Previously bought single vials from EZP, decided I buy a kit from Nexaph since it's basically the same but most cost effective. Bought the kit of 60mg Triz and I'm super impressed with how quick the shipping was. Got the tracking number same day and received in hands within 2 days. Honestly, couldn't have been more happy. Plenty of testing from both Nexaph and 3rd party testers which definitely helps soothes the mind of those who just want a clean effective product.
