Viper is a great lab to order from and makes the process super easy. He has been running a sale which slowed down the T/A but that is expected with the high volume of orders. I believe this is my 5th time ordering from Viper and I have received everything. I used Bloods credit for my purchase and when I received my order I was missing 3 bottles of test. I instantly reached out and Viper shipped me the missing stuff with no issues free of charge. Great customer service and once again I am satisfied with my order. 10/10 recommend @viper-flex
