PT141

PT141 is a melanocortin receptor agonist studied for sexual dysfunction research. Activates MC3R and MC4R receptors in the central nervous system. Published research has examined its role in libido, sexual function, desire.

Yes. Kirei Clinic ships PT141 to all Canadian provinces — Ontario, British Columbia, Alberta, Quebec, Manitoba, Saskatchewan, and all territories. It's available strictly for non-clinical laboratory research purposes.

Every batch is independently tested to 99%+ purity by third-party HPLC. Mass spectrometry confirms peptide identity. A Certificate of Analysis documenting purity, molecular weight, and batch data is included with every order.

Store lyophilized PT141 at -20°C in the original sealed vial. After reconstitution with bacteriostatic water, refrigerate at 2-8°C and use within 4 weeks. Avoid repeated freeze-thaw cycles — aliquot if multiple uses are planned.

Draw bacteriostatic water into a syringe and inject slowly against the vial wall — not directly onto the powder. Swirl gently to dissolve; never shake. Common volumes are 1 mL, 2 mL, or 2.5 mL depending on the concentration needed. Let sit for a minute if not fully dissolved.

PT141 is legal to purchase in Canada for non-clinical laboratory research. It is not approved by Health Canada for therapeutic use and is not intended for human consumption. Kirei Clinic sells it strictly for research applications.

Both PT141 and melanotan-ii are used in sexual dysfunction research research but work through different mechanisms. PT141 is a melanocortin receptor agonist. Researchers often study them in parallel to compare mechanism-specific effects.

Every order includes a Certificate of Analysis (COA) with: HPLC purity results (99%+), mass spectrometry data, batch number, manufacturing date, and expiry date. This provides full traceability for research records.
