- Cortexin+Medivitan
Cortexin is polypeptides of the cerebral cortex of cattle and Medivitan is a mixture of pyridoxine (b6), cyanocobalamin (b12) and folic acid (b9). Make an injection in each thigh once a week or on a stressful day; - MitoQ
Antioxidant. Take once a week for a stable source of energy; - Modafinil
Everyone knows this. Gives you a pump to workout an advanced math book in a day. Once a week is enough; - Anvifen
Facilitates GABA-mediated transmissions. Makes you cool and focused; - Alpha GPC+Selank.
