I just want to post this as a compliment to Cain and Nexaph. I had 5 vials from the kit that had no vacuum at all. I was assured by Cain that there were no sterility issues and that 1 out of 3000 vials do not have a vacuum. Needless to say 50% of the kit not having a vacuum is a large statistical anomaly. The caps were not visibly damaged but definitely "askew" on the top of the vial and felt "loose" compared to other pep vials.
I did not use any of those vials. I have read on telegram that several others have had the same issue with the batch I received as well. After several emails with Cain he graciously gave me a credit and I am very grateful. Just wanted to post this here for information's sake about Nexaph. I will definitely be buying more from them in the future with no hesitancy.
