taking stimulants before workouts/cardio

[sexy_animal]

I got into the habit of taking a mild dose of stimulants (green tea extract, guarana extract, yohombine, etc) about 30 minutes before working out.

I believe my workout density improved as a result.

Are there any drawbacks to taking stimulants before working out on a regular basis?

I read somewhere that continued use of stimulants burns out your endocrine system, or something along those lines.

Is that true?

I don't really think so - not unless you've already got significant problems.

Preworkout stims are wonderful for releasing free fatty acids - the catecholamines enhance lipolysis in mammals.

What Built said.

You'll only get adrenal burnout if you are using pretty significant amounts of stimulants for a prolonged period of time.

A nice cup of coffee or an equivalent isn't going to hurt you. Hell, I love a pre-WO cup of coffee about an hour before.

Is there any legitimate research on this?

yeah, eventually you will be tolerant to stims, and will need a break. a cycling approach is best, maybe for every 4 weeks on, take 2 off. this may avoid "burnout" and will slow your body building a tolerance.

Or just do what I do: increase the dose.

HI!

HI!

Yup. When the normal stack stops working, try throwing meth into the mix. I hear it works well.
