Personally I steer away from deca, and I never use more of a designer compound than the actual test. Always run test higher and I avoid irritating sides, just my experience.. My brother uses BD, says its good but what research Ive done on the brand says its either produced before 05 or is illegitimate. That product was discontinued. Now he gets home brew from a heavy builder bud and swears by it. How long are you running the cycle? Good luck what ever you choose to do!
