I went ahead and updated our spreadsheet to show what it would cost you retail if you were to try and make your homebrew Ultima.
You will notice that there are a few compounds highlighted in yellow. These are ones that I cannot find that are sold in bulk or reasonable-priced single ingredient caps, so I tried nest I could to guesstimate a retail price of bulk powder for each one. Trust me, if I took the capped price, it would be even higher. The MB12 has been extrapolated from the AOR caps, as the only bulk MB12 I could find, from Kirkman, worked out to be $500,000 per kilo, serious.
