effective, convenient
Verified purchase
Its effective, convenient. good for busy mornings or before workouts for a bit of extra boost. It’s not a sleep-friendly option if taken late, so I reserve it for daytime use. A dependable, straightforward supply for mornings and study sessions.

ok so, so I use caffeine to manage narcolepsy... and supplements that are pure caffeine don't cut it. The green tea extract is a key addition to this product that I think makes it so effective, and you can get too much green tea extract if you're getting it in other supplements so be careful

I take this with a painkiller as I heard that it can help with pain relief. Also use this when I need to stay awake to meet deadlines and need the extra energy

These caffeine tablets are the best I’ve found. The quality is great for the price and they work well without giving me the jitters. I take one as part of my morning routine every day.
