Thanks to Finaflex and Kleen for giving me the opportunity to beta test their new workout pump creation. I have no idea what this product contains. The instructions say to take 4 caps 30 minutes before your workout and 4 caps on non-workout days. I have enough product for 15 days. Tomorrow will be the first run when I hit calves/shoulders. My first assumption with this is that it needs to build up in your system since it is also taken on off days. I hope that I can get a good feel for this by next Tuesday because I will be headed out of town on Wednesday until the following Monday and there will be no chance of it's use or working out during this time. I will pick it back up upon return though. If this interuption will be a problem then let me know if I should postpone the start until I return from the trip. Until further notice, I look forward to hitting the weights tomorrow.
