Certification is fairly simple. Actually doing it is a different matter. For one, you need equipment and the other part is the expense. It will cost you $30 a year to maintain your certification to test. The other part is the expense of the serum. Right now IF you can find the serum it is costing about $212 a bottle. Plus it needs to be shipped over night and kept cold. I do have some extra serum I could sell you if you decide to do your own testing.I'm about halfway between Topeka and Manhattan. I'm not in a big hurry, but I'm waiting to hear back from a guy in Manhattan right now. The testing looks pretty simple, but I'm not clear on whether I need to get certified to do it as part of the whole process. Right now I'm just looking to get answers to make sure I'm doing things properly and can continue to do so moving forward.
