I've taken 1-AD and I did like it. The gains I saw from it were not massive by any stretch but they did make the people close me do a double take. You will notice that you are sleepier through-out the day and if you drink water, like you should, you'll be pissing just about every half hour. That part's annoying as hell, but what can ya do. Other than that, I don't really have any definitive proof that would say it's more effective than the rest.
Currently I just started my second cycle of 1-Test by Nutrex. I was hesitant at first about it but in my second week of my second cycle (now) I have noticed an increase of 10 pounds in just about all weights. I am much more fuller, granted I'm no gargantuan but I notice a slight difference. I'm taking pictures week to week so that I can track my progress, no measurement's though I'm too lazy I guess. I haven't really noticed anything unusual while taking it. I do notice that I am more hot and a little more tired than usual but I cannot directly relate that to the 1-Test. My apartment has the heat cranking and I just got over a cold so I may have some residual effects from that.
Those are the only two products I have tried and I must say that I do like the both of them, the latter of the two being my preferred pro-hormone as of now.
Hope some of this helps.
