加拿大采购需求：活性药物成分、发酵产品、食品添加剂、原材料

I'm looking to place an order for a range of peptides and would like some more details. Specifically, I'm interested in understanding your available types, purity levels, and pricing. It would also be great to know your minimum order quantities and lead times for fulfillment. Additionally, if you have any recommendations for specific peptides that are popular or in high demand, please share those as well. I'm also curious about your packaging options and whether you provide sample sizes. This information will help me make an informed decision as we proceed with the order.
