I'm big into nootropics these days and an interesting drug on many of these sites is Tianeptine. It was found in July of this year that Tianeptine, formally thought of as an anti-depressant, is really a mu and delta opioid receptor agonist. I have a nice little stockpile of it and decided to dose it at 120mg and it indeed works well, it's a decent buzz if not a little too short lasting. So here's a new drug to add to your arsenal, you can get it at nootropicsdepot.
Anyone else try this stuff? It's nice to have a legal alternative to kratom.
