Is Ascent or Klean Athlete better for athletes who get drug tested?

Both are NSF Certified for Sport, meaning every batch is tested for over 270 banned substances. Klean Athlete carries a slightly longer history of use among Olympic and NCAA athletes. Ascent is more widely available at mainstream retailers and runs cheaper per serving.

What does NSF Certified for Sport mean?

NSF Certified for Sport is the most rigorous third-party certification for sports supplements. It guarantees the product contains no banned substances, no undeclared ingredients, and is manufactured in a GMP-audited facility.

Is Klean Athlete worth the higher price?

For pro athletes or anyone tested under USADA, WADA or NCAA rules, the answer is yes. For recreational lifters, Ascent delivers the same NSF certification at a lower price.

Does Ascent contain artificial sweeteners?

No. Ascent is sweetened with monk fruit and stevia, with zero artificial sweeteners, colors or flavors.

What is native whey protein?

Native whey is extracted directly from raw milk via low-temperature filtration, rather than as a byproduct of cheese-making. Ascent uses native whey, which preserves more naturally occurring leucine and BCAAs than standard whey concentrate.

Is Klean Athlete grass fed?

Klean Athlete uses whey protein isolate without grass-fed sourcing claims. Ascent does not claim grass-fed either, but both brands focus on the absence of artificial additives, banned substances and proprietary blends.
