anything like Jack3d I can get in single serving bottles??

[QueBert]

I started Couch to 5k recently, did the 1st day of week 3 tonight and it kicked my ass big time, I could only do 2 minutes of the final 3 minute run. I have 3 friends who work out and all 3 of them swear by Jack3d. It gets great reviews on Amazon and GNC.com too. GNC has it but it's in a big tub, the guy that works there recommended it too, and it was one of the cheaper supplements they carry. I'd like to pick up a few single servings of it or something similar to see how it works for me before I drop $30 on a canister. I haven't worked out seriously in over a decade, and I'm not sure if I'll be able to finish the C25K program without doing every week twice from here on out. My goal is to complete the c210k program before the end of the summer. Would this pre workout + Muscle Milk post workout be overkill?
