Hello, I'm DanCherek. An edit you recently made to Insulin-like growth factor seemed to be a test and has been removed. If you want more practice editing, the sandbox is the best place to do so. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thank you. DanCherek (talk) 01:49, 28 February 2021 (UTC)
