No. If you look at the professional literature, "hcl" does not appear in the brand name "Wellbutrim XL" so it is apparently just part of the generic designation.
budeprion XL is a brand name of medication bupropion XL. Bupropion Hcl is a generic name & active ingredient present in budeprion XL, so both are same.
There is a drug pricing tool on most pharmacy websites. My guess is that it is very expensive though. I take it twice a day for a total of 300mg and it cost me $70 a month using Walgreens...
