Hormone Peptides

Hormone Peptides for Research: Kisspeptin-10 and PT-141

This cluster includes two research peptides from different substance classes: Kisspeptin-10, a fragment of the KISS1 gene product, and PT-141 (Bremelanotide), a melanocortin peptide. Both compounds are being investigated in preclinical research and are exclusively available as research material.

Each batch at EONA undergoes double verification: a batch-specific COA from a commercial testing laboratory and an independent academic counter-verification. Purity is ≥98% by HPLC, and identity is additionally confirmed by mass spectrometry. Shipping is from the EU, without customs hurdles or delivery delays from third countries.

For research budgets, a quantity discount (1, 3, 5, or 10 vials) is available with up to 30% savings per unit. The COA for the respective lot can be accessed directly on the product page. All materials in this cluster are strictly for research purposes. Any clinical or human medical application is excluded.

Frequently Asked Questions

Which substance class do Kisspeptin-10 and PT-141 each belong to?

Kisspeptin-10 is a kisspeptin fragment and a product of the KISS1 gene. PT-141 (Bremelanotide) belongs to the class of melanocortin peptides. Both compounds are available as lyophilized research materials and are being investigated preclinically. No statement is made regarding suitability for humans.

How is purity proven and where can the batch-specific COA be found?

Each batch is tested by HPLC for a purity of at least 98%. The identity of the substance is additionally confirmed by mass spectrometry (MS). The batch-specific COA is directly linked on the respective product page and can be downloaded there.

Is the identity additionally confirmed by mass spectrometry and is this documented in the COA?

Yes. In addition to HPLC purity determination, the identity of each batch is confirmed by mass spectrometry (MS). Both results are documented in the batch-specific COA, which can be accessed on the respective product page.

What does "double verification" mean at EONA?

Verification is carried out in two independent steps: First, the commercial testing laboratory creates a batch-specific COA (HPLC + MS). Subsequently, an independent academic institution checks identity and purity as a second instance. Both results are included in the final COA. The academic institution is not named.

How should lyophilized peptides be stored correctly as research material?

Lyophilized peptides such as Kisspeptin-10 and PT-141 are stored cool (2-8 °C) and dry to preserve the peptide structure and stability of the research material. Information on reconstitution, dosage, or injection is not provided by EONA.

From which country is it shipped and how long does delivery take within the EU?

All orders are shipped from the EU. This eliminates customs formalities and delivery delays that can occur when shipping from third countries. The exact delivery time depends on the destination country and is listed on the shipping page.

Is there a quantity discount with a reduced unit price?

Yes. Both research peptides are available in quantities of 1, 3, 5, or 10 vials. With increasing quantity, the price per unit decreases by up to 30%. The respective quantity discount is shown on the product page. All materials are strictly for research purposes.

In what research context is Kisspeptin-10 investigated preclinically?

Kisspeptin-10 is investigated as a fragment of the KISS1 gene product in preclinical reproductive research. No statement is made about effects, endpoints, or suitability for humans. All materials are exclusively intended for use in research laboratories.
