GAT SPORTEssentials Caffeine (200mg)- 100 Tablets

It is very effective, it gives me energy and keeps me from sleeping.

good and genuine product and effective but disrupt sleep!

The pills are very strong so if you're new, you might want to start with taking half a pill.They kept me much more alert than regular coffee or espresso ever do, and their effect lasts a good while.I don't regularly take them, but if I ever find myself low on energy and have something important on hand, like an exam, they basically freshen me up similar to taking a good nap.However, they can cause your mouth to feel very dry for a good while if you're not used to taking them, so I would recommend starting with half a pill or less at first.

I donot have

Its a standard caffiene supplement, clean and pure.A pill with a glass of water usually does the job for me and keeps me alert for a good hour or two but it's always better to make proper sleep your first priority and use this supplement as a backup only ocassionally.

very good

Good Quality with right price

Useless, I have been taking it for days and it doesnt do anything. Better stick to regular coffee.
