For Laboratories

Sourcing PT-141 for Research

Laboratories working on melanocortin receptors, on appetite or sexual behaviour in animals, or on testing methods usually buy PT-141 as a freeze-dried powder in sealed vials, often as bremelanotide acetate.

Our Position

PT-141.xyz does not sell PT-141 and does not test, rank or recommend sellers. The points below apply to any supplier.

What laboratories tend to check:

  • Identity: the label and paperwork should name bremelanotide (PT-141), the ring-shaped peptide of about 1,025 daltons, and not the related tanning compound.
  • Batch testing: a certificate of analysis tied to the lot number, showing HPLC purity and a mass spectrometry result.
  • Clear labelling: marked for research use only and not for human consumption.
  • Paperwork and storage: ordered through the institution, kept cold and dry, and logged according to local rules.

Even when a catalogue such as www.peptides-eu.net lists a purity figure, it is worth asking for the certificate that matches your batch.

Important
