Hey, people. I was simply wondering how long would pre-loaded Melanotan 2 insulin syringes last in the freezer before they start losing potency?
Also, what is the correct way of pre loading syringes for freezing? Should I leave some air in there or not? I am thinking that if I draw the peptide without any air then the insulin syringe might crack when it freezes. But if I draw air into the syringe then there is a chance of bacterial growth.
