What we have so far
Sulfate and hydrochloride are not interchangeable in the trial record, and most of the positive evidence used the sulfate form the negative trials did not.
This star is on the map because the show intends to take the question apart properly — the trials, how it is actually tested, whether the thing sold is the thing studied. That work is not done yet, and nothing here should be read as a conclusion. When the investigation is published it will appear on this page.
