I've tried the Nootropics Source spray, and while I've posted in the past, it was an interesting compound, the bottom line with the spray was I didn't think it was cost effective.
I didn't try subcutaneous injections, and am now thinking maybe I should give it another, final, try.
First of all, thumbs up or thumbs down, now that it's been out a while.
Next, what dose and protocol would you recommend.
Finally, if you have another source of p21 you think is more effective, please feel free to PM me.
Thanks as always.
