Trust or not trust that's not the issue here, we're talking on facts. blood test is a fact that if the member receive the gear freely or not it doesn't matter. even the blood test will be good or bad - he will publish it. so in this case both of the parties will benefit from this. the member will have free products for testing and we'll have the proof of the blood test if the quality is good.
Again I'm not trying to bash your lab I've heard good things. But like ben said it doesn't hold much weight if you know who is sending the gear in. A less than honest lab would send overdosed gear so that person could get it tested. Then they'd have 100s of new customers that'd theyd sell underdosed gear to and when questioned about theyd show where it was tested.
