The issue of Clenbuterol vs. Ephedrine sometimes results in questions and even confusion.
What’s the difference between them, are there similarities, how do the benefits and risks regarding the two compare.
Others want to know whether they should use the Clen ECA stack.
While the similarities often result in sources referring to Clen and Ephedrine as “cousins,” there are also differences.

Are you thinking of taking the Clenbuterol ECA stack? Know the difference between the two first.
Clenbuterol is a beta-2 receptor agonist belonging to compounds known as sympathomimetics.
Although Ephedrine belongs to the same classification, the two are not the same.
Often referred to as “Cousins,” the two have different properties.
Clenbuterol stimulates the beta-2 receptors, accounting for the common referral of Clen as a beta-2 receptor agonist.
Ephedrine, on the other hand, stimulates multiple beta and alpha receptors by an equal but lesser degree.
Clenbuterol is considered more potent, with longer-lasting thermogenic properties.
Ephedrine acts as a central nervous system (CNS) stimulant, a similarity with its cousin. Another similarity is that both are used for temporary relief from some asthma symptoms.
“Does Clenbuterol contain Ephedrine?” is a question some people ask. One does not contain the other. Users can use Ephedrine during off-weeks of the Clen cycle.
Clenbuterol is a popular substance used by bodybuilders and athletes as well as individuals simply wanting to lose weight.
Some individuals use it due to thermogenic and anti-catabolic effects.
As it raises the body temperature, it increases calorie expenditure, initiates lipolysis, the breakdown of fat into free fatty acids, reportedly replacing fat with lean muscle.
Some sources report that it helps burn fat even when the user is not exercising.
It is important to note that after some weeks, those who exercised experienced more significant body fat reduction.
Clenbuterol has quite a Hollywood following beyond athletes and bodybuilders. Several sources indicate that celebrities such as Lindsay Lohan, Britney Spears and Victoria Beckham took it for weight loss benefits.
Additionally, some athletes take Clen to reap the performance enhancing benefits, although the International Olympic Committee (ICC) and professional sports organizations ban it.
Swimmer Jessica Hardy and U.S. sprinter Katrin Krabbe are two examples of athletes testing positive for Clen.
Ephedrine increases heat expenditure, inducing fat loss and mildly increases performance. Unlike Clen, it is touted for weight loss capabilities and fat loss even when not exercising.
Although when ephedrine is combined with diet and exercise it clearly produces better results and may even have fewer side effects.
Some benefits of Ephedrine includes that over time, it decreases skeletal muscle breakdown, reduces triglycerides and decreases appetite in users. It also reportedly produces an increased overall sense of wellbeing.
The increase in metabolic rate, thermogenesis and oxygen rate increase with simultaneous use of caffeine led to the popular ECA stack of ephedrine, caffeine and aspirin.
There are studies and reviews of studies on Ephedrine use, including work prepared by the Southern California Evidence-based Practice Center-RAND. Among the findings:
Ephedrine was associated with statistically significant weight loss of 1.3 pounds/month more than was associated with placebo for up to 4 months use.
Ephedrine plus caffeine was associated with a statistically significant weight loss of 2.2 pounds/month more than was associated with placebo for up to 4 months use
No serious adverse events (death, myocardial infarction, cerebrovascular/stroke events, seizure or serious psychiatric events) were reported in the clinical trials.
There are side effects common to both substances and side effects unique to each one.
Both Clen and Ephedrine result in potential increase in hypertension, palpitations, abnormal sweating and nausea, along with possible cardiac issues.
Clen users more often report muscle cramps while kidney stones are more likely to be reported by Ephedrine users.
To obtain maximum benefits and reduce risk of side effects, clen is not used for long periods without a break, or off-weeks.
Although some sources suggest only one week off, the Clen cycle typically consists of two weeks on and two weeks off.
It is also crucial to start at a low dose of Clen and gradually increase or “Ramp-up” over the cycle.
For example, a bodybuilding forum contributor suggests the following first cycle of 2 weeks Clen 2 weeks ECA:
Some sources indicate no tapering is necessary, while others recommend it. Begin the ECA stack Day 17, using the same precautions used with Clenbuterol, paying attention to any side effects.
After completing the first cycle, start the second two-week on/two week off cycle. Consider starting the second cycle on day 1 at 60mcg if there are no serious side effects.
Users who start at high doses are most likely to experience more severe side effects, compared to those who start at a lower dose and only increase when able to tolerate any side effects.
Neither Clen nor Ephedrine have current approval for bodybuilding, performance enhancing or weight loss use in the USA, possibly due to the long half life of Clen and possible side effects.
However, it is used to enhance fat free lean mass in livestock.
Deciding whether to use Clen or Ephedrine (or to stack Clenbuterol and ECA) is an individual decision, weighing benefits, risks and other facts related to the two substances.Black Mamba HyperrushBlack Spider 25BronkaidDiablos ECA Fire CapsECA Extreme Fat BurnerEphedra Outlet ReviewGreen Stinger EphedraHellfire Eph 150Hydroxycut with EphedraKaizen EphedrineLipodrene HardcoreLipodrene with EphedraMetabolife 356 with EphedraMetabothinMethyldrene 25MethylzeneMini Thin Ephedrizine 25 mgOctadrenePrimatene EphedrineRed Volt EphedraRhino Rush EphedraRipped Fuel with EphedraRipped PowderStacker 3 with EphedraUltimate BurnXenadrene with EphedraYellow Bullet EphedraYellow Devils
