Casein

Years ago when I was living in Turkey, I always liked this brand. Even though Optimum was way more expensive than other supplements, I still tried to buy it because it was my favorite. But unfortunately, not all of their products were available in Turkey. Now that I live in the U.S., I'm always an Optimum customer. After using it for so many years, I know they make the best and most effective sports supplements. ā€” From a long-time loyal customer.

Slow Burn, Big Gains šŸ”„

This casein protein is my go-to for overnight recovery. Smooth texture, no chalky drama, and it keeps my muscles fed while I sleep. Whether I'm deep in prep or just keeping it tight, it's the kind of clean, slow-digesting fuel that actually works. Plus, there's no bloating and no weird additives šŸ’ŖšŸ½ just solid results and a shake I actually look forward to.
