I was charged $140 for a hair analysis. I am not sure his re-test price thinking 140 but you can ask.
I use to spend about $660-$700 while on Endo Met supplements.( Was on 3 doses aday). Now I pay 100-120 for 3 month supple working with Rick Malter (Most TEI supplement). I am only on most of the supplements now 1 x a day and 2 supplements 2 times aday. He has no issues if you choice to buy your own vitamins or have left overs that he recommends you taking. Like I have my own Magnesium and potassium from my local vitamin store.
I messaged you the rest of the info I know about Rick.
PS. IN the early 70's Paul Eck and Dr David Watts were researching together and Pual Eck at this time started ARL (does not was hair). In the Early 80's Eck and Watts split from an arguement. Watts Opened a lab very similiar to ARl called TEI (does not was hair). ARL lab is located in Arizona and TEI in Texas. On Another group Fernand did a short study on hair analysis and both had verry similiar findings. SO both labs are very close in their testing.
Hope this help you.
