Depends entirely on how much, how often, and the type and intensity of exercise. If you do too much of anything...
Elite athletes do caffeine. Some even had "bad" diets. But if you look at the most successful athletes who are competing solo for endurance, strength or both, those who are consistent and reasonable in their approach tend to fare better over time. Those who over do anything, workouts, diet, supplements, tend to limit themselves.
There is no shortcut for anything in working out. You get back, what you put in. You can't magically grow muscle without convincing the body to do it. The same goes for burning fat. You could get lipo, but that's so 80's!! All these formulas and powders are great to try, but if they speed up the process, there is a cost somewhere. It just may not be apparent at first glance. As for the products that boost you or help you recover, if they increase performance or decrease the need for rest, it'll cost ya! Try to determine what that cost is. You may have to keep notes on your performance over time to see it. If you're lucky and careful, you might benefit for short periods of time if your body doesn't mind the change in diet or routine. What I've found interesting in running is that sometimes feeling a little lethargic after rest can be combatted by running a little faster than normal for a short period of time. It gives me the same benefit of a nutritional booster.
Please be careful doing this. I know a kid who died using powered caffeine. They are trying to outlaw powered caffeine supplements due to the increasing number of deaths from people using too muchPre-workout supplements are a bit overrated. Spending more than $24 on a '30 scoops per container' full of caffeine is absurd.
Here is what you should do for the savings and will give you the same effects as pre-workout supplements....
Go to Wal-Mart and purchase those 'Great Value' caffeine packets. You add them to water and gives flavors of peach, strawberry, grape, pomegranate, ect ect. Gives you the same euphoric approach without the added ingredients. They cost, I think, $2 for a batch of ten packets (probably cheaper). There you go, you have been given significant data to save money, less unknown ingredients, and receive the same effects as pre-workout supplements without the added ingredients.
P.S. I remember telling this to a few of my friends who workout with pre-workout supplements... Their reaction... "You are cheap."
At least I am not ingesting unknown ingredients. (And I save for the extra calories I need for my diet. The extra steak(s) and vegetables are nice to obtain.)

Do yourself a favor and read up on cancer and BCAA's. Specifically leucine. Essentially it's crack for tumors.I got tired of preworkout formulas being so vague about their "proprietary blend" concoctions and never really knowing what I'm putting in my body, so I came up with my own preworkout mix. I ordered most of it online through Amazon and the Vitamin Shoppe.
After doing some research, here's what I came up with:
Arginine AKG (nitric oxide precursor)
Beta Alinine (the stuff that makes your skin feel tingly)
Glutamine
BCAAs (2:1:1 ratio)
caffeine
Postworkout I take a scoop of whey protein, and if I'm doing a heavier series of workouts I'll add another serving of glutamine and BCAAs.
Can you post some links. I have done research on this in the past and didn't find the link your suggesting. The only studies I saw showed that in pancreatic cancer BCAA levels would spike 1-10 years before diagnosis but they didn't contribute the BCAA as a cause just a by product of the failing pancreas. In fact BCAAs are used during cancer treatment to help appetite in cancer patients. I don't feel they would give cancer patients BCAAs if they were making the cancer worse.Do yourself a favor and read up on cancer and BCAA's. Specifically leucine. Essentially it's crack for tumors.
