Trust but verify comes to mind here. I have personally tried to verify this because I work on a project to bring all stories(good, bad, neutral) on novel therapeutics + Long COVID and I have yet to be successful in verifying this with the poster over a couple months.
They told me previously to reach out to a specific Long COVID advocacy group and when I did, that group replied with very limited data as no one had really tried it. Now they are claiming it is a Facebook group with this new post, so something is not adding up here. Let alone all the other public anecdotal and research evidence suggesting the opposite or being neutral. I will continue to try to verify, but I hope you can see why we cannot just trust what is said on the internet as truth.
