HI all and thank you very much for your responces, Freedom42, thank you very much for coment and reference, Im not sure that this quotation is refering to drawing back to check you are not in a vessel? this sounds like it is referring to drawing air into the syringe prior to administration?

Please keep them coming along with any evidence you find
