加拿大采购需求：优替隆、吡咯烷、醋酸勃地酮、司坦唑醇、舒斯达农、生长激素

I'm looking to place an order for 10 packs of a specific medication in a 10mg dosage, including another product for shipment to Canada. It's important that the order meets quality standards and that the packaging is suitable for international shipping. Could you provide me with details on pricing, availability, and estimated shipping times? Additionally, I'd appreciate any information about customs regulations or documentation required for delivery to Canada. Looking forward to your prompt response so we can move forward with the order!
