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.

Everything about this feels professional - from the site to the packaging to the paperwork. Purity assay matches what is on the label. Will keep ordering.
Documentation is what sold me. Independent CoA per batch, clean HPLC traces. Reconstitution behaved exactly as expected. Solid supplier for research use.
Clean product, no discoloration, correct fill. Certificate of analysis was in the box AND emailed. Very straightforward experience.
Third order from MyPeptides. Purity and appearance are consistent across batches. The paperwork is genuinely useful - mass, structure and CAS all included.
Really impressed with the packaging quality. Everything double-boxed, insulated and clearly labelled. Same day dispatch worked as promised.
