I started using the AvoGen Labs Anomass-400 two months ago and I can say it's good stuff. The proof is in the pudding: my results have been stellar. Because it's 400mg per ml, it's a little thick, but I had no issues using it with a 28 gauge needle. This was my first naps order and first time with AvoGen labs. I have another AvoGen product on hand to try, and if it's as good as the Anomass-400, I'll definitely be ordering again. I ordered on Sunday and received the items on Thursday. Packaging was discreet. They did ship 8 vials in one package; I might consider making separate, smaller orders to avoid putting too much in one package.
