That is just it...... there are so many variables that would go into it. AND, not to mention people could say the results were tampered with, even if posted on a piece of paper.
Lots of guys say they have a place they can use for testing until it comes time for it, and they vanish. If the supplier were to send them to be tested, he would be ridiculed for "making a good batch to be tested" if a member sent them in, he would be called a phony if the results came back positive, a "concerned member" if they came back sub par. So basically there is absolutely no winning here now.
Like you said gr8white, many guys are not experienced enough to feel the differences in their bodies throughout a cycle, much less the variations even in one vial. Many people do not understand how receptors play a very important role in this inside of the human body as well, or how it's based on how an individual's body converts testosterone. They base their results souly on crude blood tests of total testosterone numbers. Anyone who uses hormone specialists will tell you this is a very inaccurate way of measuring, but for some reason many still think it's the final verdict, sadly enough.
