half the tab for the first dosage, take it right upon waking up (see if you are extremely sensitive to it)
people are going to tell you different dosages but for a first time around i wouldnt go for more than 20 days and higher than 75mcgs
people do a pyramid usually
so like 25 25 25 25 then 50 50 50 50 then 75 75 75 75 then 50 50 50 50 then 25 25 25 25 then EC after for like 2 weeks.
Make sure you are getting potassium in your diet (bananas!) and increase your Omega 3 intake, Q10 would also be good for keep BP and Chol at bay
best of luck
