Actually, I did a post a while ago about this product. I'm glad it was free!
It's severely underdosed. If I were you, I'd take double the dosage preworkout only at least. Actually, you're better off buying the ingredients seperately IMO-
Here's the recommended servings for the ingredients-
1-4 grams effective dosage with at least 1 gram preworkout.
The daily dosage for most will probably fall in the 3-12 g range. Exceeding this amount is not recommended, and the dosage should be started on the lower end of this range to determine personal tolerance, especially if one is taking stimulants or antidepressants. The dosage should be divided among 3 or more doses daily. Around 2 g prior to exercise may be used to improve athletic performance.
3 grams pre/post is most effective.
2-3 grams pre/post.
At least 10 grams once postworkout, once before bed.
