ok i tried this product several times over the last few days. Im taking a summer calculas course, so i need to stay focused? However this product only makes me tired. I tried the recommended serving of 500 milligrams, and 1000 mg and 250 milligrams.On each occiasion it made me extemely tired, even when used with 200 MG of caffeine anhydrous. Most importantly it made it hard to concentrate on anything. I've tried Ergopharm's gabatrophin which seems to work alot better than this. Overall this was the worst product i brought made by bulk nutrition. |
