Potential drawbacks include the price point, which is higher than many standard whey proteins. The 25-serving size may require more frequent repurchases for heavy users. Also, the vanilla flavor, while pleasant, may not appeal to everyone. However, these are minor trade-offs for the quality and certifications offered.
