Billyde,
Did you change anything else, other than adding 1-ad to your supps? I mean, did you change anything about your workouts....I'm a psych major, so I'm a firm believer (and therefore skeptical) in placebo effects. That's a pretty big gain in weight to be attributed to a placebo, but for arguments sake, if you started working harder after starting your 1-ad cycle, it could be that those changes in workout intensity are playing a big part in your changes. Not saying this is the case, just playing devil's advocate here.
What needs to happen, and I believe this is true with any supplementation/training change is that people need to document things. Document when you start cycling supps, document your workouts and if you are really good, document your diet (i'm bad about that). That's really the only way you are going to prove to yourself that whatever change you made was responsible for changes in your body.
If and when I do start my 1-ad cycle, I"m going to try and hold everything else constant (supps, diet, workout system) and see if the addition of 1-ad correlates with significant changes in my body.
Just some thoughts on the subject....of course, as with anything in the world, you have to allow for individual differences. Likely, younger guys (sub 25) are not going to experience anything from this stuff, because their bodies are already raging with test. But for older guys like billyde and I, if this stuff really does jacked up our tapered off test production without aromatizing, then maybe it's worth while to look into.
