ENTER is a functional beverage brand making 60ml performance shots packed with clinical-dose nootropics and adaptogens. Every ingredient, every dose, fully transparent — backed by science, made in small batches in Vilnius, Lithuania.

Most energy drinks rely on caffeine and sugar to create a spike — followed by a crash. ENTER uses clinical doses of ingredients studied for cognitive performance — Lion's Mane, Rhodiola, Citicoline, and L-Theanine — at amounts shown to be effective in research. No sugar. No fillers. No proprietary blends.

Matcha Lemon Ginger — our caffeinated shot with 80mg natural caffeine balanced with 200mg L-Theanine. Blackcurrant Ginger — our caffeine-free shot powered by Citicoline and higher doses of Lion's Mane and Rhodiola. Both are 60ml.

Shake, open, drink. The full 60ml in one shot. No mixing required. Onset is typically 15–30 minutes. Effects last 4–6 hours of sustained focus and clarity without the crash.
