I tried exactly this one, it only increased day time fatigue so not useful if the aim is to improve negative symptoms. It have its uses too like it reduces joint, ligament pains etc.
For improving mood, energy DMG/TMG best. These are from sacrosine family. But sacrosine is linked to various side effects and DMG is the safest among these and gives similar effects too without over stimulating. Forget about research and try it and feel the difference yourself. Buy from now foods brand, they are selling it. DMG 125 mg. Take it morning without food.
