A natural caffeine source for smooth, sustained energy. A leaf native to the Ecuadorian Amazon containing caffeine, L-theanine, and polyphenols in one plant. Indigenous communities have brewed it for centuries. We made it portable.
Queens, 1995. First-generation Ecuadorian-American. Army. Finance. Running with his community every Saturday morning. Brian Mizhquiri built XCV because guayusa comes from where he comes from, the flavors come from the fruits he grew up drinking, and nobody else was going to do it right. The name is Roman numerals. The brand is built from the inside.
