尼泊尔采购需求：人用肽，GMP认证肽

I'm reaching out to inquire about your offerings related to the color "black." We're particularly interested in various products that feature this color, as it aligns with our current collection needs. Could you provide details on the available items in black, including specifications, pricing, and any minimum order quantities? Additionally, it would be great to know about lead times and shipping options. Looking forward to your response!
