No, you need a test to tell you what you are sick from. Lot of symptoms are non-specific and the treatment is diff depending on the diagnosis. For example, if you have the flu, your not going to be getting remdesivire or MCAntibodies.
True, different treatments for different ailments. But supplements to help build-up your immune system are beneficial for flu or the variants. As for Remdesivir, I would stay away from that. There are many reports of organ failure resulting from Remdesivir treatments. The MCAntibodies are better, but I'd rather try other proven treatments for flu/etc before signing up for the MCA.
What is very disturbing is the instant and vicious attacks on anyone that dare question the CDC, FDA, WHO, and the medical community on their recommendations. They actions are bully tactics and at least to me, indicate their position is very week, incomplete and they are fearful of loosing any argument on facts.
