Hello. I noticed that you made one or more changes to an article, Gamma-Hydroxybutyric acid, but you didn't provide a reliable source. It's been removed and archived in the page history for now, but if you'd like to include a citation and re-add it, please do so! If you need guidance on referencing, please see the referencing for beginners tutorial. Thank you. DMacks (talk) 01:29, 7 September 2018 (UTC)
