How old are you. What is your current intake ratios (carbs/protein/fat) How much cardio do you do per week and for how long have you been doing it. And what is your body type.
Not all supplements work, period. Some of the ones that do work are not effective for everyone. Not all supplements that work for a person may be conducive of the goals they are trying to achieve.

I guess I don't understand what you want in terms of a kick.

I believe creatine does help in making the Krebs Cycle more efficient and allows you to work a little bit harder than you normally would. Eating the correct types of food in relation to the time of your workout will make you feel more energetic during your routine. And although I don't recommend it, androstenedione will increase your aggression level after taking it for a couple weeks and if you are a person who can use that aggression to further your workout it can be beneficial. But I really really don't recommend it for everyone or anyone who drinks.
