Triple Strength Myomer
Triple Strength Myomer (aka TSM) is bulkier and also more expensive than standard myomer. It can be used in the "muscles" of BattleMechs instead of standard myomer, and delivers significantly improved performance when the 'Mech has hit a certain heat threshold. Under these conditions the 'Mech will move faster and deal more damage with physical attacks.
This should not be confused with Myomer Accelerator Signal Circuitry (MASC), an entirely different technology that is incompatible with TSM but also improves myomer performance.
The Federated Suns intentionally leaked early research results regarding TSM to the Capellan Confederation during the Fourth Succession War. The Capellans were quick to copy the technology and the 'Mechs of Warrior House Imarra, who guarded the Capellan capital at Sian were equipped with TSM first. Unbeknownst to them was the fact that this early version of the improved myomer reacted violently when exposed to a certain gaseous agent. The Kathil Uhlans took advantage of this to during the extraction raid to Sian for double-agent Justin Xiang Allard at the end of the war, by fogging the entire area with the green gas; this led to violent explosions whenever the armor was breached on a defending Imarra 'Mech, and rendered them incapable to mount an effective defense.
Much to the chagrin of the Federated Suns, the Capellan Confederation was the first to perfect the TSM formula and gained a valuable technology which they later used as a bargaining chip to gain further technologies from the Free Worlds League. This perfected TSM went into use in 3050. 
 Industrial TSM
As part of the experiments that led to Triple Strength Myomer, the NAIS and other research firms went through several prototypes. Though unsuited for combat use, there were several formulations that held promise for Industrial applications. This information, released in 3040  allowed IndustrialMech manufacturers to create Industrial Triple Strength Myomer which was ideally suited for loading, hauling, and other heavy lift tasks.
Triple Strength Myomer is manufactured on the following planets:
|Ares-Bergan TSM||Ares||Bergan Industries|
|Cosby ThermoFlex||Vega||Cosby Myomer Research Firm - (Cosby BattleMech Research Firm)|
The original formulation was actually Quadruple Strength Myomer, it was to bypass the weakness of the gas catalyst that caused Liao researchers to reduce the specifications on it as well as the side effect of it only activating under moderate heat.
