My peptide got warm during shipping. Is it ruined?

Dry, freeze-dried peptides usually handle a short spell of warmth during normal shipping without much breakdown. That is why sellers often ship them without ice. A mixed (liquid) peptide is different and should never be shipped or left warm. Once a dry vial arrives, what matters is keeping it cold from then on.
