In some of the test groups I am in and have run for peps, the donators (financial and product) will usually be the first to obtain the tests then within a period of time let's say 10-14 days, they would be put up on the server. If there was any type of mass/purity/sterility issue it would be made public right away to warn the community. Since it's a community, it like buying a round of drinks at the bar. You get a round, your buddy gets a round, the next guy gets it, etc... In the end, for the most part it should even out with paying for tests and sharing them out in my opinion. I like to test anything and everything before I put into my body, so I am usually a contributor of product or financial, and/or even coordinating.
