I'm interested in understanding the pricing details for sulbutiamine. Can you provide me with the cost per kilogram? Additionally, I'd like to know about any bulk purchase discounts or special offers that might apply. If there are variations in pricing based on order quantities, please share that information as well. Also, it would be helpful to learn about your product's quality standards and lead times for shipping. Any details regarding packaging options or minimum order quantities would be appreciated too. Looking forward to your prompt response!
