What got worse for some people
In their own words
“However, I noticed if I take too much I feel depressed af, and the dreams are next level!”
“Today is day 3 of 300mg. Blown away... Libido, motivation, energy, drive, focus, ability to enjoy things, being excited again, all of it just popped back into my life.”
“Not long after that I was absolutely flying - increased sociability, positive thoughts and just motivation to get shit done.”
“I started taking 300mg alpha GPC 2-3 times a day and my anxiety is GONE.”
“I started taking alpha GPC + Piracetam a few days ago and I've noticed significant improvements in my cognition.”
“the static had completely thinned out and disappeared... its not as effective as it was originally. its starting to bleed through and gets slightly worse (rebound?) when its out of my system.”
