Pre-workout supplements and fat loss.

In preparation for the Ten Week Challenge, I'd like to ask a question I have often mulled over and never really found a clear answer for.

After a mental day at work and I go home absolutely shattered, I have often thought about using a pre-workout supplement to give me a pick-me-up or boost prior to training. With so so many different formula's on the market from numerous suppliers, not to mention the often ridiculous price tag, I have never really ventured into this area (except the occasional use of caffeine).

With the advent of the Ten Week Challenge and my goal to bust my ass and get rid of the excess body-fat I have slowly been accumulating, I want to get the most out of every workout possible. I have been looking around at affordable options and have found the "Pulse" formula from MyProtein.co.uk. It contains the following ingredients; Arginine, Creatine-Ethyl-Ester, Beta Alanine, Tyrosine, Guarana, a little dextrose and some things I have never heard of called Glucuronolactone and Chocamine.

Total carbs come to 8.5g a serving, with 0g protein or fat.

Now I know there is some good evidence in the use of arginine, beta alanine and creatine. Guarana is often used as a herbal pick me up in all sorts of things.

Basically, does anyone have any experience with this or a similar product; do they have an effect? Finally, what sort of effect will it have on fat loss (increased, decreased, none whatsoever)?

Thanks guys

Anyone?

Hey guys, thank you for the responses they are really helpful.

Chi- that's exactly the reason I am going to try it, for early morning workouts. Also evenings when I am shattered too.
