Before you buy
Questions, answered.
How long does Locked In take to kick in?
Most people feel it within 20–40 minutes. Peak effect lands around 60–90 minutes and holds for 3–5 hours depending on caffeine tolerance and whether you've eaten.
Will it make me jittery or crash?
No. The 150 mg of natural caffeine is paired with 200 mg of L-Theanine, which blunts the jitter and the blood-pressure spike. You get calm alertness rather than the lift-and-drop of an energy drink.
What does it taste like?
Crisp and sour, not chalky. Three flavors — Electric Sour Grape, Electric Sour Candy and Electric Sour Gummi Worm. Zero sugar, no artificial colors. If your flavor isn't for you, we'll swap it for the cost of shipping.
Can I take it every day?
Yes — every dose is set at daily-use levels. Because it contains caffeine, treat it like coffee and skip a day or two a week to keep your tolerance from creeping up.
How does Subscribe & Save work?
Choose a 30 or 60 day cadence at checkout and you lock in 25% off every order, forever — not just the first one. Pause, skip or cancel anytime from your account.
What does shipping cost?
Nothing. Shipping is free on every order, every time — one-time purchases and subscriptions alike.
Is it vegan, gluten-free and third-party tested?
Yes to all three. Locked In is vegan and gluten-free, manufactured in the USA in a cGMP certified facility, and every batch is third-party tested for purity and label accuracy.
Are there proprietary blends?
None. Every active ingredient and its exact dose is printed on the label — seven actives, nothing hidden behind a blend name.

I can finally stay locked in for a full work block
I bought LockedIn Brain Fuel because I was struggling to stay focused during long work sessions, especially when I had a lot on. Normally I'd start well, then drift off pretty quickly and find myself getting distracted. Since adding this into my routine, I've found it easier to stay locked in and keep working without feeling scattered. The energy feels clean and steady, not too intense, and I don't get that crash I usually get from other products.

It helps me get into work mode faster
One thing I've noticed with LockedIn Brain Fuel is that it helps me switch on faster when I sit down to work. Before, I'd waste a lot of time easing into things, checking my phone, making another coffee, or putting tasks off. Now I'll mix this up when I know I need to focus, and it feels much easier to get started and stay productive. I also really like that it doesn't make me feel jittery, which has been my issue with a lot of other focus products.

A much better option than another coffee
I was relying pretty heavily on coffee in the afternoons, but it got to the point where it either stopped helping or made me feel a bit on edge. I wanted something that would support focus and energy without feeling too full-on. LockedIn Brain Fuel has been a really solid replacement for that extra coffee. I feel more alert, more clear-headed, and better able to get through a full work block. The flavour is also way better than I expected, which makes it easy to use regularly.
