I tried their a1m and 2.0 (no lot #s and exp dates), and it works as should. Then again, I bought it from a legit retailer, not an auction site like a bunch of you idiots have been doing.
Both kicked in around day 10 for me. Not a full kick in, but noticeable that i'm on something and it's working. More aggression, added strength, huge pumps, more vascular, slight back pumps throughout the day, hot flashes/ head aches, etc.
Also wanted to add, that I have tried their halo product when it was still legal for purchase. It was complete garbage IMO.
