Watch the injection technique shown in the introductory videos. No aspiration before injection. This confirms what has been published. Injectors were deliberately instructed to avoid the standard technique to aspirate first. Why? To avoid placing the tip of needle next to or into a vein and risk intravascular injection. . Such intravascular injection places the heart and the brain into the direct line of fire of these toxic nano-particles and their contents. Why more young athletic men? Because these people have large deltoid muscles, hence large veins. This is deliberately ordered medical negigence. There is no defense of this malpractice.
