xiracetam Dosage(for your reference only)
oxiracetam powder is extremely well-tolerated, and no serious side effects have been reported, even when taken at high dosages. Nonetheless, it’s important for users to bear in mind that it’s a very potent supplement that should be used responsibly.
Recommendations for daily dosage vary considerably, ranging from 750 to as much as 2400 mg or more per day, ingested at intervals and taken in two to three doses. Though studies using higher cumulative daily doses have shown no adverse effects, it is always wise to begin with the lowest possible effective dosage and gradually increase as needed.
For most people, a daily dosage of 750 to 1500 mg split into two or three doses would be considered both safe and effective. Oxiracetam is water soluble and mixes readily, so it can be taken in either capsule or powder form as well as taken with or without food.
While some users advocate the initial use of an “attack dose,” a high dosage designed to quickly build to maximal effects when starting to use a racetam-class nootropic, this is an approach that should be considered with caution. While high doses can potentially deliver maximum effects in minimum time, they also significantly increase the possibility of unwanted side effects such as headaches. For a supplement like oxiracetam, which is known for its mild but noticeable stimulant properties, very high initial dosages are even more likely to result in unwanted and unpleasant side effects.
