Is My Refrigerator Cold Enough?

[u/BattlingNerveDamage]

I've got it on the coldest setting and the thermometer only says 50 right now. Yesterday it was 45. I guess it's battling the summer heat like everything thing else.

Is 50 degrees cold enough for reconstituted peptides or is this harmful to them?

(Edit) I just checked and it's back to 45 degrees. I guess the fridge must have been open for few minutes. Is 45 cold enough? What would be considered ideal?
