Why Do Peptides Gel? (Tesamorelin & Kisspeptin Explained)

Some peptides, including Tesamorelin and Kisspeptin, can form a gel-like consistency or clump during reconstitution. This occurs due to their natural tendency to self-associate, especially when solvent is added too quickly, temperatures are too low, or concentrations are too high. While this behavior can seem concerning, it is typically a physical property of the peptide—not a sign of poor quality.

To prevent gelling, it’s important to add solvent slowly, avoid shaking, use room-temperature diluent, and allow enough time for the peptide to dissolve naturally. Proper handling techniques significantly improve solubility and ensure more consistent research outcomes.
