DESCRIPTION

PT-141 is a synthetic cyclic heptapeptide studied as a melanocortin receptor agonist in receptor signalling and neuroendocrine pathway models. Supplied as lyophilised freeze-dried powder requiring reconstitution prior to laboratory use. All products supplied by Nilah Labs are strictly for in-vitro laboratory research use only. Not for human consumption, medical use, or clinical application.


TESTING & COA Plus

All compounds supplied by Nilah Labs are sourced exclusively from audited partners and subject to independent third-party testing across our range. All third-party testing is conducted by independent laboratories based in the UK.

Our testing standard requires both HPLC (High Performance Liquid Chromatography) and Mass Spectrometry analysis. HPLC determines purity percentage. Mass Spectrometry confirms molecular identity, verifying that the compound is exactly what the label states. Purity alone does not confirm identity. Both are required.

We set a minimum purity threshold of 99% across all compounds. If a compound does not meet this standard it is not listed.

Where a Certificate of Analysis is available for the current batch it is published directly on this product page. This is a document issued by an independent UK testing laboratory, not a manufacturer-issued certificate. We do not fabricate documentation and we do not reuse COAs from previous batches.

All suppliers we work with are vetted before we place an order. We do not list compounds from unverified sources.

 RESEARCH OVERVIEW Plus

PT-141, also known as Bremelanotide, is a synthetic cyclic heptapeptide analogue derived from melanocortin peptide research. It functions primarily as a melanocortin receptor agonist with activity observed at MC1R, MC3R, MC4R, and MC5R receptor subtypes in preclinical receptor-binding models. PT-141 has been investigated in neuroendocrine signalling research, melanocortin pathway modulation studies, and central receptor activation models associated with hypothalamic signalling mechanisms.

Preclinical investigations have evaluated PT-141 in receptor affinity assays, intracellular cyclic AMP pathway analysis, and animal-based melanocortin signalling studies. Research has also explored its interaction with neuropeptide-mediated communication pathways and autonomic signalling systems within controlled laboratory environments. Current published data remains centred on preclinical and experimental laboratory research, with ongoing investigation into melanocortin receptor pharmacology and peptide-receptor interaction dynamics.

PT-141 supplied by Nilah Labs is manufactured for institutional and laboratory research applications and is provided as a lyophilised freeze-dried powder requiring reconstitution prior to laboratory use. Each batch undergoes analytical verification through HPLC and Mass Spectrometry testing, with certificate of analysis documentation available for research procurement requirements.

 FAQ Plus

Q1. What is PT-141 and what has it been studied for in research settings?
PT-141 is a synthetic melanocortin receptor agonist studied in neuroendocrine signalling and receptor interaction models. Research has focused on melanocortin pathway activity, intracellular signalling cascades, and receptor-binding dynamics in controlled laboratory environments. Current literature primarily involves preclinical and in-vitro investigations.

Q2. How should PT-141 be handled and reconstituted in a laboratory setting?
PT-141 is supplied as a lyophilised freeze-dried powder and requires reconstitution prior to laboratory application. Standard peptide handling procedures should be followed using sterile laboratory techniques and calibrated preparation protocols. Researchers should minimise repeated freeze-thaw exposure to preserve analytical stability.

Q3. What are the recommended storage conditions for PT-141?
PT-141 should be stored at −20°C in a dry and light-protected environment. Proper cold-chain storage conditions support peptide integrity and long-term analytical consistency. Reconstituted material should be handled according to established laboratory stability procedures.

Q4. What is the legal status of PT-141 in the United Kingdom?
PT-141 is supplied in the United Kingdom for legitimate in-vitro laboratory research purposes. Research compounds are subject to institutional handling requirements and applicable laboratory regulations. Researchers and procurement departments are responsible for ensuring compliance with local regulatory frameworks.

Q5. How is purity verified and what documentation is available?
Each batch of PT-141 undergoes analytical verification using HPLC and Mass Spectrometry testing methodologies. Certificate of analysis documentation is available to support laboratory procurement and quality assurance requirements. Analytical testing is performed to confirm purity, identity, and batch consistency prior to release.

Why Nilah Labs?

The Standard Others Should Be Held To.

Most UK peptide suppliers rely on self-certification and generic COAs. We don't. Compounds are independently tested by UK-based third-party laboratories across our range, so you always know exactly what you're working with.
