Triptorelin 2mg (30 Vials / Kit)

Triptorelin at a glance

Triptorelin is a decapeptide analog of gonadotropin-releasing hormone, the hypothalamic signal that controls pituitary release of LH and FSH. Replacing the glycine at position six with D-tryptophan makes the molecule far more resistant to enzymatic breakdown and increases its receptor affinity compared with the natural hormone, while the C-terminal glycinamide is retained. In approved medicines it is formulated as acetate or pamoate salts, including sustained-release preparations.

Price and availability

Jinlu Peptides lists this kit of 30 vials at 2mg each (60 mg in total), shipped from China. The price is $159.30, or $2.66 per milligram of peptide. Of the 2 Triptorelin listings on the marketplace, from 2 brands, this is the lowest price per mg. Funds stay in escrow and are released to Jinlu Peptides only when you mark the order as received.

What it is studied for

Triptorelin binds the GnRH receptor on pituitary gonadotroph cells. Initial binding stimulates a surge in LH and FSH release, often called the flare effect, along with a temporary rise in testosterone or estradiol. With sustained receptor occupancy, gonadotrophs become desensitized and receptor numbers fall, so LH and FSH output drops and gonadal sex-steroid production is suppressed to very low levels. That paradoxical outcome, stimulation turning into suppression, is the basis for its clinical use and for research models of reversible hormonal suppression.

Research and regulatory status

Triptorelin is an established prescription medicine, approved in the US, Europe and elsewhere for advanced prostate cancer, and in various regions for endometriosis, uterine fibroids, central precocious puberty and as part of assisted-reproduction protocols. Its clinical pharmacology is documented in decades of trials. Research use covers reproductive endocrinology and hormone-dependent cancer models. Research-grade powder is not an approved formulation and is unrelated to those products' regulatory approvals.

Checking the lab data

A credible report should confirm identity by mass spectrometry matching the calculated mass of the triptorelin decapeptide, and state the salt form, usually acetate, since counter-ions affect weight-based content. HPLC purity should come from a lot-specific chromatogram, and chiral analysis confirming the D-tryptophan configuration adds confidence, because an L-isomer impurity would have the same mass. The lyophilized cake should be white.

Storage and preparation

Freeze-dried peptide keeps best sealed, cold and dark. Once it has been dissolved, refrigerate it, avoid repeated warming and follow the stability limits in your study protocol.

Concentration arithmetic: one 2 mg vial dissolved in 2 mL gives 1 mg/mL, or 2 mg/mL in 1 mL. The Research Lab calculator in your dashboard handles any other volume.
