M-STEN is specifically engineered as a mass and strength building agent that helps you bust through your limits and be more than you thought possible.
M-STEN is here to save the day. When dosed properly results have shown to mimic Superdrol products. Superdrol, beside the harshness on the liver is the conversion to estrogen. M-STEN has no conversion to estrogen and provides its users with solid size and mass gains.
