Slow-release caffeine (400mg CaffXtend™)
Energy
Energy with no downtime or anxiety. I am sensitive to traditional caffeine, but this one works well for me.

Too powerful
I use it to give up caffeine little by little and because energy drinks are very expensive, but this supplement is very long term, I take it once when I get up and that's it, if it is after 12-1pm and I take it, I sleep FATAL, because the caffeine lasts a long time, that is, it fulfills its purpose but they should make more emphasis on how to take it.

I have not noticed any effects
I am a coffee addict, and when I tried this product, it did not serve as a substitute for my caffeine ration either at the beginning of the day or before training.

Energy that lasts all day
I tried the extended release caffeine and I was really surprised. The 400mg dose gives me constant energy without the typical crash afterwards. It is ideal for those days when you need to be focused and active for several hours.

Useful for those days that are going to be long and demanding. I don't use the product very often, but when I have needed it, it has worked well.

For training
Although I prefer natural coffee, it's a good choice for training. I notice some sweating after an hour or so, but it's worth it.

Occasional
It doesn't give you the typical caffeine kick because it's time-release. I find it ideal to take in the morning on long days to get a boost in the evening.

Extra caffeine to face the day
It is very good for an extra contribution at any time of the day, and being in capsules is super convenient to take anytime, anywhere.
