Fast-acting energy strips.
Strawberry Mint.

No joke — it's a smarter route in. Swallowed caffeine takes 30–45 minutes to peak and drags sugar, acid, and a crash along with it. Slyp dissolves under your tongue and absorbs through the tissue there, so 40mg of clean caffeine gets to work in about 10 minutes.†

That's the point. Because almost none of it is lost to digestion, a sublingual 40mg does the work of a much bigger swallowed dose — enough for a clean lift, not enough to wreck your sleep or your nerves. Need more? Take a second strip.

Place one strip on your tongue whenever you need a lift. It dissolves in seconds — no water — and the caffeine, L-theanine, B6 and B12 absorb sublingually. Most people feel switched on in about 10 minutes.†

The formula is built against that: L-theanine is studied precisely for smoothing caffeine's edge — alert and focused, not wired. Plus the 40mg dose is calibrated for lift without overload.†

Four clean, research-backed ingredients: 40mg caffeine, L-theanine, vitamin B6 and vitamin B12. Vegan, non-GMO, zero sugar, zero calories, no artificial dyes or fillers. That's the whole label.

Slyp is made in the USA in a cGMP facility and every batch is third-party tested. One strip has less caffeine than half a cup of coffee. As with any caffeinated product, keep it away from kids, and check with your doctor if you're pregnant, nursing, or sensitive to caffeine.

Then you don't pay. Every order is backed by a 60-day money-back guarantee — even if the tin's empty.

One strip carries 40mg of caffeine — about half a cup of coffee — but because it absorbs sublingually instead of fighting through digestion, the lift feels quicker and cleaner than the number suggests.†

Yes. Start with one and see how you feel in 10–15 minutes; a second strip still keeps you under one cup of coffee's worth of caffeine. We'd skip strips within 6 hours of bedtime — that's what the Sleep tin is for.

Whenever the fog rolls in: the 2pm slump, before a workout, mid-road-trip, before a long meeting, or landing off a red-eye. It works in about 10 minutes, so take it when you need it — not 45 minutes ahead.†

Three reasons: speed (minutes, not most of an hour), the curve (L-theanine means no jitters and no cliff), and the baggage (zero sugar, zero calories, no acid, nothing to stain your teeth). And if it doesn't beat your current routine, the guarantee makes the experiment free.

Far less than a 200mg cold brew at 3pm. The 40mg dose clears in a few hours — take your last strip 6+ hours before bed and you're in the clear for most people.†

Generally yes — the formula is intentionally simple. If you take prescription medication, are pregnant or nursing, or are sensitive to caffeine, check with your doctor first.

That's half the point. The tin is pocket-sized, the foils are single-serve, and there's no liquid — TSA doesn't blink. Airports, flights, and hotel mornings are where Slyp shines.

Every order carries a 60-day money-back guarantee. If it's not beating your coffee run, we refund you in full — even on an empty tin. No hoops.

Your packs ship automatically on your schedule (every 2, 6, or 12 weeks by tier) at the locked-in discount. Pause, skip, or cancel anytime from your account in two clicks — no phone calls, no retention scripts.

The formula and the restraint. Clean caffeine paired with L-theanine at honest doses, B vitamins for the baseline, zero sugar or dyes, a flavor you'll actually like, and a tin you'll actually carry. No fluff. No fillers.
