What are hormone peptides?

Kisspeptin sits at the top of the reproductive hormone chain. It switches on GnRH neurons in the hypothalamus, which then drive LH and FSH release from the pituitary. Oxytocin is the nine-amino-acid hormone behind labor, milk release and social bonding.

PT-141 (bremelanotide) is a melanocortin agonist derived from Melanotan 2 that acts on MC4 receptors in the brain. A version of it is approved in the US for low sexual desire in premenopausal women.

How to choose hormone peptides

Kisspeptin suits studies of the reproductive axis, oxytocin suits social behavior and smooth muscle work, and PT-141 suits melanocortin research.

All three are freeze-dried vials. Oxytocin is the most heat-sensitive, so keep it cold once it’s mixed.

Planning a hormone study

Hormone signaling follows daily rhythms, so sample at the same time of day across every group. Many reproductive hormones are released in pulses, which means a single sample can miss the peak.

Keep peptide hormones cold once mixed and use them within the window on the product page. Oxytocin in particular is sensitive to heat.

Quality and handling for our hormone peptides

Every product in this range carries a label with the product name and amount. If your lab needs batch paperwork on file, contact Peptira support before you order and ask what’s available for the current batch. Labs that check incoming material themselves usually confirm identity by mass spectrometry and measure purity by HPLC.

Store sealed vials in the freezer and reconstitute with bacteriostatic water. Every vial page lists the concentration you’ll get for each volume, and our 10 vial kit case keeps vials upright in the fridge.

Ordering and shipping
