Verdict: A one-ingredient 5 g serving with a current U.S. NSF Certified for Sport listing. Strong verification and a clear label earn 91/100; the premium price remains the main objection. This is a public-evidence desk audit. ShreddedAF did not buy, handle or assay a retail unit.
Does this product solve a real problem for you?
Match the exact product
SKU KA57692P-315; 315 g unflavoured powder; approximately 60 servings; U.S. listing.
NSF Certified for Sport lists the unflavoured 315 g U.S. product, a 5 g serving and public lot numbers.
No-purchase option: if the need, identity or suitability is unresolved, pause. A strong product score is not a personal prescription.
The exact product and certification trail
This audit covers Klean Athlete Klean Creatine, SKU KA57692P-315, sold in the United States as a 315 g unflavoured powder. The official label states one approximately 5 g scoop, about 60 servings, 5 g creatine monohydrate and no other ingredients. That identity matters: a Canadian pack, a reformulated product or a seller listing without a matching label should not silently inherit this score.
The NSF Certified for Sport record identifies Klean Athlete Klean Creatine, country of sale United States, powder form, unflavoured, 315 g package and 5 g serving. It also publishes lot numbers. This is unusually useful because the certification evidence can be matched to product, market and lot rather than inferred from a brand logo. It still does not mean every marketplace listing is genuine or every unlisted lot is covered.
What the formula does—and what the premium does not do
Five grams of creatine monohydrate is a conventional daily amount and the formula avoids proprietary blends, sweeteners and added performance ingredients. That earns full formulation and transparency marks. The manufacturer recommends timing around training, but the practical priority is regular intake; the product page does not establish that a narrow timing window produces a superior result.
The premium buys a strong verification trail and convenient product identity. It does not buy a different creatine molecule. We found no head-to-head trial showing this product builds more muscle or strength than a cheaper, genuine monohydrate that supplies the same amount. Buyers who do not need sport certification should price that distinction honestly.
What the wider evidence supports
A 2025 systematic review and dose-response meta-analysis pooled 61 controlled trials of creatine combined with resistance training. It reported an average 1.39 kg increase in fat-free mass and 0.89 kg increase in body mass, with no significant average effect on fat mass, body-mass index or body-fat percentage. The review also found that the apparent difference between experienced and novice lifters was not statistically conclusive. Those pooled estimates describe varied research protocols; they do not promise an individual result and do not compare these brands.
A separate 2025 safety analysis examined reported effects across clinical trials and adverse-event records. It found that reported side-effect prevalence was generally similar between creatine and placebo groups. That is reassuring at the population level, but it does not erase product warnings, medication questions, pregnancy or nursing considerations, kidney conditions, or the need to assess an individual symptom. Product certification and clinical safety evidence answer different questions.
The practical default is simple: creatine monohydrate is the evidence-backed ingredient; consistency matters more than branding theatre. Loading can raise muscle stores faster, but it is optional. Someone already using a verified monohydrate does not need a second tub merely because another product ranks highly.
Our score: 91/100
The score separates formula, disclosure, exact-product evidence, safety information, company accountability and value. Certification earns evidence credit only for the product and market in its public record.
| Area | Finding | Score |
|---|---|---|
| Formulation | Single-ingredient creatine monohydrate at 5 g per serving | 25 / 25 |
| Transparency | Official label, SKU, net weight, serving and warnings are public | 20 / 20 |
| Exact-product verification | NSF product listing identifies U.S. pack, flavour, serving and lots | 18 / 20 |
| Safety | Warnings and allergen-positioning are visible; no individual suitability inference | 13 / 15 |
| Company accountability | Traceable brand, product file and certifier record; no customer-service test | 8 / 10 |
| Value | Clear price basis but expensive relative to plain monohydrate | 7 / 10 |
Value: calculate the price you actually pay
The observed official price was $34.50 for approximately 60 labelled servings when checked on 14 November 2026, equal to $0.58 before any extra delivery or taxes. This is a dated market snapshot, not a Cyprus quote or a promise that the price remains available. Subscriptions and multi-buy discounts are excluded from the base comparison because they add commitment and can change.
A premium may be rational for a strong certification trail, especially for tested athletes. It should still be visible. Compare delivered cost per 5 g of monohydrate, product identity and batch evidence. Do not compare cost per scoop when scoops contain different amounts.

Fit, alternatives and reasons to wait
Best fit: Athletes and serious recreational lifters who want a simple 5 g monohydrate serving with exact-product sport certification.
Look elsewhere when: The delivered price is high for a commodity ingredient, and certification does not make the powder physiologically superior to cheaper verified monohydrate.
Within the audited field, Thorne Creatine offers another sport-certified option, while NOW Sports Creatine provides a lower observed U.S. price and a public Informed Sport batch trail. These links are comparisons, not claims that one brand creates a better physiological response.
Buying nothing is sensible if training, protein intake, sleep or a medical question is the actual constraint; if an existing product already supplies verified monohydrate; or if the seller cannot show a matching market label. Do not stack two creatine powders for brand diversity.
What would change this verdict?
We will reassess after a label or serving change, certification or public-batch update, recall, discontinuation, identity problem or material value change. The next scheduled review is 14 December 2026. Awards, popularity, paid placement and affiliate performance cannot raise the score.
