    How did you use it?:Everyday

    "Very puzzling. The label reads don't take longer that 8 weeks but says okay to take for 2 years.
    I took 5 gm per day for 6 weeks, rested one week then went back on with 6 gm per day taken in 3 doses with meals. I am 78 years old, cut my Cialis dosage in half and still happy with frequency of morning wood.
    I know that this product can cause diahrea and I don't experience that. But I do have watery stool and I don't know if this product caused it and doubt it because I had that problem before taking L-Arginine.
    I have read blogs where guys are reporting that 5 grams per day is effective for ED and doesn't seem to have a problem with Cialis. My experience supports those statements.
    I hope that the 8 week limit is false because I really like the boost to libido that comes with 6 grams per day. refers to dosages as high as 30 grams per day.
    I hope this information helps someone and I would really like to hear from the manufacture"
