美国采购需求：乳清蛋白、豌豆蛋白、大米蛋白、氨基酸、乳清分离粉、氨基酸片

I'm interested in your products and would like to request a tiered pricing structure for one of your offerings. Specifically, could you provide me with the prices for quantities of 50 kg, 500 kg, and 1000 kg? Understanding the price breaks for these quantities will help us make a more informed purchasing decision. If there are any additional details or bulk order discounts available, please include that information as well. Looking forward to your prompt response!
