I didn't notice a difference. These don't even seem to have caffeine.

Seal was "stuck" to the lid, bottle was easily opened without needing to remove it. Tried a pill, felt no effect at all. This is junk.<br /><br />I'm personally sticking with getting caffeine pills from Walmart going forward.

I was expecting any effects taking this but I hardly notice any changes.<br />Seems my morning coffee works for me.

The shrink wrap around the top cap was loose, and the seal was stuck to the cap, rather than the lid of the product. I won't be consuming this, I'll be throwing it away and going somewhere else.

I like that this product doesn’t cause jitters. You take it and you feel awake. It lasts all day without side effects.

No Expiration Date on the bottle
