Folks, if you've recently upgraded or renewed your annual club membership but it's still not active, please reach out to the BOD or a moderator. The PayPal system has a slight bug which it doesn't allow it to activate the account on it's own.
Oceamo-MS is my favorite. ATI-MS is excellent as well. Which ever test you choose, get MS resolution. Lower resolution OES tests will give NA results on many of potentially toxic metals like tin and copper etc..
