Triptorelin (GnRH) 2mg Overview

Triptorelin 2mg from Peptide Science is the synthetic stability-modified decapeptide analog of native gonadotropin-releasing hormone (GnRH), supplied as a lyophilised vial for in-vitro and preclinical HPG-axis research. The compound differs from native GnRH by a D-tryptophan substitution at position 6, which extends the in-vitro half-life by reducing enzymatic degradation.

Compound Class and Mechanism

Triptorelin has the sequence pGlu-His-Trp-Ser-Tyr-D-Trp-Leu-Arg-Pro-Gly-NH2, with the position-6 D-tryptophan substitution replacing the native glycine. The D-amino-acid substitution blocks the primary enzymatic cleavage site between residues 6 and 7 used by GnRH-degrading endopeptidases, giving the analog substantially longer in-vitro half-life than the native gonadorelin sequence. The peptide retains full binding affinity at the GnRH receptor and produces sustained activation followed by receptor desensitisation in extended cell-culture protocols.

Reconstitution and Handling

The lyophilised vial reconstitutes with bacteriostatic water at the working concentration set by the principal investigator. Aliquoting reconstituted stock for single-use frozen storage is the standard preclinical handling practice cited in peptide-research literature.

Quality and Shipping

Each batch passes HPLC at greater than 99 percent purity, with mass-spectrometry identity confirmation. A Certificate of Analysis accompanies every order. Material is filled in a US laboratory under ISO 9001:2015-aligned quality systems and dispatched in temperature-monitored insulated packaging via overnight or two-day courier.
