I have got to say that IBE labs has the highest and best customer service that I have ever seen in my life. I had a problem with my Viagra and Cialis not working, thought maybe it was underdosed, so I wrote to them and told them abou it. I got a responce back very quickly saying that they know it is not underdosed, but in any case they were going to send me 2 more bottles to replace the ones I had. They even sent it out the next day and sent it by express next day mail! Outstanding service. I will defientely be reccomending them to everyone I know, and will continue to by their products. Thanks IBE!
