Dear Ms. Yang,

I am interested in purchasing three units of High Purity QSC Ly***** Research Peptide (Retatrutide) in 5mg, 10mg, or 15mg quantities.

I need all in all 20mg of retatrutide. 

Could you please provide the following details:

-Pricing and bulk order discounts
-Payment terms and accepted payment methods
-Estimated shipping time and costs to Regensburg, Germany
-Additionally, please confirm if you have relevant documentation such as COA (Certificate of Analysis) or MSDS (Material Safety Data Sheet).

Looking forward to your prompt response.

Best regards,
Leopold
