What is Project MKULTRA

MKULTRA was a series secret government experiment that went on from 1953-1973, for those of you not good at math that is a full 20 years. The ultimate goal was to produce the perfect truth serum. There were many techniques used. Anywhere from drugging people with large amounts of pure LSD to hypnotism to electroshock therapy. These experiments were not only conducted here in the US at hospitals, prisons, and universities but also at McGill University in Canada. Those sent to the McGill University came in with minor issues such as minor depression and anxiety and if they left alive they were not the same person. Thier personalities were completely altered and many came out unable to speak. Now, this is where the questions start coming in, what were they doing in there? Did they intentionally alter the speaking capability of these patients? What else happened that was lost in the documents burned? And most importantly, is it still going on?

Also, is the infamous Polybius another undocumented experiment withing MKULTRA? Now for those of you who have no idea as to what I am talking about it will be referenced later when I point you to a youtube who has some excellent points but I will surely add on to what he is missing.
There is still so much information missing in the files that were declassified from MKULTRA, so what is the government hiding? I'm going to do my best to interperate what I find and see if we can get any closer to the truth behind this conspiracy.
