Raw-note based Semax experience for sharper thinking, more energy, and better physical drive. Around 350 to 500 mcg by subcutaneous injection made the brain feel much clearer, increased day-to-day energy, improved movement, and seemed to increase gym strength, while also improving dream intensity and sleep quality. A later afternoon dose helped sleep but left the next day feeling tired and mentally flatter. Headache was experienced when those was 600 micrograms in the morning it was also experienced at 400 micrograms when taken at night My regular dose now is 400 micrograms in the morning
