Revised Review - I initially bought two 30 mg vials of tirzepatide from the company in September. My previous review mentioned that I felt the potency was not as strong as other vendors I had used. In November, their customer support team contacted me after noticing my review. They acknowledged the quality concern and informed me about the improvements made. They offered to send me one 30 mg replacement vial—half of my original order—to showcase the enhanced quality and requested that I update my review if I noticed an improvement. The replacement arrived within a few days of our communication, and the quality was significantly better this time. I truly value when a company takes steps to resolve an issue, and the company followed through. I’m giving four stars because, while they didn’t replace both vials from my original order, the enhancement in product quality and their proactive approach deserve commendation.
