Energy. Anytime. Anywhere.

Unlike coffee or energy drinks, CAFFYN gives you precise control over how much caffeine you consume. Each serving comes in pre-measured caffeine packets, so you know exactly what you’re getting—without sugar, flavors, or stimulants you don’t need.

Anytime you want energy without another coffee or energy drink—morning, workouts, workdays, travel, studying, or gaming. It can be added to water, coffee, tea, or smoothies.

Each CAFFYN stick is pre-measured for a precise dose. Your exact amount depends on the option you choose (100mg, 200mg, 300mg, or 400mg per stick).

You can also build your own custom caffeine dose and explore all available options on our caffeine stick packs.

It’s the same caffeine—just different strengths.

100mg is a light boost, 200mg is similar to a strong coffee, 300mg is a higher-energy option, and 400mg is maximum strength. If you’re new to CAFFYN, start lower and adjust as needed. Always beware that can be habit-forming. Monitor intake responsibly

Pop open a stick, pour it into your drink, and stir/shake. It’s designed to mix fast in water, iced coffee, tea, smoothies, and more.

CAFFYN is designed to be flavorless. In plain water, you may notice mild to noticeable bitterness—this is natural, as caffeine itself is bitter. For the smoothest experience, CAFFYN blends best in larger servings or flavored drinks like coffee, tea, or juice.

Most people feel it within 15–30 minutes. Effects vary by person, but caffeine commonly lasts 4–6 hours depending on your metabolism and timing.

Many people do, depending on tolerance and strength. A common guideline for healthy adults is to stay at or below 400mg of caffeine per day.

CAFFYN is often added to drinks that already contain caffeine (coffee, tea, energy drinks, pre-workout), so be mindful of your total daily intake and consider starting with a lower-strength stick.

The American Heart Association notes that up to 400 mg of caffeine per day is generally considered safe for most healthy adults. Individual tolerance varies, and some people should consume less or avoid caffeine altogether. Our 400 mg tube is intended to flavor and fortify a large water bottle that is consumed gradually throughout the day, not as a single rapid serving.

CAFFYN is intended for adults. Avoid use if you’re sensitive to caffeine. If you’re pregnant or nursing, have heart conditions, anxiety, high blood pressure, or take prescription medications, consult a healthcare professional before using.

CAFFYN contains caffeine anhydrous (pure caffeine). No sugar, no sweeteners, and no added fillers.

You can, but be mindful of your total caffeine. Coffee, energy drinks, tea, and many pre-workouts already contain caffeine. If you stack sources, consider starting with a lower-strength stick.

We take quality seriously. CAFFYN is produced with strict quality standards, and we aim to verify purity through third-party testing where available.
