What was insulin used for in the 1920s?

How was diabetes treated in the 1920s?
Frank et al. synthesized a guanidine compound called Synthalin in Germany and used it to treat diabetes during the 1920s. Homologs of guanidine (e.g., Synthalin) were used for a short period but were hepatotoxic, and the use of these compounds all but ended with the discovery and proliferation of insulin.
When did insulin become widely available?
By 1923, insulin had become widely available, saving countless lives around the world, and Banting and Macleod were awarded the Nobel Prize in Medicine.
How is insulin manufactured today?
Today, insulin is brewed up by microbes that have been genetically engineered with the gene for human insulin. And insulin is seldom injected with an old-fashioned syringe and needle anymore. Now there are insulin pens, pumps, test strips and other devices that improve the quality of life for diabetic patients.
Who first used insulin to treat diabetes?
