The customer service and shipping was…
The customer service and shipping was fine, but I do not trust the product. I switched from mounjaro to thier tirzeptide and it’s as if their product is nothing. A huge waste of money since I bought it in a larg batch to save money- an expensive lesson. Edit on 10/23/26- I'm coming back to add that my husband also used this product and neither of us had any noticeable effects from this product, following standard dosing. We bought a 10 pack so it was a significant purchase. I had reached out to the company about a month ago to ask for the COA as I had already been questioning the product and was told the COA is on the website and it's not linked to specific vials. Then after writing this review they reached out, but it was clear they didn't want to resolve the issue, it just seems they were frustrated I wrote this review. After some prompting, the only resolution they're willing to offer is "a few complimentary vials"....which I do not want more vials of a product that doesn't work.

We’re glad to hear that our customer service and shipping were satisfactory. We do want to clarify a few things. We have not received any prior communication from you regarding concerns with your order, so unfortunately, we were never given the opportunity to address your experience or help troubleshoot any potential issues. Product experiences can vary significantly based on several factors, and a comparison to a prescription medication like Mounjaro alone does not establish an issue with product quality. Additionally, your bulk order was placed less than three months ago, so we would appreciate the opportunity to better understand how you arrived at your assessment, as it takes longer than 3 months to use 10 vials and have a true assessment. Additionally, it is dependent on dose, diet, exercise, etc. We take product quality and customer satisfaction seriously and have thousands of satisfied customers who continue to trust our products. While we understand your frustration, we encourage customers to contact us directly when concerns arise rather than assume a product is ineffective without further evaluation. We would be happy to review your order, discuss your concerns, and provide any available product documentation. Please reach out to our support team so we can look into this further.
