by Quest · Budget whey/casein blend

Whey/casein blend, ~23-24 g protein, low sugar. Budget-friendly and easy to find; flavors are sweeter than the premium isolates.
23g per scoop, whey + milk protein isolate, widely available. Contains sucralose. Chosen by some GLP-1 users specifically because the slower-digesting casein in the blend stays in the stomach longer and helps with the hours-long hunger suppression. Not the cleanest label, but a practical option for readers who already trust the brand from protein bars.
When you lose weight on a GLP-1, a meaningful share of it can come from lean muscle, not just fat. Hitting a protein target helps protect that muscle, but a shrunken appetite makes eating enough genuinely hard, which is where a clean, easy-to-tolerate protein powder earns its place as a bridge.
A shake is most useful when appetite is quietest, often at breakfast, or as a stand-in when a meal just isn't happening. Liquid protein tends to go down easier than whole cuts of meat on a slow-emptying stomach. Look for a short ingredient list and a sweetener you tolerate; some people find sucralose-heavy formulas rough on an already-sensitive gut.
