# Bottled Protein Shakes CNP Brings Its 40g PRO-40 Formula To A Ready-To-Drink Milk-Based Shake By Ellen Smith | Written with AI assistance | Published 2026-10-18 | Lifestyle Source: Trend Hunter, https://www.trendhunter.com/trends/bottled-protein-shakes References: [stack3d](https://www.stack3d.com/2026/10/cnp-pro-40-protein-shake)  CNP is expanding its protein lineup with a ready-to-drink version of PRO-40, turning the product into a no-mixing option for people who want a bottle instead of a scoop. The half-liter drink uses a milk-based recipe and delivers 40g of protein in each serving. CNP sells PRO-40 through its own online store in cases of eight, giving regular users a stock-up format rather than a single grab-and-go purchase. Chocolate is one of the available flavors, keeping the drink close to familiar milkshake territory instead of pushing it into novelty territory. The 40g protein load widens what a ready-to-drink shake can replace, bringing bottled formats closer to a full powder serving. Direct online sales also let CNP fold the format into repeat supplement purchases instead of treating it only as an impulse convenience item.
