Why does sermorelin burn when injected?

Discomfort where the needle goes in is often reported with mixed peptide liquids in general. It can come from the water used, how strong the mix is, or personal sensitivity, and is not unique to sermorelin. The studies of sermorelin in people that this site reviewed do not measure injection-site feeling. So this is a general peptide experience, not a recorded finding about sermorelin itself.
