Who Is This For?
CBUM Itholate is for athletes who want the most macro-efficient protein available and don't want to guess at what's in it. The Informed Protein certification means the label is independently verified — 25g protein is actually 25g, not 22g with added amino spiking. The grass-fed isolate source appeals to athletes who care about where their food comes from, not just macros. At 0g fat, 1g carb, and 110 calories, it fits a cutting or recomposition phase without any padding. For Chris Bumstead fans and classic physique athletes, it's also the most direct way to fuel like the man himself.
Who Is This NOT For?
- ✗ Budget-focused buyers — at 25 servings per tub, this is a premium product; Allmax AllWhey Classic or Rule1 Whey Isolate offer more servings per dollar
- ✗ Hard-bulk athletes who need calorie density — at 110 cal/serving, this is built for leanness, not a surplus
- ✗ Vegans or vegetarians — dairy-derived whey protein isolate
- ✗ Anyone with severe dairy allergies — derived from milk
- ✗ Under 18 — not intended for use by minors
What's In It?
CBUM Itholate uses a single-source protein matrix: 100% micro-filtered grass-fed whey protein isolate. Micro-filtration is a cold-processing technique that preserves the natural protein fractions and removes excess fat, lactose, and carbohydrates without denaturing the protein through heat or chemicals. The result is a highly bioavailable isolate with a naturally rich amino acid profile. At 25g of protein per 110-calorie serving with 0g fat, it achieves an unusually high protein purity. Informed Protein certification means every batch is independently third-party tested — you can verify the certificate on the Informed Sport website by batch number. The formula contains no artificial growth hormones.
