Ever wonder why research peptides show up as a little puck of powder instead of a liquid? 🤔 That's because they're lyophilized.
❄️ Lyophilized = freeze-dried. The material is frozen, then the water is pulled out under a vacuum, leaving a dry powder behind.
🧱 Why it matters: with the water gone, the powder is much more stable. It holds up better over time and during shipping than a liquid would, which is why vials arrive as powder.
🧊 Stability still depends on storage. Heat, light and moisture are the enemies. Check the Storage Cheat Sheet in the Classroom (under Start Here) for the quick rules.
