Androsterone has proven to be a very good buffer to androstenone…which is probably why those little bottles were so effective (despite their relatively simplicity). I’m probably going to give A7 a try eventually..especially since it seems to be growing a preference over NPA on LS.
On another note…
I’ve been playing with NPA again recently and have had great results. I had forgotten how good NPA is as a sexual product…good stuff.
