I've only tried it for my last 2 workouts and I honestly can't say that I noticed a huge difference. I'm doing the Bill Star 5x5 routine and I'm usually not "dialed in" until I my last 2 sets of squats. Lucidrol didn't change that. Just didn't seem to be anymore focused or motivated than I usually am. I'm also self admitted stim junky. I rotate between n.o. xplode, jack3d, venom, ragnrok etc. so maybe my brains all burned out from that stuff. But I've been using reset a.d. for the past month and that stuff has made jack3d work w/ 1 scoop again. So maybe I'm not burned out? I don't know.
As for my wife, she said it was great! She's a photographer and spends marathon time on her computer editing and publishing photos. She said she blasted through 5 hours of work the other night w/out ever stopping to check her email or facebook. For her that's unheard of. She usually grabs one of my venom's when she's working late but said she didn't need it this time. Glad it worked for her. But then again, jack3d works great for me but just gives her a brain splitting headache.
So I don't know if it's my stim use or just our different physiology. I'm gonna keep using them til there gone and hope at some point that I get 1/2 the effect my wife gets from them.
