Excellent customer service!!! Sarah has been assisting me with so many questions I have. She is wonderful and helpful. Shipping was fast as well. Today, I took my first shot of 10mg Tirz. I just switched from a Zepbound which was causing me $$$!!! And only lost 2 lbs in 4 months. I've read a lot of great reviews about this company and its products. So I decided to buy from them. Thank you so much. Highly recommended.
