Hello! I saw that you sell retatrutide at $1 per mg. I’m interested in purchasing 10 vials, each containing 10 mg. I’m not in a hurry to receive the shipment; slow shipping is perfectly fine because I dislike express delivery. Could you please tell me the payment methods? Looking forward to your reply, thank you!

你好！我看到你们销售瑞他鲁肽，每毫克价格是一美元。我对购买10瓶，每瓶10毫克感兴趣。我不着急收货，慢速运输完全没问题，因为我不喜欢快递方式。请问付款方式有哪些？期待您的回复，谢谢！
