Positive experiences
“The effects have been incredible. It feels like my background distractibility has just vanished. I can lock in and focus even when my phone and other distractions are right next to me.”
“This shit is the shit!! This is what I wish weed and alcohol felt like! I was chill, listened to music, got work done, didn't want to procrastinate. My ahedonia was gone. I hope this shit isn't dangerous because it is awesome.”
“I like semax and selank especially cause of their antidepressants effects, they work better than any other antidepressant for me. On top they provide some cognitive boost and mild anxyolitic effects.”
“It gave me notable stimulation and a clear headed feeling. There was no withdrawal effects when discontinued.”
“All of a sudden I am feeling like myself again. I am cracking jokes when I'm with others...I feel less like a piece of cardboard and more like a human.”
“I seem to forget less stuff / I am generally in a better mood.”
Negative and mixed experiences
“I think Semax actually made my brainfog much worse, or the combo of that and PE-22-28.”
“Ran a cycle of semax for cognition, no changes noted but I feel this one is a long term process.”
“It gave me a very clean awake feeling and just a slight mood boost.”
“Semax is the only thing that's worked for me for anxiety, low mood, and anhedonia... semax at this dose definitely causes headaches late in the day.”
“brainfog and problem with concentration. At first he even helped me, but after the addition of piracetam, horror began.”
“Semax worked to clear up some of the brain fog for me. Don't need to take it long term, just for a few weeks. Might worsen anxiety while you're on it though.”
