ECY Stack: Ephedrine, Caffeine, and Yohimbine for Fat Burning

A lot people come to this blog looking for information on the ECA Stack (ephedrine, caffeine, and aspirin) and for Yohimbine HCL.  Both are effective supplements, but I will repeat something I’ve said before–don’t take ephedrine and yohimbine together.

primaforce-yohimbineI’ll explain the issue just in case you haven’t read either post: ephedrine is a beta-agonist, meaning it stimulates beta receptor sites.  Yohimbine is an alpha receptor antagonist, meaning it temporarily blocks alpha receptors (“stubborn” fat tends to have more of these alpha receptors, so “turning them off” temporarily can coax them to release their stores).

The problem is your heart has both beta and alpha receptor sites.  Taking both of these drugs at the same time can be kind of like pushing the gas pedal and the brake at the same time.  There is a real risk of a dangerous increase in heart rate and blood pressure.  

Here are the two options I would consider:

1. Use the ECA stack until you get relatively lean, then switch to yohimbine, or

2. Spread the doses out enough for one to wear off.  You could take yohimbine/caffeine, for example, before doing some fasted cardio in the morning then take the EC stack four or five hours later.

Just be careful and use common sense.
