I've been using the bronkaid caffeine stack twice daily to make up 50mg of ephedrine and 400 caffeine. I have stop getting the initial jittery feeling I used to get and the energy boost has worn off greatly. Should I up it to one more serving a day? And if so how far appart should I space it. Also wondering how long it takes for u to notice the fat burn from ephedrine. I've noticed slight change but I feel like its part of my diet
