ECA STACK

Everyone who is planning to use ECA stack.. i have few points to convey1) Its a very potent fat burner.2) you will feel very high heart beat after taking it. I have been working out from last 5 years and started taking supplements like protein, preoprkout and fat burners and vitamins from last 1 year. Never felt any kind of side effects. But this ECA stack is crazy. I felt like dying from heart attack, and nausea while grinding. Extreme headache and got extreme pump while working out. So please beware if you are not used to any kind of fat burners. The side affect lasted for entire day. In the evening i felt little relaxed.After one day of use i stopped using it because it did not suited me and out of control heart rate and nausea.Beginners please do not use. Strictly only for professional athletes.Peace ✌️
