What people say about P21 and focus
“I have been taking 1mg of p21 for about two weeks, and my concentration has improved markedly but my memory has improved even more so.”
“P21 was a strange combination of unpleasant stimulation and lethargy, which had a pretty negative impact on my sleep.”
“I can personally attest to a lessened overall anxiety level due to both P21 and Semax in combination”
“It doesn’t exactly feel like flipping on a switch to consciousness, and it can make me a bit drowsy.”
