Great customer service!!! It was my first order. It came & by mistake I was sent someone else’s order. At 5:30 in the evening I got an immediate response & a new tracking number & my correct order arrived within 2 days. Mistakes happen. It is what happens after the mistake that counts & Certified Peptides customer service sets the bar on how a mistake should be handled. So far I am happy with the products as well. I will order again for sure!!
