless to the body and expensive to the wallet, but not always harmless. A short stack that you take consistently beats a long one you abandon in a month.
Who clean pre workout 300g is for, and who should skip it
A quick sorting exercise, because this is not a product with universal appeal. It earns its place for people who have checked they are actually short of something.
Not worth it for occasional trainers, whatever the label implies. The best outcome of this section is that some readers leave without buying.
What the evidence says about clean pre workout 300g
Here is where the research is solid and where it is thinner, stated plainly rather than selectively.
Caffeine has strong evidence for improving performance at around three to six milligrams per kilogram of bodyweight. Citrulline and beta alanine have reasonable evidence at proper doses. Most other pre workout ingredients have little support, and proprietary blends exist largely to obscure how much of each is present. A well formulated pre workout is caffeine, citrulline and beta alanine at honest doses; the rest is decoration.
What to expect from clean pre workout 300g, week by week
What follows is a timescale rather than a guarantee, which is the honest version. Week one is noise. Anything you notice is far more likely to be sleep, food or caffeine. If something is going to change, weeks four to eight is where it shows up.
Three months is long enough. Past that you are buying hope rather than an effect. Write down a number at the start, otherwise you are comparing against a memory.
What we can and cannot claim about clean pre workout 300g
What a supplement may claim in Great Britain is set by an authorised register, not by the seller. Here is exactly what may be said about this and what may not.
Caffeine carries authorised claims in Great Britain for contributing to increased alertness and to improved concentration, at specified intakes. There is no authorised claim for the other common pre workout ingredients, so nothing may be said about pump, focus beyond the caffeine claims, or performance generally.

Quality, testing and what you are trusting
The formula is rarely the differentiator here. Verification is. The published surveys of this industry are not reassuring, and pretending otherwise would be dishonest.
Under strict liability, what is in your body is your responsibility whatever the label said. If we cannot evidence something about a batch, the page says we cannot.
Ordering clean pre workout 300g: delivery and returns
Before the specification, the part people actually write in to ask about. Plain packaging is standard, not a checkbox you have to find at checkout. The arrival window is calculated at checkout rather than printed here as a slogan.
Sealed goods can go back within the statutory period, no reason required. We avoid printing next day promises on product pages, because that is the easiest claim in retail to get wrong.
Clean pre workout 300g: what you are actually buying
Twenty eight pounds for three hundred grams. The test of value here is the caffeine, citrulline and beta alanine amounts, all of which are stated rather than hidden.
The full specification sits below. Reduce everything to one serving before you compare, because pack size is chosen to make that hard.

Common mistakes with clean pre workout 300g
Most of the disappointment with this sort of product traces back to a short list of misunderstandings.
- Judging a pre workout by how much it makes you tingle, which is beta alanine and unrelated to effect
- Taking it late in the day, since caffeine has a half life of several hours and wrecks sleep
- Buying a proprietary blend, which is a way of not telling you how much of anything is present
None of those are unique to clean pre workout 300g, and all of them cost either money or the effect itself.

Clean pre workout 300g: common questions
What actually works in a pre workout?
Caffeine first, by a distance. Citrulline and beta alanine have reasonable evidence at proper doses. Most other ingredients are present in amounts too small to matter.
Why avoid proprietary blends?
Because they hide how much of each ingredient is present, which is generally the point of using one.
What actually works in a pre workout?
Caffeine, first and by a distance. Citrulline and beta alanine have reasonable evidence at proper doses. Most other ingredients are present in amounts too small to matter.
How late is too late to take one?
Caffeine has a half life of around five hours, so an evening dose is still substantially in your system at bedtime. If you train late, a stimulant free option is the sensible choice.
Is it worth taking every day or only on training days?
Take it consistently rather than around sessions. The physiology here works on weeks of average intake, not on what you did this afternoon.
How is it stored and how long does it keep?
A cool, dry cupboard out of the light. Read the period after opening as well as the expiry date, because for oils in particular those two numbers differ a lot.
How long before I notice anything?
It depends whether you were short to begin with. Correcting a real shortfall takes several weeks and usually shows up as the absence of a problem rather than a feeling.
Do you ship discreetly?
Every order. No branding, no product names, nothing on the label worth reading, and a billing descriptor to match.
Is more expensive always better?
No, and price is one of the least informative numbers on a supplement. Compare cost per serving against the dose that matters.
Can I open a capsule and mix the powder?
Generally fine. The exception is any capsule designed to survive the stomach or to mask a taste, and those say so on the pack.
Can I take this if I am pregnant or breastfeeding?
Ask a midwife or GP before starting anything. This is one of the few situations where the answer genuinely differs from the general population.
Is the packaging recyclable?
Tubs and most outer packaging are widely recycled, though pouches and tubs differ, so check the specific item. We are not going to overstate this, because the sector has a genuine problem here.
