EC Stack Dosages

EC Stack Dosages for Fat Loss

Talk with your doctor regarding taking EC and possible risks. Do not take EC without first seeing a doctor! A good doctor will monitor your blood pressure regularly, and check other health metrics, instead of just scolding you.

Read over ALL of the information and warnings on the EC Stack Page

The optimal dosage was determined clinically to be 20mg of ephedrine, and 200 mg of caffeine, taken 4-6 hours apart. In place of 100mg caffeine, you can drink 8 oz coffee. Instead of 200mg caffeine pills you can drink 12 oz of coffee.

NOTE: The dosage schedule below has been modified to better match how individuals are taking EC after reading over user feedback.

There is no need to cycle the EC stack. One major study on the EC stack had participants on it for 24 weeks, and fat loss did not go down over time. If you want a break, take at most 2 weeks.

If you would like to do an ECA stack, take ONE 81mg aspirin per day.
