Product overview

PT-141 10mg/10vials is a sterile lyophilized research peptide. PT-141 (bremelanotide) is a synthetic cyclic heptapeptide and an active metabolite of Melanotan-2 from which the C-terminal amide has been removed. It is studied as a non-selective melanocortin-receptor agonist with notable activity at the central MC4R receptor, and has a substantial preclinical literature on MC4R-mediated CNS endpoints.

Independently assayed by HPLC and MS, and lot-traceable to the source preparation.

Typical research dose range

Published preclinical CNS-pharmacology protocols use PT-141 in animal models in the range of roughly 0.5-2 mg per administration, with timing keyed to the specific endpoint under investigation. Researchers should consult source literature for the specific endpoint and model organism.

Stack and pairing

PT-141 is studied alongside Melanotan-2 in comparative melanocortin-receptor pharmacology work, where the two molecules provide a contrast between pigmentation-leaning (MT-2) and CNS-leaning (PT-141) downstream profiles despite their shared receptor family.

Reconstitution and storage

Reconstitute each vial with 1-2 mL of bacteriostatic water for the target working concentration. Use sterile technique. Once reconstituted, store at 2-8 °C and use within 30 days for best stability.

Lyophilized vials should be kept refrigerated at 2-8 °C until first use. For long-term storage beyond six months, store at -20 °C in the original sealed vial. Avoid repeated freeze-thaw cycles.

Frequently asked

  • Is this product for human consumption?
    No. This product is sold strictly for laboratory research use only. It is not a drug, food, cosmetic, or dietary supplement and is not intended to diagnose, treat, cure, or prevent any disease.
  • How is purity verified?
    Every lot is independently assayed by HPLC and mass spectrometry. CoAs are issued per lot and available on request — see the certificate of analysis section above.
  • How is it shipped?
    Ships within 1 business day from our Canadian fulfillment facility, arriving 2–4 business days after dispatch. Discreet packaging. Free shipping on Canadian orders over $300 CAD.
  • What is the shelf life of an unopened vial?
    Properly stored at 2–8 °C in the original sealed vial, lyophilized peptides typically retain potency for 24 months from the date of manufacture. The expiration date is printed on each vial.

Common questions

How should I store this after receiving it?
Store unopened vials at 2–8 °C. Once reconstituted with bacteriostatic water, store at the same temperature and use within the timeframe advised in the peptide's storage guide.
Do I need bacteriostatic water?
Yes — reconstitution requires bacteriostatic water. We stock 30 mL bottles in the catalog; add one to your order if you don't have any on hand.
How long does shipping take?
Orders ship from our Canadian fulfillment centre within 24 hours and arrive in 2–4 business days via Canada Express Post.
What if the vial arrives damaged?
Contact us within 48 hours with a photograph and the lot number. We'll ship a replacement from a certified lot at no charge.
