This thread discusses the Content article: SuperPump 250 (Gaspari Nutrition)

I'm not reviewing or rating this product for now, because I don't have any experience with it other than using a sampler.

I did my workout about 45 min - 1 hour after drinking the sample packet. I wasn't feeling any more energetic than a jolt of caffeine would have given me. My workout wasn't any stronger than normal. I was more alert and focused, however, it didn't feel more effective than a CNS stimulant.
