Sermorelin is a GHRH(1-29) analog (MW ~3,357.9 Da) with a longer regulatory history than most research peptides — it held FDA approval for pediatric GH deficiency before a commercial (not safety) withdrawal. Research-grade material is supplied as a lyophilized powder.
What to Look for When Sourcing Sermorelin
Require a third-party COA (HPLC and mass spectrometry) confirming ≥98% purity and the ~3,357.9 Da molecular weight. Confirm the vendor is not marketing research material as an approved clinical product.
Typical Price Range
Research-grade Sermorelin typically costs about $25–$45 per vial.
Storage and Handling
Store lyophilized Sermorelin at 2–8°C, or frozen for long-term storage. Reconstituted peptide is dosed at bedtime in research protocols and must be refrigerated between uses.
Red Flags to Avoid
Missing COAs, clinical-drug claims, prices far below market, and human-use claims.
