Fertirelin Powder is a synthetic GnRH (Gonadotropin-Releasing Hormone) agonist peptide, also known as LH-RH analogue, with higher biological potency than native GnRH. As a high-value pharmaceutical peptide intermediate, Fertirelin API is widely used in reproductive endocrinology research, veterinary reproductive drug development, ovarian cyst treatment research and superovulation mechanism studies for animal breeding.

Produced with optimized Fmoc solid-phase peptide synthesis technology and multi-stage gradient HPLC purification, our Fertirelin API delivers intact full-length peptide sequence, stable biological activity and consistent batch quality. This product is for R&D and manufacturing use only, not for direct clinical or veterinary administration.

Every production batch of Fertirelin API undergoes rigorous dual QC testing (HPLC + LC-MS) in HDM BIO's in-house laboratory, with an exclusive batch COA issued for all bulk procurement orders.

When sourcing Fertirelin API powder for pharmaceutical and veterinary R&D, research teams and procurement managers should verify the following core items to guarantee product quality and stable supply:

• Purity verification: Confirm ≥98% HPLC purity with official chromatogram and complete impurity profile data
• Sequence confirmation: Require LC-MS full-length peptide sequence verification to avoid truncated peptide impurities
• Quality documentation: Ensure every production batch comes with an exclusive batch COA and complete traceability records
• Manufacturing capability: Verify mature SPPS production capacity and GMP-aligned quality systems to avoid delivery delays
• Export support: Confirm full set of regulatory documents and professional technical support for global customs clearance

Fertirelin is a structurally optimized synthetic GnRH analogue with strict synthesis and purification technical barriers. Its modified amino acid sequence requires precise coupling control, making it a high-threshold product in reproductive peptide API manufacturing.

Key production challenges include precise sequence coupling to avoid truncated impurities, strict purification to separate structural analogs, and stable activity control for consistent research results. HDM BIO adopts optimized SPPS coupling technology and multi-stage gradient HPLC purification, with full-process LC-MS structural verification for each batch to ensure consistent full-length sequence and batch quality.

Fertirelin Powder is a synthetic GnRH agonist peptide that activates pituitary GnRH receptors and stimulates LH and FSH secretion. It is mainly used for veterinary reproductive research and endocrine mechanism studies.

As a high-potency GnRH receptor agonist, Fertirelin specifically binds to pituitary GnRH receptors, stimulating the secretion of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) to regulate reproductive endocrine cycles. It is widely used in superovulation induction, ovarian follicular cyst improvement and reproductive hormone mechanism research, providing a reliable experimental tool for veterinary drug development and animal breeding technology optimization.

Different GnRH agonist and antagonist peptides have distinct potency and application scenarios, helping R&D teams select suitable raw materials for targeted projects.
