  • "Amped Orange actually tastes good, which was my biggest worry with liquid supplements. Mixes easily into water and doesn't leave that chalky aftertaste. Been taking it before workouts for a few weeks now."

    David
  • "I like that it's liquid instead of another pill to swallow. Easy to measure out and travel with. Noticed I have more energy during my afternoon gym sessions since starting it."

    Rachel
  • "Ordered this after my trainer recommended L-carnitine. The orange flavor is solid and it's become part of my daily routine now. Packaging feels premium for the price."

    What's Inside

    Five actives, fully dosed and fully disclosed. No proprietary blend hiding an under-dose behind a label. Every flavor carries the identical formula, so picking one is purely down to taste.

    L-Carnitine
    4,000 mg per serving
    The core active. Carnitine's role in the body is transporting fatty acids into the mitochondria, where they are used for energy. Liquid form, so there is no capsule to break down first.
    Super Carnitine (GBEEC)
    25 mg per serving
    A precursor compound, included to support your body's own carnitine production alongside what you are taking directly.
    BAIBA
    300 mg per serving
    Beta-aminoisobutyric acid, a compound your body releases naturally during exercise. Included here to support metabolic activity.
    Grains Of Paradise
    20 mg per serving
    A West African spice extract studied for its role in thermogenesis. Stimulant-free, so it adds nothing to your heart rate.
    L-Theanine
    200 mg per serving
    An amino acid found in tea leaves. Supports calm, steady focus, which is why this formula does not come with a crash.

    Storage: Keep sealed in a cool, dry place. Refrigerate after opening and use within 90 days.

    Most carnitine on the shelf is a 500 mg capsule with a label that tells you almost nothing. Here is what you get instead.

    • Supports Fat Metabolism A full 4,000 mg of carnitine per serving, the dose the research is actually built around.
    • Energy Without The Crash Zero stimulants. No caffeine, no jitters, no 3pm drop. It stacks with your coffee or pre-workout instead of fighting it.
    • Calm, Steady Focus 200 mg of L-Theanine, so you stay sharp through a session rather than wired then flat.
    • Easier Than Pills One tablespoon into water. No handful of capsules, nothing to break down first.
    • Five Actives, Not One Carnitine alone is the bare minimum. GBEEC, BAIBA, Grains of Paradise, and L-Theanine each earn their place.
    • Fully Disclosed Label Every dose is printed. No proprietary blends, no hiding a sprinkle behind a trademark.
    • Four Flavors, No Chalk Liquid supplements have a reputation. Every one of the four mixes clean with no chalky aftertaste.
    • No Sugar, No Fillers Nothing in the bottle that is not doing a job.
    • Processing Time: Orders are processed within 1 to 2 business days.
    • Standard Shipping: 7 to 12 business days after dispatch.
    • Tracking: A tracking number will be emailed to you once your order ships.
    • Returns: 30-day money-back guarantee. If it doesn't hold up, we'll replace it or refund you.
    • Customer Support: Email us at support@happsta.com, we respond within 24 hours.

    Switching your cells from sugar-burning to fat-burning with HAPPSTA Liquid L-Carnitine triggers a visible change in energy, focus, and body composition

    Kevin W. Kevin W. (42 years old)

    Took my first dose of HAPPSTA in the morning and felt the difference the same day. Steady energy right through the afternoon, no crash, no jitters. It's like my body finally switched on.

    What Sets Us Apart

    Most liquid supplements are built to a price, not to a standard. Watered-down doses, sugar to mask the taste, and a formula you can't actually pronounce. This one is built around the parts that actually matter.

    Frequently Asked Questions

    • Shake well, then mix one tablespoon (15 ml) into water or juice. Most people take it 20 to 30 minutes before training, or first thing in the morning. One serving daily is all you need, so a 16 fl oz bottle runs 31 servings.
    • 4,000 mg per serving, inside a triple-blend liquid formula with four more actives alongside it: Super Carnitine (GBEEC) 25 mg, BAIBA 300 mg, Grains of Paradise 20 mg and L-Theanine 200 mg. Every dose is printed on the label. No proprietary blend, no sugar, no fillers padding it out.
    • Four, and the formula is identical in all of them, so pick purely on taste. Amped Orange Sour Watermelon Sour Gummy Worm Sour Peach Ring Amped Orange is bright citrus and the safest first pick. Sour Watermelon is the lightest. Sour Gummy Worm is the sweetest. Sour Peach Ring sits in between. All four mix clean with no chalky aftertaste.
    • Yes. On any multi-bottle bundle you choose a flavor for each bottle separately, including the free ones. Take all four if you want to find your favorite, or load up on one.
    • One bottle is 31 servings, just over a month. Carnitine works on consistency rather than a single dose, so most people go with a multi-bottle bundle to cover a full run without reordering. The bundles also carry the lowest per-bottle price, and the 30-day guarantee applies to the whole order, not just the first bottle.
    • Every bottle is backed by a 30-day money-back guarantee. If it's not right for you, contact support within 30 days of delivery and we'll make it right. That covers every flavor, so trying one is no risk.
    • Yes. It's built to sit alongside your existing stack, not replace it. Protein, creatine, pre-workout, multivitamin, all fine. Because there are no stimulants in it, it won't stack caffeine on top of your pre-workout or coffee.
    • Yes, keep it daily. Carnitine levels build with consistent intake rather than spiking from one serving, so skipping rest days works against you. On a non-training day, take it in the morning with your first meal.
    • No. The formula is not gender-specific and there are no hormonal ingredients in it. The serving size is the same for everyone. If you're pregnant, nursing, or on medication, check with your doctor first.
    • It's formulated for daily use at the recommended serving size. As with any supplement, check with your doctor first if you're pregnant, nursing, taking medication, or managing a health condition.
    • No. It's completely stimulant-free, no caffeine in any of the four flavors. That means it stacks with your coffee or pre-workout instead of fighting it, and you can take it late in the day without it touching your sleep.
    • No added sugar and no filler ingredients in any flavor. Check the label for the full ingredient list and allergen information.
    • Sealed bottles keep in a cool, dry place out of direct sunlight. Once you open one, refrigerate it and use within 90 days. Reseal the cap tightly after every use.
    • Results vary by individual and depend on diet, training, and consistency. We recommend taking it daily as part of your routine and giving it time to become a habit.
    • HAPPSTA L-Carnitine is sold only through this official store. We don't authorise third-party listings on Amazon, eBay, or other marketplaces, so anything you find elsewhere we can't verify as genuine.
