Yuzu Pulse

“Morning light, sharpened.”

First production run · small-batch · full-dose label

Yuzu Pulse borrows the first hour of morning — cold air, clear light, a lemon-lime edge sharpened with yuzu character that wakes the palate without sugar's noise. Underneath, 150mg of natural caffeine paired with 200mg of L-theanine builds a lift that arrives smoothly and holds its line through the deepest block of work.
