Ephedrine pills

I use the ephedrine/caffeine/aspirin stack for fat loss a couple times a year, and it's definitely very effective.  Its the only thing I've used that was effective enough that I was sure the results weren't the placebo effect.

There are serious side effects for some people (similar to other strong stimulants), so it's definitely not for anyone under 18 or with any kind of health issues.  Definitely start with a half dose to determine tolerance.

I get    90 200mg caffeine pills @Walmart for $3.00
           60 81mg aspirin @Walmart for $2.00
           60 12.5 mg generic Primatene tablets    
                      @Walgreens for $9.00

It's Outside the US you may be able to find pure ephedrine instead of primatene,which also contains guaifesin.

To start, I take half a caffeine pill(100mg), one ephedrine pill (12.5mg), and one aspirin(81mg).
Tolerance build super fast, so after 3 or 4 days I'll double the caffeine and ephedrine (that's the full dose), and work up from one to three doses a day spaced about 4hrs apart.

Tolerance quickly turns to dependence, so I usually limit a cycle to around two weeks, although sometimes I'll increase to a full double dose for a third week before a 2-3 week break.  The withdrawal symptoms can be mildly unpleasant, especially with a high dose for a long period.

Ephedrine is certainly not as "safe" as a multivitamin, and I'm sure some people here will try to convince you it's the same as smoking crack, and for legitimate reasons.  You should do a lot more research and really consider if ephedrine's benefits are worth the risks for the amount fat you want to lose.

The EC stack (or with aspirin ECA) is a stimulant, which has been shown to increase SNS metabolic output more than just caffeine alone. Initially you can get the jitters just like from drinking coffee or soda, but as any regular drinker will tell you the jitters go away after a week or two. The SNS boost however remains, and research has shown the fat burning also remains long term. It also reduces appetite the same way any stimulant would so it can help during a deficit diet.

That said, you should weigh that with the down side, which is increased heart rate and blood pressure. Combined with strenuous activity, your BP could get rather high. And since a lot of people are idiots, they would take way more than the normal dose and pushed their BP even higher, and ended up in serious condition when things eventually popped. Note: heart attack and stroke are not acceptable side effects for a weight loss pill.

So if you have heart conditions or have a hard time with taking a normal dose, then this isn't for you. If that's not a problem, then I would also say that it can help but ultimately it's your diet that matters. I ate 6 big cookies tonight due to lack of control and poor diet planning this week, and the EC stack wouldn't have helped one bit. So get that in line first, and you might find the pills aren't even needed.

Well, one side effect is JAIL as ephedrine is illegal in the USA.  The FDA published a final rule on April 12, 2004, that bans the sale of dietary supplements containing ephedrine alkaloids.
