What is PT-141?
Cyclic alpha-MSH analog studied through melanocortin MC3R and MC4R signalling.
PT-141 is a stabilised cyclic heptapeptide analog of alpha-melanocyte-stimulating hormone. Published pharmacology characterises it as a non-selective melanocortin receptor agonist with the studied activity attributed largely to MC3R and MC4R, receptors expressed predominantly in the central nervous system rather than peripheral tissue. This vial is supplied as a lyophilised powder, which is the format most laboratory protocols specify because the dry peptide is stable at -20°C and the researcher controls the final concentration. Reconstitute with bacteriostatic water down the inside wall of the vial, swirl rather than shake, and calculate concentration from the 10 mg vial mass using our reconstitution calculator. Each batch carries a reference that can be matched against the record on our lab results page. For research purposes only, not for human consumption.

How is PT-141 stored and handled?
Storage
Store lyophilized vials at -20°C, protected from light. Once reconstituted, refrigerate at 2-8°C and use within the recommended window.
Reconstitution
Use bacteriostatic water; add slowly down the inside wall of the vial. Swirl to dissolve, never shake. See the in-house peptide calculator for concentration (mg/ml) and syringe units (IU on a U-100 syringe).
For research use only

All research guides- How to Store and Handle Research PeptidesLyophilised research peptides are stored in the refrigerator at 2 to 8 °C, or frozen at -20 °C for longer storage, sealed and protected from light. After reconstitution with [bacteriostatic water](/product/bacteriostatic-water-10ml) the solution is kept refrigerated, never shaken, and never refrozen.5 min read
