Quality 60 out of 100 · Mixed
Quality starts from 50 and nets to an indicative 60 after current NSF Certified for Sport positives are offset by old heavy-metal and spoilage incidents. The current athlete-safety testing signal is real, but public COAs, current NSF GMP facility verification, and batch-level contaminant results were not found in this audit.1,5,6,20,23
Not scored: No public batch COA portal, ISO 17025 lab scope, complete manufacturing-site list, or current public contaminant-testing panel was found. The audit verified sampled NSF product listings but did not exhaustively enumerate every SKU and lot.
How this score was built
Starts at 50, ends at 60.
- +9 NSF Certified for Sport coverage across powder portfolio 1,2,3,4,5 Current as of 2026 official and NSF directory pages. Pattern calculation: PepsiCo states all Muscle Milk powder products are NSF Certified for Sport, and sampled NSF listings confirm Genuine Protein Powder, 100% Whey, and Pro Series Creatine. Because this appears broad for powders but not the full ready-to-drink portfolio, I applied 90% of the +10 upper value, rounded to +9. · full weight
- +8 Third-party testing disclosed through NSF Certified for Sport 5,7,8 Current product pages. NSF screening is disclosed, but product-level COAs and full contaminant panels are not public, so this uses the low end of the +8 to +12 range. · full weight
- −5 Historical independent heavy-metal concern in protein products 20,21,22 2010 to 2012, more than 10 years ago. Base contamination quality concern selected at -20 because Consumer Reports and related litigation concerned heavy metals, then discounted 25% for age: -20 x 0.25 = -5. · 25% weight
- −2 Historical voluntary spoilage recall affecting Muscle Milk drinks 23,24 June 2016, slightly more than 10 years ago as of 2026-07-01. Base minor voluntary recall quality penalty selected at -8 because it was a packaging spoilage issue with no reported illnesses, then discounted 25%: -8 x 0.25 = -2. · 25% weight
