I can't deny any of the rumors of cooking or transhumanism because I don't have any direct knowledge of that. However, organs can and are transplanted into other humans, but availability and finding suitable matches for transplantation are limited, at least in the public operations. People on waiting lists frequently die waiting for a match. For the wealthy and elite, there is a black market for "donated" (stolen) organs that match the DNA/blood type for a specific purpose, and also to sell at high prices. Organ harvesting and trafficking is a big part of the human trafficking and pedophile industry.
