Gave the X2 a shot after the original worked okay, and this version actually feels stronger. Noticed a real difference within the first couple weeks, and the energy side of it is a nice bonus I wasn't counting on.

Wasn't expecting much after the original, but this second-gen version hit different — noticed the difference within the first week or two. Taking it daily has become part of my morning routine now.

The second-generation formula is noticeably stronger than what I was taking before, and I like that it builds on the original instead of being a total overhaul. About three weeks in and the difference in energy is real.
