It makes me glad I have both LSZ and AL-LAD in storage. I bought 100 of AL and 50 of LSZ a year ago after trying a smaller quantity. I still have about 80+ al and 45 LSZ in amber vials, with a dessicant and O2 absorbers for overkill, even though I open and re-purge the gas-tight container with Argon every couple of months. And for the record, they have held up well. A couple of weeks ago I popped 300 of AL and got slammed pretty hard. I also did 300, then 450 of the LSZ several months ago, and they were totally active, with no seeming loss of potency. I have had them stored this way from the day I took them out of the vaccumed mylar, and seems to be working out well. And just as an FYI, I have gotten MUCH better results with higher doses of LSZ. 150 was to weak, 300 really nice, and 450 very similar to the mother compound. I also found out that doing LSZ seems WAY better while outside or at a concert venue. The inside just seems "off" for some reason. AL, however, is really my new favorites psych, having been a huge lover and consumer of LSD, which is hard for me to get now. Used to be easy, but I just don't have the hook-ups at my age.
