"i live in the uk so we get drugs etc free. this drug is only available via a specialist at a hospital and is carefully mointored. i&#039;m 40yrs old and had painful large sports since i was 12, i have tried everything, so now i&#039;ve hit 40 and had a family decided to try it. i lasted 15 days of 20g a day. i thought at my age i would have less to worry about that a teenager. i could cope with the dry skin and cracked lips but the headaches and joint pain was horrific. i stopped taking 5 days ago but still am in constant pain &amp; have a headache have been told these side effects could last up to 30 days. i have never suffered side effects from any drugs i have taken until i took this. if you are planning to take this please consider carefully."
