It is used both as a stimulant-based medication and dietary supplement, primarily for weight loss and energy-boosting.Ĭaffeine: A natural central nervous system stimulant that is commonly found in coffee beans, tea, and other plant-based sources, caffeine is the most widely consumed psychoactive drug throughout the world.

Now, if you want to buy ECA stacks, it’s as easy as clicking a button from an online retailer. Years later, manufacturers found a loophole: while ephedra was made illegal, ephedrine was still able to be used so long as it wasn’t commercially advertised (think: magazine ads, TV commercials, radio spots, etc.).Ĭapitalizing on this loophole, many supplement brands brought back ECA stacks with a vengeance. Supplement companies had to discontinue all of their ephedra-based products. It was after this high-profile death that the FDA made ephedra alkaloids illegal. Many people were getting sick and some died, including a Baltimore Orioles pitcher Steve Bechler. You might be old enough to recall the trouble that ephedra-based supplements got into due to complications related to ephedra alkaloids. The original formula of an ECA stack cycle was made up of ephedra, caffeine, and aspirin. Let’s take a look at the new formula for ECA, what ECA stack results you can expect, and safer alternatives that provide comparable benefits.

ECA in these doses is thus well tolerated in otherwise healthy obese subjects, and supports modest, sustained weight loss even without prescribed caloric restriction, and may be more effective in conjunction with restriction of energy intake.ECA stacks are the original pre-workout and fat burner supplement. In all studies, no significant changes in heart rate, blood pressure, blood glucose, insulin, and cholesterol levels, and no differences in the frequency of side effects were found. The sixth subject lost 66 kg over 13 months by self-imposed caloric restriction. After 5 months on ECA, average weight loss in 5 of these was 5.2 kg compared to 0.03 kg gained during 5 months between studies with no intervention (p = 0.03). 6 subjects continued on ECA for 7 to 26 months. After 8 weeks, mean weight loss with ECA was 3.2 kg vs 1.3 kg for placebo (p = 0.036). 8 of 13 placebo subjects returned 5 months later and received ECA in an unblinded crossover. Overall weight loss over 8 weeks was 2.2kg for ECA vs. ![]() The safety and efficacy of a mixture of ephedrine (75-150mg), caffeine (150mg) and aspirin (330mg), in divided premeal doses, were investigated in 24 obese humans (mean BMI 37.0) in a randomized double blind placebo-controlled trial.
