I'm looking for detailed information regarding Soy Protein Isolate, specifically the different grades and formulations you offer. Could you provide me with your product specifications, including protein content, amino acid profile, and any certifications that might be relevant? Additionally, I'd appreciate it if you could share your packaging options and minimum order quantities. It would also be helpful to know your pricing structure and any potential discounts for bulk orders. If you offer samples, I'd like to evaluate the quality before making a larger commitment. Let me know about your lead times for orders and availability so we can explore a potential partnership. Thanks!
