I thought so, but thought it better not to be contradicting the 'expert'!
He also strongly advised me to take statins (which I have always declined and will continue to do). He said I am at high risk due to my cholesterol levels. Though my cholesterol ratio is only 3.28 which is supposed to be healthy. He also told me to re-use needles several times and put the cap back on each time, which contradicts the manufacturer instructions completely, but maybe this is NHS practice, who knows.
I really wouldn't recommend reusing the same needle several times - once it gets blunt it will bloody hurt when you inject!
Once or twice is fine though.
