    We’re so sorry your package is taking longer than expected Saima! We processed and packed your order within 48 hours of receiving it because you ordered on a Saturday and we don’t ship on Sundays. Unfortunately once it leaves our facility we have no control over the USPS system which is why we provide tracking information for all our orders. I apologize for the inconvenience, it’s frustrating for us as well, please let us know when you receive your package.

    I am amazed and pleasantly impressed with the level of professionalism and how personal the owner was. During our email correspondence during Thanksgiving day, I felt like I’ve known her for years. I felt that I was in good hands and could trust Danielle and the products she offered. That’s VERY important to me. When the products arrived… WOW!!!! They were adequately protected and properly insulated. And, there was the absolutely adorable protective case with the products tucked safely in place. I wish I could share pictures.? Advanced Research Peptide has my business… end of discussion.
