I just received on a Tuesday, and have taken only 3 days so far. Noticed more focus from the first day. Will tell more after taking more.

I'm really liking how the energy seems very clean with no jitters, doesn't come on too fast but also doesn't take long

Excellent! Gives me the clean clarity that I need to operate at a high level with no crash hours later

The pills did not have a bad after taste to me, however 5 pills is a lot to take in at one time. Unfortunately I did not feel any different after taking them for 5 days.
