Can someone suggest best 'Instant' coffee for increasing concentration at work? (Delivers online within UAE)

I normally prefer freshly grounded roasted coffee beans using pour-over method of making coffee. (Columbian coffee)

But the whole process takes at-least 15 mins, which is too much time before leaving for work.

Other problem with my current coffee is, it makes me active for all unnecessary stuff like doomscrolling, watching cat videos etc. therefore, I'm looking for other good suggestions for instant coffee, which also increases your concentration at work.

Thank you.
