Not if you’re concerned about cancer prevention or treatment. I’ve been taking a weekly dose for a year, to prevent respiratory infection. I have emphysema, so I’ll take any advantage I can. Unfortunately I’d have to find a compounding pharmacy in neighboring TN, which would entail most of a day’s travel. I ordered mine from India.
How many milligrams are you taking? I have some horse paste, but I have no idea how many milligrams to take.
