The listed material uses polyphenol specifications. Review the analyte, reporting basis and differing grade descriptions below before requesting an EGCG-defined material.

Review 3 source-listing questions before selecting a grade
  • Specification: Listing fields contain different values; select the grade by written specification. Listed values: 0.5 / 50%,98%
  • Active ingredient: Source fields with the same name disagree. Listed values: Vitamin / Polyphenols
  • Appearance across source sections: The main attributes describe Brown powder while the archived detail table describes White Powder. Identify the offered grade and agreed appearance in writing; neither a photograph nor a colour description establishes its assay. Listed values: Brown powder (main Appearance field) / White Powder (supplier-detail Appearance field)

These source details need clarification and are not approved product specifications. Request a written clarification with the sample and COA.
