Wow, very thorough feedback! I'm glad its treating you right!I've gotten my tolerance up to about a scoop per day, divided into 2 doses. Really great energy..and I am VERY picky about and sensitive to stimulants. Very nice pick me up in the afternoon when I sometimes start to fade, but even more important it still lets me sleep, not have a crash and stay in a pretty upbeat mood. This is a winner for me as I am a wildlife biologist that needs to be alert, energized, in a good mood (I deal with construction workers all day) but not cracked out.Most stims end up wearing me out after a few days either because of the excess adrenal stimulation or because my sleep pattern gets disrupted. With the adjustable dosing that Alphamine allows for, I am finally able to fine tune the stim to my desired level. The ingredient profile is great and I've never responded to any form of Yohimbe/Yohimbine as well as with Alphamine. I feel warmer, more vascular, with a big increase in libido. Mood and mental state are positive with no big crash though I do feel a little flat after it wears off completely...NOTHING like an EC crash though. No prostate issues.
