萨尔瓦多采购需求：益生菌、α-GPC、NMN、TUDCA、5a-羟基拉肖皂苷、刺槐豆胶

I'm reaching out to inquire about the availability of pharmaceutical-grade L-Glutathione for injectable use. We're looking to purchase 1KG for our production needs at Laboratorios PAILL in El Salvador. Could you please provide information on pricing, lead times, and any quality certifications you may have? We are eager to establish a reliable supply relationship and would appreciate your prompt response. Thanks!
