The Consistency Drink for Winners.

Lock In™ is a functional focus drink mix designed as a pre-deep-work ritual. Each sachet contains 150mg Caffeine, 200mg L-Theanine, 500mg L-Tyrosine, Rhodiola Rosea, Green Tea Extract, and our ScreenShield™ berry complex. It helps you enter focus faster, sustain it for 2–4 hours, and avoid the crash that comes with coffee or energy drinks. Mix one sachet with 300ml cold water and you're locked in.

Most people feel the onset within 15–25 minutes. The caffeine + L-Theanine combination kicks in first with calm alertness, followed by the deeper cognitive support from L-Tyrosine and Rhodiola. Peak performance window is typically 2–4 hours. There's no hard crash afterwards — just a smooth return to baseline.

Yes. Every ingredient is dosed within clinically studied safe daily limits. There are no proprietary blends — every milligram is listed on the label. The caffeine content (150mg) is roughly equivalent to a strong cup of coffee. L-Theanine, L-Tyrosine, and Rhodiola are all well-researched with strong safety profiles for daily use. That said, we recommend cycling off one day per week if you're caffeine-sensitive.

Coffee gives you raw caffeine — a spike followed by a crash, often with jitters and anxiety. Energy drinks add sugar and taurine on top. Lock In™ pairs caffeine with L-Theanine (which eliminates jitters and smooths the energy curve), L-Tyrosine (which sustains dopamine for motivation), and Rhodiola (which reduces mental fatigue). The result is controlled, sustained focus — not chaotic stimulation.

Mixed Berry Citrus. The top note is berry sweetness, the mid-palate has a slight tartness, and the finish is citrus-fresh with zero bitterness. We spent months engineering the flavor system — using natural berry and lemon/lime flavors with a precise stevia + sucralose blend that avoids the chalky, medicinal taste most supplements have. It's genuinely something you look forward to drinking.

Right before you need to perform. Most users take it 15 minutes before starting a deep work session, study block, coding sprint, or creative session. Morning or early afternoon works best. We don't recommend taking it after 4pm if you're sensitive to caffeine, as it may affect sleep.

ScreenShield™ is our proprietary 500mg blend of Bilberry Extract and Blackcurrant Extract. Both are rich in anthocyanins — powerful antioxidants researched for reducing eye strain, supporting visual processing, and protecting against oxidative stress from prolonged screen exposure. If you spend 6+ hours on screens daily, this is built for you.

Each box contains 20 sachets — roughly a month's supply if you use it on workdays. Premium matte-finish carton, individually sealed sachets with a 3-layer moisture barrier for freshness.
