I am interested in peptides GHK-cu, Semaglutide vials. What is your highest mg in these products? Please provide a price list for all of your peptides. I see that you have a 3-day delivery time. I would like to purchase these products today. Is there a shipping cost options? I have spent much time researching the products, prices, and the peptides I want to first purchase. I am looking for an ongoing relationship to purchase peptides from a company. I look forward to your reply.
