I have been for 7 weeks on test prop, and all thistime I had very bad headaches. My dosage is 250 three times per week,and I use arimidex at 0.25 mgs twice per week. Have to say that Istarted taking it from week 6 on, so it can not be the cause of theproblem, because the headaches were from the start of the cycle. Thisis not dehydration because I drink plenty of water. Did anyoneexperience a similar problem before?
