Lecirelin is a synthetic gonadotropin-releasing hormone (GnRH) analogue used in veterinary reproductive management programs. Supplied as a lyophilized peptide API , it supports formulation of veterinary products requiring controlled stimulation of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) release.

The material is manufactured to veterinary API quality standards and supported with full batch documentation for formulation development, scale-up, and commercial production.
