美国采购需求：当归粉、芹菜素、熊果苷粉、蒿甲醚片、青蒿素胶囊、青蒿素液

I am conducting a clinical trial for pediatric depression and am interested in your gummies containing thiamine. Could you share the pricing for the product, along with the possibility of obtaining a certificate of analysis? Additionally, I'd like to know if your manufacturing adheres to GMP standards. Your prompt response would be greatly appreciated as it would help in expediting our procurement process. Thank you!
