I have chosen to make some changes to this blog:
1 I have instigated a rolling program of deleting older blogs. The blog is not meant as a formal reference site and this is to ensure that the information in the blog remains up to date
2 I have unfortunately had to prevent user comments by external users. Whilst some were really interesting they are outnumbered over 20:1 by comments solely sent with the purpose of redirecting readers to the commenter’s web pages. The vast majority of these are commercial pages selling products (such as peptides). These were taking too much of my time to filter out.
