Should peptides be injected cold?

Injecting a solution straight from the refrigerator is documented, in the insulin injection literature, to make an injection more uncomfortable, which is why many people keep the vial currently in use at room temperature rather than fully refrigerated. This is a comfort question, not a safety one, and it has not been tested specifically for the compounds this site tracks.

Part of injecting: sites, needles and safety. Subcutaneous vs intramuscular, where people inject, rotation and lipohypertrophy, needle gauge, aseptic technique, why it stings, and sharps disposal. Full walkthrough at /injecting.
