Details
What it is
A metabolite of Melanotan 2 that has lost the C-terminal amide group, acting chiefly at MC4R and MC3R rather than across all five melanocortin receptors. Its international non-proprietary name is deliberately not printed on this site, because it names an approved medicine.
Also sold as: PT141
- As suppliedLyophilised powder.
- Into solutionBacteriostatic water.
Class: Melanocortin peptides.
Reconstitution and handling
Handling
- As suppliedLyophilised powder
- Sealed, refrigeratedMonths
- In solutionRefrigerate, use short-term
Concentration is mass divided by the volume you added. A 10mg vial made up to one millilitre of solvent gives 10mg per millilitre; to two millilitres, half that. Record the volume you used: a solution whose concentration is not written down is a solution you cannot use quantitatively.
The full procedure is on our reconstitution guide, with a concentration calculator; what is known about keeping these materials is on storage and stability. Bacteriostatic water and acetic acid are both in our catalogue and can be ordered with a product or on their own.
