Very impressed with the CoA
Ordered late Monday, arrived Wednesday morning in the UK. Packaging was cold-protected and every vial sealed correctly. CoA matched the batch number on the label.

About this compound
Deslorelin
Synthetic GnRH agonist
Deslorelin is a synthetic nonapeptide GnRH agonist with higher receptor potency and stability than native GnRH. It is a reference ligand in GnRH-receptor and reproductive-axis research.
GnRH-receptor agonism is studied in vitro for gonadotropin-release and receptor-desensitisation signalling.

Deslorelin is a synthetic GnRH agonist, supplied by MyPeptides for laboratory research use only.
Deslorelin is a synthetic GnRH agonist. MyPeptides supplies it as a lyophilised 5 mg vial for in vitro laboratory research, HPLC assayed at ≥99% purity with a signed certificate of analysis on every batch.
Researchers reach for Deslorelin in gonadotropin-suppression and reproductive-endocrine research. It is offered strictly for laboratory investigation — no personal-use claims, no dosing guidance, and no framing as a medicine.
The point of buying research grade rather than generic material is documentation. Every Deslorelin order carries lot-specific HPLC and mass-spec data, so the compound in your protocol matches the compound named on the paperwork. Modified backbone gives sustained agonism vs native GnRH.
