They were full of excipients if I recall correctly.
So many things are these days.
Do you know of any resources for interpreting the results and deciding how to correct imbalances?
Regarding interpretation, I am no expert myself so I've relied on others knowledgeable to help me. I cannot vouch for everything this guy says but his videos on HTMA have been useful for me. If you want a real expert with a focus on mineral balancing, fertility, etc. then Andra is someone who you should consider speaking with. Her Twitter is a good resource for free knowledge. Andra is no stranger to Peat and the Bioenergetic community.
