What are hormone peptides?

These peptides act on the hormone signals that run reproduction and social behavior. Kisspeptin-10 triggers GnRH release in the hypothalamus, which sets off LH and FSH from the pituitary. Oxytocin acts on its own receptor in the uterus, breast tissue and brain.

PT-141 (bremelanotide) activates melanocortin receptors in the brain, mainly MC4R. An injectable form is approved as Vyleesi.

• PT-141: 10mg, $45.00

How to choose hormone peptides

Use Kisspeptin-10 for studies of the reproductive hormone axis, oxytocin for social behavior and stress models, and PT-141 for melanocortin research.

Kisspeptin-10 and oxytocin come in 2mg, 5mg and 10mg. The small vials suit short experiments, and the 10mg is cheapest per milligram.

Hormone peptides: formats and prices

There are 7 products in this range: seven single-peptide vials. Prices run from $25.00 to $110.00. Every product page lists the amount, the format and the SKU, so you can compare like for like before you order.

Lab testing for our hormone peptides

Most of our product pages carry the lab paperwork right in the photos: certificates of analysis with HPLC purity, and for many peptides an endotoxin report and an independent Janoshik test you can verify online. Where a report was run on a different vial size of the same peptide, the product page says so.

Store sealed vials in the fridge, or the freezer for long-term storage, and reconstitute with bacteriostatic water. Every vial page lists the concentration you’ll get for each volume of water.

Hormone peptides FAQ

Are your hormone peptides in stock?

Yes. Everything listed here is in stock now.

Are hormone peptides for human use?

No. Everything we sell is for laboratory research only and isn’t approved for human or veterinary use.

How do I pick a size?

Bigger vials cost less per milligram. Smaller ones make sense for short projects, since less sits open in the fridge. Each product page compares the sizes.

Do I need anything else?

Vials need bacteriostatic water to reconstitute. Capsules are ready to use.
