L-Tyrosine
Supports mental drive during pressure blocks by feeding neurotransmitter pathways linked with motivation and cognitive performance.
Description
Be fully there.
Lock In is made for the moments where attention matters: exam blocks, late study rooms, founder sprints, creative sessions, pressure days, and the quiet hour before something has to move.
The goal is not hype. The goal is presence: caffeine-free alertness, clear focus, cognitive readiness, and calm control without the usual stimulant spike.
How it fits
One sachet before the block.
Mix with 350–400ml cold water, shake or stir well, then start the session. The ritual is simple on purpose: one clear signal that the next block matters.
- Caffeine free
- Sugar free
- Gluten free
- Suitable for vegetarians and vegans
Formula
The active stack.
Developed with specialised nutrition chemistry support and organised around three jobs: drive, alertness, and control.
Acetyl-L-Carnitine
Supports cellular energy metabolism, especially useful for longer sessions where stamina matters more than a quick hit.
Citicoline
Supports acetylcholine pathways involved in attention, learning, memory and efficient communication between neurons.
