I think you're seeing the beginning of change. If qualitative (labmax) and quantitative (mass spec) testing becomes more and more accessible to individual members, the number of individuals submitting samples will continue to increase. The traditional models of verifying AAS quality relied on trusting those "in the know" to tell you who was legit. Empowering the individual to verify AAS quality control is a shift.
I think you're right and hopefully the trend continues.
With the wide availability of blood testing and the extremely small amount of blood test results I've seen that are not my own, I'm concerned that interest will drop once people begin expecting other to test product for them. I hope I'm wrong in drawing a comparison between blood tests and substance tests.
The very first thing I did when looking up AAS was look for testing. Very rarely have I seen blood tests evaluated objectively and the only place I've seen an explanation of what test values should be at x dosage is in Anabolics by Llewllyn.
