# Holiday Protein Powder Flavors Steel Brings Back Chocolate Peppermint Only for Its Whey-ISO By Adam Harrie | Written with AI assistance | Published 2026-11-13 | Lifestyle Source: Trend Hunter, https://www.trendhunter.com/trends/holiday-protein-powder-flavors References: [stack3d](https://www.stack3d.com/2026/11/steel-chocolate-peppermint-whey-iso)  Steel brought back its ‘Chocolate Peppermint Whey-ISO’ for the holiday season, giving protein powder users a winter flavor built around chocolate and candy cane rather than the brand’s earlier fall ‘Pumpkin Spice’ return. The release is made only for Whey-ISO, narrowing the seasonal offer to one powder. The flavor aims for a peppermint bark profile, pairing milk chocolate with a cooling mint note. Each serving packs 20g of protein, less than a gram of sugar and 110 calories. Tubs are available while supplies last at $40 for 25 servings. Steel shows how keeping Chocolate Peppermint exclusive to Whey-ISO can turn a holiday flavor into a more focused buy for people who already use that protein format, while a $40 price keeps a seasonal taste close to an everyday supplement purchase and helps limited flavors earn repeat use instead of a one-off novelty buy.
