Does Glyphosate concentrate lose its efficacy over time?

I have recently been using a bottle of Murphy Tumbleweed Gel discovered
in a shed clear out. It must be at least 17 years old and might be as
much as 24.

Works fine.

The early effects of Glyphosate are subtle. Serious distress may
takeover 2 weeks to show. However, within a week, expect the weeds to
look *slightly* dull, off-colour and not growing as fast if at all.
