Kisspeptins are peptides encoded by the KISS1 gene and are endogenous ligands for the G-protein-coupled receptor KISS1R. In neuroendocrine research, kisspeptin signaling is a principal upstream regulator of gonadotropin-releasing hormone neurons and the hypothalamic-pituitary-gonadal axis. The name can refer to several biologically active fragments, especially kisspeptin-10 and kisspeptin-54. Accurate product content therefore requires the exact sequence and isoform. Human experimental studies have examined reproductive-hormone release and ovulation-related pathways, but VESPR’s material remains research use only.

Frequently Asked Questions
All VESPR products are sold for research use only. They are not intended for human consumption, therapeutic, or diagnostic use. Our peptides are designed exclusively for controlled laboratory research, educational studies, or analytical testing. Every product label and supporting document clearly reflects this compliance standard.
Sold exclusively to qualified researchers and licensed laboratories. Sales are limited to qualified research buyers and organizations able to lawfully handle research materials for legitimate research or educational purposes, but all buyers must acknowledge and agree to VESPR research-only terms prior to completing any order. We do not sell or endorse products for personal or medical use under any circumstances.
Products are supplied in lyophilized form and should be handled using appropriate laboratory procedures and storage practices. Materials should be protected from excessive heat, moisture, and direct light exposure. For stability purposes, avoid repeated freeze-thaw cycles and follow standard laboratory handling protocols appropriate for research environments.
Because compounds are measured in milligram quantities, the contents may appear minimal or as a thin layer within the vial. This is normal for high-purity research materials. Each lot undergoes precision weighing and analytical verification using validated laboratory testing methods to confirm labeled specifications.
Each product includes a Certificate of Analysis (COA) and supporting documentation verifying identity, purity, and batch specifications. Products are processed under internal quality-control procedures with lot traceability and analytical review standards intended to support lawful laboratory and research applications.
