Triptorelin (2mg)

What is Triptorelin?

A potent synthetic GnRH decapeptide agonist used in HPG-axis research and FDA-approved for prostate cancer and central precocious puberty.

Listed vial contents: 2mg. These are supplied quantities, not administration doses. Current pricing and availability are shown in the strength selector.

What mechanisms are being studied?

Triptorelin is a synthetic decapeptide analog of GnRH with a D-tryptophan substitution at position 6 that increases receptor affinity and resistance to degradation. Pulsatile administration stimulates LH/FSH release, while sustained dosing produces an initial flare followed by profound HPG-axis suppression — the mechanism exploited in oncology.

What are the research questions?

• Prostate cancer (depot): FDA-approved as Trelstar® and Decapeptyl® for androgen deprivation therapy.
• Central precocious puberty: Suppresses premature gonadotropin release.
• Endometriosis and assisted reproduction: Used in controlled ovarian-stimulation protocols.
• HPG axis restart research: Investigated as a single-bolus 'restart' protocol after long-cycle androgen suppression.

What does the published work describe?

Heyns CF et al. (BJU Int 2003) — sustained castrate testosterone levels with depot formulations. Single-bolus 'restart' literature consists primarily of small clinical case series with mixed outcomes.

What are the limits of this evidence?

The research described concerns the cited experimental materials and models, not proof that this supplied vial is a treatment. Cell or animal findings do not establish human benefits. Clinical findings, where cited, apply to the tested formulation and population; they do not validate this research product for human use.

How should I check lot documentation?

Match the product, strength and lot to an original analysis document. Literature describes experimental findings; it does not verify the contents of this inventory. A report is evidence only for the product, strength and lot it names.

How is Triptorelin handled in the lab?

Plan a Triptorelin stock solution from the sequence, the listed molecular weight (1311.45 g/mol) and, when reported for the same lot, net peptide content. Test-dissolve a small portion first, store the powder sealed, cold and dry, and split solutions into single-use aliquots. These are laboratory handling notes, not administration guidance.

• Peptide solubility: choosing a lab solvent
• Stock solution molarity and concentration math
• Lyophilized storage, aliquoting and freeze-thaw
• Fmoc vs Boc synthesis and the impurities they leave
