Testing & Certifications Explained

Metragenix currently has no certifications on record. This means there is no independent organization verifying the quality, purity, or safety of their products. The absence of certifications like NSF Certified for Sport or Informed-Sport means products are not tested for banned substances or contaminants by an independent entity. Consumers seeking third-party tested supplements should be aware of this.

Myprotein, with a trust score of 65/100 and Informed-Choice certification on some products, also demonstrates a higher level of third-party assurance than Metragenix.
