I've seen it done with all products. Start taking it then ask questions. I also remember seeing people title threads "AD-1 Question" or something along those lines. How do you not even know the name of the product yet you are taking it.
At this point in my life it bugs the sh!t out of me, but I know 10 years ago I was the same way. 18 years old and willing to take whatever the big guy at the gym or supp store told me too. Didn't take me long to find the net and start learning though
i don't necessarily think it is a case of being standoffish per say, but rather asking a question that has been asked/answered many times prior. lots of people ask questions without searching on the board first, or without reading the stickies.
I only wish I had all this info at my disposal when I was 18-20. I didn't get internet access until I was almost done with college. In my early 20s I went by what the big guys told me, word of mouth, & of course the original Anabolic Reference Guide.
