I'm looking to source a weight gain powder, and I'd love more info on what your factory offers. Specifically, I'm interested in product formulations, available flavors, and any unique ingredients that set your products apart from others. Additionally, it would be great to know about your packaging options, sizing, and whether you have any certifications that ensure quality and safety. Also, could you provide details on your minimum order quantities, lead times for production, and pricing structures? Understanding your shipping options and costs would be helpful too. If possible, please share any samples or product specs that could aid in my decision-making process. Looking forward to hearing from you!
