Why CR8

Check what is actually in your creatine.

Creatine is one of the most researched supplements in sport. But over the last two years, independent labs kept finding the same problem with the trendiest way of taking it: gummies containing a fraction of the creatine on the label. CR8 exists to be the opposite of that. One ingredient, a measurable 5g dose, and the lab report published on this site.

Why does this keep happening to gummies?

Chemistry. Creatine is unstable in moist, acidic formats and gradually converts into creatinine, a breakdown product that does nothing for performance. As a dry powder it stays stable for years. That is why CR8 is a powder.

The dose is the whole point

The authorised UK performance claim for creatine applies only at a daily intake of 3g. Several of the tested gummies could not deliver that at any realistic serving. One 5g scoop of CR8 clears it with room to spare, and you can check the lab report below.

We have not commissioned testing of other brands ourselves. The findings above come from the independent third-party sources linked. CR8's own certificate of analysis is published on this site.

The story

Why I made CR8.

I've taken creatine for years. Eighteen months ago, independent lab tests started exposing creatine products that contained a fraction of what their labels promised, some with none at all. The brand sitting in my cupboard appeared in those published results.

That sent me down a rabbit hole. The UK supplement space is far less regulated than most people assume. It is entirely possible to sell a product that doesn't contain what it advertises.

I looked at making gummies first, but I couldn't find a single manufacturer I trusted to deliver the creatine as advertised. And the chemistry is against them: creatine degrades in moist, acidic formats.

So I went the powder route, found the most credible UK manufacturer I could, and kept it simple. One ingredient. A 5g dose you can measure. A lab report you can read on this site.

CR8 is the creatine I wanted to buy and couldn't find.

What creatine is actually allowed to claim.

Creatine increases physical performance in successive bursts of short-term, high-intensity exercise.

The beneficial effect is obtained with a daily intake of 3g of creatine. Intended for adults performing high-intensity exercise.

Why powder

Simple by design.

CR8 uses a straightforward powder format so the serving is clear, the formula stays simple and the product is easy to add to your daily routine.

A dose you can measure
Stable for years, not weeks
No unnecessary blends
One active ingredient
