厄瓜多尔采购需求：Beufiller，1毫升注射器式唇部填充剂，1毫升唇部填充剂，1毫升下巴填充剂，1毫升下巴填充剂，肉毒杆菌毒素

I'm looking to purchase a specific quantity of botulinum toxin with a potency of 100U, and I'd like to explore pricing options for units at a cost of less than $15 each. My goal is to understand the minimum order quantity and any potential discounts for bulk purchases. Additionally, I would appreciate information on the product's availability and lead times for delivery. If possible, please include details about the quality assurance processes and any certifications your manufacturing facility holds. A prompt response would be great as I plan to move quickly on this procurement. Looking forward to your reply!
