What purity are Bastion Peptides products?

All peptides from Bastion Peptides are independently verified at ≥99% purity by Janoshik Analytical using reverse-phase HPLC and LC-MS confirmation. Batch-specific Certificates of Analysis are available through the COA Lookup on our Resources page.

What form do Bastion Peptides products come in?

All peptides are supplied as lyophilized (freeze-dried) powder in sealed, individually labeled vials. Lyophilization extends shelf life and protects peptide integrity during shipping and storage.

Is a Certificate of Analysis available?

Yes. A batch-specific Certificate of Analysis from Janoshik Analytical is available for every Bastion Peptides product through the COA Lookup tool on the Resources page.

How should research peptides be stored?

Store lyophilized peptides at −20°C. After reconstitution with bacteriostatic water, store at 2–8°C and use within 28 days. Avoid exposure to heat, light, and repeated freeze-thaw cycles.

Overview

Sermorelin (GHRH 1-29 NH₂) is a synthetic 29 amino acid peptide comprising the biologically active N-terminal segment of endogenous growth hormone-releasing hormone (GHRH). It acts directly on pituitary somatotroph cells to stimulate endogenous GH secretion in a physiologically regulated manner. As the shortest fully active GHRH fragment, Sermorelin is a foundational research tool for studying the GHRH receptor, somatotroph function, and the hypothalamic-pituitary-somatotropic axis.
