Tekketsu is the practice of blood doping using blood that has been specially treated to make into Laminanium.
Blood doping is an illicit method of improving athletic performance by artificially boosting the blood's ability to bring more oxygen to muscles. In many cases, blood doping increases the amount of hemoglobin in the bloodstream. Hemoglobin is an oxygen-carrying protein in the blood. So increasing hemoglobin allows higher amounts of oxygen to reach and fuel an athlete's muscles. This can improve stamina and performance, particularly in long-distance events, such as running and cycling.
However blood doping using blood that has been specially treated to make into Laminanium causes an enormous jump in one's physical abilities, as the numerous life forces in the blood are channeled directly into their musculature, generating incredibly high levels of raw strength. This means that their muscles are powered directly and continuously by their blended life force, which allows them to generate incredible amounts of physical force in their physical blows and techniques. The consequences of this in battle are tremendous most opponents are severely injured and rendered unconscious upon impact, with only those of a very high enough level being able to recover from it. The physical forces generated by this ability sends many enemies flying through the air for a considerable distance upon crashing into an object or the ground, enough to create large craters upon crashing. Though not usually shown to kill the targets, this ability can readily be brought to lethal levels even to the point of outright disintegrating the opponent on impact. Environmental damage can and will manifest on the ground and nearby obstructions, having walls broken apart, craters forming, and obstacles being thoroughly pulverized. One last consequence of this ability is that at high enough intensities there is a visible discharge of energy, i.e. aura surges.
Tekketsu also induces analgesia during its activation, allowing the user to fight even while bearing heavy injuries. Along with this, it incorporates a feeling of great euphoria, giving the user a great boost in self-confidence and allowing him to forgo certain uncertainties in battle. Because of these effects, Tekketsu has been named the "ultimate battle drug".
In addition to the regular risk of of blood doping, the uprise of ki can easily obliterate user, or severely damage their body.
After running out of pre treated blood ryoma began drawing his own blood treating and storing it for later use.
