Did you try using the Recipes tab, rather than Experiment?
Did you re-read Imal's Research, or give the ingredients to another character to try?
If that doesn't help, please email supportdos@larian.com, with a brief description (or link to this topic) and the report.zip file (or a Dropbox or Google drive link, etc) generated by the
D:OS EE Analysis Tool (for Windows).
Extract the zip file somewhere and run the AnalysisTool.exe. When that loads, browse to the install folder (if it is not automatically detected), optionally run the tests first, and then generate a report (it will be saved in the same location as the Analysis Tool).
The report will contain system and game information, as well as your saved games. To reduce the file size, you can delete all but your latest save from the zip.
