No rBST. Milk & cream from cows not treated with the growth hormone rBST (No significant difference has been shown between milk from rBST treated and non-rBST treated cows). Chocolate ice cream and thick, creamy peanut butter swirls are wrapped in milk chocolate and crunchy, lightly salted pretzel pieces. We took a classic and created a new one. That's dazs.
