About PT-141
PT-141 is a synthetic melanocortin-based peptide being researched for its effects on signal transduction in the central nervous system, particularly in the pathways related to desire, motivation, mood, and autonomic balance. Unlike compounds that act through hormonal pathways, PT-141 is being researched for its direct neurological mechanism of action via melanocortin receptors.

Important questions answered by professionals
*Answered by independent medical researchers and licensed physicians
What is PT-141 as a research peptide?
PT-141 is a cyclic heptapeptide derived from the alpha-melanocyte-stimulating hormone (α-MSH). It is studied in laboratory and in-vitro research for its activity on melanocortin receptors. PT-141 is sold by MyPeptidesLab strictly for in-vitro research and has not been approved by the EMA, FDA, or any national medicines authority.
What is PT-141 studied for in research?
In preclinical and in-vitro studies, PT-141 is being researched in relation to the activation of melanocortin receptors and the subsequent cAMP signaling. Research in animal models focuses on neurological signaling pathways. Research findings are preliminary and require further validation.
What is included in the Certificate of Analysis (CoA) for PT-141?
The batch-specific CoA for PT-141 shows an HPLC purity of 99% or higher, identity confirmation via mass spectrometry, the batch number, and the net peptide content in milligrams per vial. The CoA is published on the product page so you can review it before ordering.
How do you verify the purity of peptides?
Every batch is HPLC-tested by an independent external laboratory for a purity of 99% or higher, with identity confirmation via mass spectrometry. The batch-specific Certificate of Analysis is published on every product page.
How quickly is my order delivered and which carriers do you use?
Orders placed before 15:00 CET are shipped the same business day from the Netherlands via PostNL, including on Saturdays. Delivery within the EU typically takes 2–5 business days, fully tracked. Every package is shipped in neutral, unbranded packaging with no visible references to peptides.
Does MyPeptidesLab offer bulk or wholesale orders for peptides?
Yes, we supply bulk and wholesale quantities to verified research facilities. For inquiries, please email support@mypeptideslab.com with your specifications.
