You may be a big believer in your favorite gun cleaning solvent—Hoppe’s, Break-Free, Gun Scrubber, etc. I’m here to tell you that I’ve yet to use one that works on a gun bore the way SUPREP does on the human gastrointestinal tract. The taste is appalling, like burnt, salty, black cherry stuff that was left on the stove for days. But, man, does it work. It kicked in 15 minutes after I drank it and is only now—2½ hours later—just thinking of letting up. I doubt there’s a gram of solid matter left in me. And I take a second dose tomorrow morning before "the procedure."
