What this peptide is for

Melanocortin receptor agonist.

PT-141 (Bremelanotide, CAS 189691-06-3) is a cyclic heptapeptide that activates MC3R and MC4R receptors in the CNS. Research has focused on its role in sexual motivation and arousal in both male and female subjects, independent of vascular action. Formula C50H68N14O10, MW 1025.18 g/mol. Use under clinical guidance.

Questions, answered plainly

Everything worth asking before you order.

Shipping, storage, quality, and when to speak to a clinician — without the runaround.

What proof of quality comes with my order?

Every batch ships with a batch code printed on the vial. The matching third-party certificate of analysis — identity, HPLC purity, and mass-spec results — is linked on the product page and also available from your order page after purchase.

Should I speak to a clinician before using a peptide?

We recommend it — especially if you are pregnant, nursing, managing a medical condition, or combining peptides with prescribed medication. Our product pages are educational. They are not medical advice and they do not replace a conversation with a qualified practitioner.

When will my order ship and arrive?

Orders placed before 14:00 CET Monday–Friday ship the same business day from our European fulfilment centre in The Hague, Netherlands. Standard tracked EU delivery arrives in 2–4 business days; express options are available at checkout.
