Review of Certified

Review of Certified by Maria
Hi Jason, I’d like to share some honest and constructive feedback with the intention of helping your company continue to improve. I’ve recently started using your peptides, and overall I appreciate the opportunity to work with your products. That said, I’ve noticed a few issues I wanted to bring to your attention: Some of the labels are larger than the vials, and a few are not well adhered. During shipping, the labels can shift or peel, which makes the product appear less professional and not as new. Shipping times have been longer than expected. The vial caps are extremely difficult to remove when preparing the product. In some cases, I’ve had to use tools like forceps to open them, which is not ideal—especially when preparing medication in front of patients. I’ve also noticed that the NAD+ vials appear wet inside. I’ve ordered NAD from other companies before and have not seen this, so it raised some concerns for me. Additionally, I recommended your company to a colleague, and unfortunately their package appears to have been lost. I’m sharing this feedback transparently and respectfully, with the genuine intention of helping improve the overall experience and presentation of your products. Thank you for the opportunity to provide this input, and I hope it’s helpful. Best regards, Dr. Maria Quiroz
