Is liraglutide at 6.67 mg/mL stable enough for four weeks of multi-withdrawal use?

For reference: liraglutide · 6.67 mg/mL · four weeks.

Somebody stated this to me confidently and I would like to check it before repeating it.

I would accept a well-reasoned negative answer over a poorly sourced positive one.

What would count as evidence here, and does it exist?
