It is "Whole body Cleanse" by Enzymatic. You can get it from the Vitamin Shoppe or on their website. Its on sale now for $17:99. I have tried it. I am currently taking it for the third time, but not consecutively. It will reduce it alot but do not completely eradicate it. I too smell like horse poops, fecal smell and skunk at times. But it been reduced now. Try to eat foods made by God only. More vegetables like kale and fruits, with very very little meat and chicken twice a week. Avoid fast foods and junk foods.
Good luck
