New ‘Doping’ Practice Being Abused is Highly Dangerous
One very dangerous practice currently being abused by some individuals, is the administration of carbon monoxide into the body.
This highly deadly gas, occupies the sites on the haemoglobin molecule that normally bind with oxygen and is not readily displaced, forming the compound CarboxyHemoglobin.
Couple of nice studies about the tHb-mass test for those that don't know what I'm on about.
