I haven't noticed much
I bought them on recommendation, but I haven't noticed much taking them. I guess it depends on the person.

Excellent with caffeine
Caffeine is that simple, basic supplement that never fails, but sometimes causes those spikes, which then also cause a crash. This is an excellent modulator, providing energy without those spikes

Correct.
I have a special immunity to caffeine, or at least to its negative effects, but I started taking it since, due to situations, my sleeping hours have been reduced and I needed to know if I can sleep with more quality, and apparently it is working for me, since I feel more repaired since I started taking it.

Operates in cycles
You notice its effects improving cognitive performance but as it is a sustained effect, as soon as you balance you will no longer notice those effects. I would take it in 3-4 day cycles.
