I just noticed hem being on the web site where I didn't before. Considering you can buy all the products from FITX, DSN should be stocking them in time. I'll double check with DSN unless someone beats me to it this week.
This is the DSN guy on Regime so there is a history with SDN (Now owned by FITX) and DSN. I assume the Cenergy line will be carried as stated by DSN on Facebook. They have 8 US warehouses, multiple stores and online.
