What we solved
No jitters.
No crash.
Caffeine on its own floods your system, spikes your heart rate, and leaves you wired then wrecked. The trembling hands, the racing mind, the 3pm freefall.
We fixed it in the chemistry. CRUX pairs strong coffee with 200mg of L-Theanine, the calming amino acid from green tea. It takes the edge off caffeine without taking away the energy. The spike becomes a steady curve, and the curve holds for hours.
You stay dialed in, calm, sharp, in control, then come down soft.

The calm ingredient
Caffeine brings the energy.
L-Theanine keeps it calm.
L-Theanine is an amino acid found in green tea. On its own, it relaxes you without making you drowsy. Paired with caffeine, it does something better: it smooths the surge, so you get the lift without the shaky hands, the racing heart or the crash.
Every CRUX sachet carries a full 200mg, the dose used in focus research, matched against 180mg of caffeine. That pairing is the whole trick. It's why one cup feels like clean, quiet energy for hours instead of a jolt that quits on you.

Why we made CRUX
Regular coffee is a gamble. Some cups leave you buzzing and anxious. Some barely touch you. And even the good ones drop you at 3pm.
We're athletes and founders. We didn't need more caffeine. We needed caffeine we could trust.
So we spent months getting one recipe right: strong freeze-dried coffee, a full 200mg of L-Theanine, and a pinch of Himalayan pink salt.
No 40-ingredient powders. No sugar. No crash.
Just black coffee that does its job. For hours.

Questions, answered.
What is CRUX?
Strong black instant coffee with 200mg of L-Theanine and a pinch of Himalayan pink salt. Steady, calm energy instead of a spike and a crash.
Why CRUX over regular coffee?
Regular coffee hits hard and drops you hard. CRUX gives you the same lift with none of the jitters, and you land soft instead of crashing at 3pm.
How do I make it?
One sachet into hot water, cold water or milk. Your call. Stir once. No machine, no filter, no mess.
When does my pre-order ship?
Pre-orders ship the moment the launch batch locks, with free delivery pan India. You'll get an email with live tracking the day it leaves the facility.
Do you offer Cash on Delivery?
No. CRUX is prepaid only. Pay securely by UPI, card or netbanking through Razorpay. Prepaid is what keeps the pre-sale price at ₹599 and shipping free.
Can I return it?
CRUX is a consumable, so all sales are final and we don't accept returns. The one exception: if your pre-order ever falls through before shipping, you get an automatic full refund. No questions.
Is it safe for daily use?
Yes. Everything inside is dosed to clinical research, made in a GMP certified facility and FSSAI marked.
