What it is: A stimulant-free capsule built around a single headline ingredient: DL-185, a patented form of dileucine, which is two leucine molecules bonded together as a dipeptide. Three capsules deliver 2,000 mg.
Why the ingredient stands out: Leucine is the amino acid most associated with signaling muscle protein synthesis, and most people get it from protein powder or food. Dileucine is the dipeptide version of it, and it is the subject of early research comparing it to free-form leucine. Peptide 185 is a way to add that ingredient on top of a normal protein intake without adding calories or another shake.
Who it's for: Lifters who already have their protein dialed and want to try a newer, research-driven ingredient in an easy capsule format. It's a single-ingredient product, so it stacks with anything.
