Founder's note

Why I made this

I built Locked In because I was tired of the trade-off: coffee got me going but left me wired and scattered by mid afternoon, and energy drinks were worse. I wanted something that put me into a focused state and kept me there calm, not jittery for a full work session.

So I put together a stack of ingredients with actual evidence behind them, at doses that do something, with nothing hidden in a "proprietary blend." One tub at a time, refill when you actually need it.

I take Locked In before my hardest sessions. I hope it helps you lock into yours.

Questions, answered.

How long does the focus last?

Most people get 4–6 hours of sustained focus from a single serving without the crash you'd get from energy drinks.

How much caffeine is in it?

Each serving contains 200 mg of natural caffeine from green tea paired with 100 mg of L-Theanine to smooth out the curve.

Will Locked In make me feel anxious or jittery?

Locked In is purposefully formulated to support smooth, sustained focus rather than the intense stimulation often associated with many energy drinks and high-stimulant pre workouts. Every person responds differently to caffeine, particularly depending on their individual tolerance and sensitivity. If you're new to caffeine or are particularly sensitive, we recommend starting with half a serving to assess your tolerance. Our goal is to help you stay focused and productive not overstimulated.

What if I don't like the flavor?

That's covered by The Flavor Swap Promise. If you don't love the flavor of your first tub, we'll send you a different one — you just cover $6.95 shipping. One swap per customer on your first order, claimed within 30 days of delivery, and there's nothing to send back: keep the original tub or pass it to a friend. Just email contact@lkdsupps.com with your order number and the flavor you'd like instead.

When should I take it?

Right before a deep-work block. Avoid taking it within 6 hours of sleep.

Where is it made?

Manufactured in the USA in an FDA-registered facility.

Can I take it every day?

Yes. The formula is built for regular use before deep-work blocks. As with any supplement, check with your doctor if you're pregnant, nursing, or on medication.

Can I have it with coffee?

You can, but you may not need to there's natural caffeine in the formula already. If you're caffeine-sensitive, start with Locked In on its own and see how you feel.

How is quality controlled?

Every batch is manufactured in an FDA-registered facility in the USA, following cGMP guidelines.

What's in each serving?

Each serving is 2 scoops (7.5 g). Full supplement facts including 300 mg Alpha-GPC, 200 mg natural caffeine, 100 mg L-Theanine, and every other ingredient are listed in the panel above. No proprietary blends.
