On my side, whenever I buy glycin, I immediately use it to make stock solutions for the developers I need (Agfa 72, 115, and 130).

After a good year at room temp, these stock solutions are still working fine as the first day.

Thank you very much for your contribution. Hubl's Paste is renowned for its shelf life, but I never found anything about Agfa 72's shelf life. Until now. Thank you very much for that. A year, or a little bit more, is more than enough for my needs.

If you have Hubl's Paste and are happy with its shelf life, you should be able to make the working solution of Agfa 72 from it by adding the differential Sulphite and Carbonate to the working solution. See this to get an idea of what these differential amounts are.
