This is our bad. When we had shared at Google, we thought the cost would be $2 million. We didn't include the money we had put in or received, so we shared our goal as $1.5million.

Before sharing more publicly, we decided to update to the actual amount and had also learned that some costs would be higher than expected (toxicology package would be higher, clinical care wasn't going to be covered by insurance etc.). We had put a little note describing this in the FAQ, but I understand that no one reads those.

For what it's worth, our goal from the very start was to openly share the process and logistics because we are truly convinced that this N-of-1 process can be repeated quite easily. Perhaps, at the very least we can squeeze the time for the next motivated parent to learn all this from 6 months to 1 months.
