If you bought raw shrimp, steam shrimp until pink, about 5 minutes, then cold shock under running water. Place in freezer until ready to serve.
Mix celery, horseradish, lemon juice, hot sauce, chili sauce, ketchup and vegetable juice together and season with salt and pepper. Pour sauce into 4 martini glasses and surround rim with chilled shrimp. Serve lemon wedges alongside glasses on cocktail forks.
