Questions & Answers

Common questions about our protein shots.

Regular protein shakes are made for bodybuilders with big appetites. Leuciva is made for GLP-1 users with low appetite.

21g of protein in just 3oz — easy to finish when you can't eat. More Leucine than typical shakes because of how it's filtered, helping preserve muscle while you lose weight. And it's formulated for GLP-1 taste buds — clear, light, and refreshing. Not thick, syrupy, or overly sweet.

Small volume. Big protein. Taste you'll actually enjoy.



Yes. Our precision-fermented whey is lactose-free and easy to digest — no bloating, no discomfort.

We use BLG (Beta-Lactoglobulin) — more concentrated, more Leucine, less liquid. That's how we fit 21g into 3oz. No thickness. No bulk.


Taste like a delicious and refreshing Blueberry Lemonade. Clear and light like juice — not thick, syrupy, or overly sweet. Bold, refreshing flavor made for GLP-1 taste buds.



We made it for GLP-1, but anyone who wants easy, high-protein can use it.


Nope. That's exactly why we made it. Big 12oz shakes and heavy protein meals are hard to stomach on GLP-1. Leuciva is just 3oz, small enough to finish before your appetite says no.
