What are hormone peptides?

Triptorelin is a long-acting analog of GnRH, the hormone at the top of the reproductive chain. A single dose triggers a burst of LH and FSH, while continuous exposure shuts the system down. Oxytocin is a nine-amino-acid hormone made in the hypothalamus, studied for labor, milk release and social bonding.

PT-141 is a cyclic melanocortin agonist developed from Melanotan II. It acts on MC4 receptors in the brain and is approved in the US as Vyleesi.

Purity and testing for our hormone peptides

Each product page shows the tested purity for the current batch, measured by HPLC with mass spectrometry, and most of our peptides test at 99% or higher. Every vial is labeled with the compound, the amount and a batch number. The certificate of analysis is filed under that number, and we’ll email it to you on request.

Store sealed vials in the freezer, or the fridge for shorter stretches, and reconstitute with sterile bacteriostatic water. Every vial page lists the concentration you’ll get for each volume. Our vial storage case keeps ten vials upright and together.
