Fat burners are described as something that will either
burn more FAT, than normal, or inhibit FAT from being created.
Caffeine could be considered a FAT burner, since it raises the
heart rate causing the body to burn more calories, but it's
affects on burning FAT are minimal.
Stacking refers to taking more than one drug at a time to get
more of an effect. Taking caffeine, ephedrine, and aspirin at
the same time will produce a greater effect than the total if

whose address is listed in #34)
From the JUNE/JULY 1993 issue of Muscle Media 2000. According
to a study in in the American Journal of Clinical Nutrition
According to the study, the stack that proved to be the most
effective is 20mg ephedrine / 200mg caffeine. They also suggest
adding 300mg of aspirin to further enhance the thermogenic effect.
The stack should be taken 3 times a day to optimize the "FAT-burning"
effect. The study says the side effects, insomnia, jitterness, etc.
are only temporary.
The study also surmises that the stack may also inhibit the bodys
ability to form FAT as well as burn it.

The "optimal" synergistic effect of caffeine and ephedrine is
reported in numerous muscle mags (for want of more reliable sources)
as 1mg ephedrine to 10 mg caffeine. A dose of 20 mg of ephedrine with
200 mg of caffeine is used in the studies. A product containing these
two compounds in this ratio (but not the only product, just the only
one I know off hand) is TwinLab's RIPPED FUEL. It is also HUGELY
expensive. [RIPPED FUEL's capsules have proportions of ephedrine to
caffeine at 20mg to 100mg. big thanks to George Berger for pointing
this out..] A less expensive route is to buy ephedrine (either in pills
or drops) and use coffee as your caffeine source. The problem with
this is that the amount of caffeine in coffee varies with the type of
coffee how it is brewed. A bench-mark I use is 1 cup of coffee =
If you are really interested in the thermogenic combinations, adding
an aspirin to the mix increases the effect, and naringenin (found in
grapefruit and grapefruit juice) prolongs the caffeine effect.
Theophyllin (sp?) in tea is reported to be thermogenic as well
(according to Michael Colgan), although caffeine levels in tea vary
more than do those in coffee. Chinese green tea supposedly contains
ephedrine and caffeine (according to Robert Haas) although I have
yet to find anything that shows what the levels of each are.
Also from R Scott Smith
Thermogenesis is the conversion of fat and food to produce heat, and
not chemical energy (ATP). When thermogenic effects are stated, it
implies that the substance or substances encourage the body to
increase metabolic rate in the production of heat. This generally
results in an increase in body temperature (of at most 2 degrees,
from what I've read, although I don't recall if those were fahrenheit
degrees or Celsius degrees). This corresponds to an increased
utilization of calories and as a result, fat loss.
