The science behind Pürest Creatine™.
500 studies.
One conclusion.
Creatine monohydrate is the most studied performance supplement in existence. The science is not contested. What matters is purity, dose, and consistency. This page covers all three.

Published human studies on creatine monohydrate.
28d
Only 28 days to full muscle saturation at 5g daily. No need to load.
5g
The clinically established optimal daily dose.
Creatine monohydrate works by saturating your muscle phosphocreatine stores over time. It is not an acute stimulant. It does not have a meaningful peak or trough. It does not require timing around training. What matters is that it is present, consistently, at a sufficient concentration in your muscle tissue.
That concentration is reached through daily intake at the clinically validated dose of 5g. Not 3g — which is what most supplement brands use to extend tub lifespan at your expense. Not a loading phase of 20g — which saturates faster but delivers the identical long-term outcome, while benefiting your supplement brand's repurchase rate more than your performance. 5g, every day, for 28 days to reach saturation. Then 5g every day indefinitely to maintain it.
This is not a proprietary protocol. It is not a Alph8 claim. It is the conclusion of over 500 published peer-reviewed human studies conducted over more than 30 years. Pürest Creatine™ does not improve on the science. It simply delivers it without compromise.
The myth the industry relies on.
The loading phase benefits brandS.
Not you.
What brands tell you.
TAKE 20G FOR 5 DAYS.
Most supplement brands recommend a loading phase of 20g daily for 5–7 days. This saturates muscle stores faster. It also depletes your supply in approximately 3 weeks instead of 10. At 5g, a 300g supply lasts 60 days. At 20g, it lasts 15. The loading phase recommendation has a direct commercial benefit for brands.
What the research says.
5G DAILY.
SAME ENDPOINT.
The research is clear. A loading phase reaches full saturation in 5–7 days. 5g daily reaches the same saturation in 28 days. The long-term result — fully saturated muscle phosphocreatine stores — is identical. The only difference is how quickly you get there. 28 days is not a meaningful delay for a supplement taken indefinitely. There is no performance argument for the loading phase.
The ingredient standard.
German Creatine was the industry standard.
We went further.
German Creatine is a respected creatine monohydrate to a verified standard. It is legitimately among the better options on the market. We are not dismissing it.
Alph8's Purest Creatine™ goes further. 99.998% purity. 200 mesh particle size for complete solubility and no grit. Third-party verified by Mérieux Nutrisciences — not just at the source, but on the specific batch you are purchasing. That last point is the meaningful difference. It is the difference between a sourcing claim and a published proof.

The chemistry of purity.
Creatine isn't just creatine.
What's inside matters.
Every creatine monohydrate product contains more than just creatine. The manufacturing process generates a set of chemical by-products — impurities that accumulate in lower-grade ingredients and transfer directly into every serving you consume.
Most brands never test for these. Fewer still publish the results. Purest Creatine™ is independently verified by Mérieux Nutrisciences to deliver the lowest available levels of four critical impurities. Here is what they are, why they matter, and where Purest Creatine™ stands against the industry.
Creatinine is the primary degradation product of creatine. High levels mean a smaller effective dose reaching your muscles.
DCD indicates incomplete synthesis and poor manufacturing process control. Generic creatine averages more than double the EFSA limit.
A Cramer Class III suspected carcinogen. Generic creatine can exceed the EFSA limit several times over. Both Pürest Creatine™ and German creatine test at not detected.
Incomplete purification leaves cyanide traces in the final product. Pürest Creatine™ tests at completely non-detectable levels against a 100 mg/kg EFSA limit.
When you read "creatine monohydrate" on a label, you are not reading a purity claim, you are reading a category description. The actual purity of what is inside that tub depends entirely on the manufacturing standard of the source ingredient, the completeness of the synthesis reaction, and whether anyone has independently verified the result.
Alph8 uses NNB Pürest Creatine™ because the data shows it consistently delivers lower levels of every measurable impurity than alternative branded and generic creatines. The Mérieux Nutrisciences Purity Report (downloadable below) is batch-specific proof for the exact product you are buying. Download it, read it, and verify every figure above for yourself.

Why impurities matter at the doses that move the needle.
Beyond the muscle.
Your brain runs on
creatine too.
Physical output
Strength. Power. Recovery.
Creatine increases the rate of phosphocreatine resynthesis during recovery between high-intensity efforts. This translates directly to increased strength output, improved power in explosive movements, and reduced fatigue during repeated sprints or heavy sets.
The mechanism is not speculative. It is one of the most consistently replicated findings in sports science. The effect size is meaningful — typically a 5–15% improvement in maximal strength performance over the course of a supplementation period.
Cognitive output
Memory. Processing. Clarity.
The brain is an energy-intensive organ. It uses creatine as an energy buffer in exactly the same way muscle tissue does. Research into creatine supplementation and cognitive performance has found improvements in working memory and processing speed - particularly under conditions of sleep deprivation or mental fatigue.
Critically, the blood-brain barrier requires consistent sustained creatine supply to maintain elevated brain creatine levels. This reinforces the 5g daily protocol from a neurological perspective. Consistency is not optional. It is the mechanism.
The verification standard.
We test twice.
Most brands test once.
Most supplement brands test at the source - meaning the manufacturer provides a certificate confirming the ingredient meets specification. This is standard practice. It is also normally insufficient.
Alph8 uses what we call the Double-Lock. Purest Creatine™ is verified at the point of manufacture. Then we test again, independently, at Mérieux Nutrisciences - one of the most respected independent testing llaboratories in Europe. The batch you purchase has passed both tests. The results are published.
01 /
Sourced from NNB Nutrition
Pürest Creatine™ is produced to pharmaceutical-grade specification by NNB Nutrition - one of a small number of ingredient suppliers that operates at this standard. Lower levels of DCD, DHT, creatinine and cyanide than generic bulk creatine suppliers.
02 /
Verified at source
NNB Nutrition provides a Certificate of Analysis confirming purity, particle size, and heavy metal content for every production batch. 99.99% creatine monohydrate purity. 200 mesh particle size confirmed.
03 /
Tested again at Mérieux Nutrisciences
We send every batch to Mérieux Nutrisciences - an independent laboratory - for a second round of verification. This is the Alph8 Double-Lock. The results of this test are what you download as the Certificate of Analysis on the product page.
The exception in our ecosystem.
Every other Alph8 product is liquid.
This one isn't. Here's why.
The Alph8 Performance Ecosystem™ (Coming Soon) is built around liquid delivery. Faster absorption. No scooping. This is the correct format for the majority of performance ingredients — absorption speed, dissolution, and convenience are all meaningfully better in liquid form.
Creatine monohydrate is the exception. The reason is a chemical process called cyclisation. When creatine monohydrate is dissolved in liquid, it slowly converts into creatinine - a metabolic waste product with no performance benefit. The conversion rate is temperature and time dependent, but it is consistent and unavoidable.
A liquid creatine product that has been sitting in a bottle for weeks - or a ready-mixed pre-workout containing creatine - will deliver a meaningfully lower creatine dose than what is stated on the label. We do not do this. The creatine stays powder because the science demands it. Every other Alph8 product is liquid because the science supports it. We follow the evidence, not the aesthetic.
ZERO DEGRADATION. ZERO COMPROMISE.
