Product overview
PT-141 10 mg Research Material
PT-141, also known as bremelanotide, is a synthetic cyclic peptide analogue of alpha-melanocyte-stimulating hormone. Scientific literature describes it as a melanocortin-receptor agonist, with research commonly discussing activity at MC3R and MC4R.
This Peptora product is supplied as lyophilized peptide material with a labelled quantity of 10 mg per vial. Elementrix reports a batch-average net content of 10.34 mg across three sampled vials.
Published studies listed below are provided strictly as scientific background. They do not establish that Peptora’s material is suitable for clinical use, and they are not instructions or recommendations for human or veterinary use.

Batch documentation
Traceable From Product to Certificate
The product, batch identifier and Elementrix report are presented together so researchers can review the applicable certificate before ordering.
- ✓ Batch-specific COA available online
- ✓ Direct Elementrix verification link
- ✓ Reported purity, identity and net content
Expanded third-party review
More Than a Purity Percentage
This batch certificate reports identity, net content, sterility, endotoxin, heavy metals and fentanyl-presence analysis alongside purity—providing seven documented checkpoints.
The Peptora testing difference
We Test Beyond Purity
A purity percentage is only one part of a meaningful batch review. For batch PTB-260714-A2, Elementrix also reports identity, net content, sterility, endotoxin, heavy metals and fentanyl-presence analysis.
✓ Net content
✓ LC-MS identity
✓ Sterility
✓ Endotoxin
✓ Heavy metals
✓ Fentanyl presence
One batch-specific Elementrix certificate with direct verification.
What the expanded panel covers
Purity and content
RP-HPLC purity of 99.24% and average net content of 10.34 mg are reported, including individual results from three sampled vials.
Identity confirmation
LC-MS analysis is reported as confirming the identity of the material evaluated by Elementrix.
Sterility and endotoxin
The certificate reports no growth for sterility and an endotoxin result of 0.16 EU/mL.
Heavy-metals screening
Arsenic, cadmium, lead and mercury are itemized at 0.028, 0.023, 0.015 and 0.034 ppm, with overall heavy metals below 0.1 ppm.
Fentanyl-presence analysis
The additional fentanyl-presence analysis is reported as not detected for the sample evaluated.
Direct verification
Report ELX-20260714-14724 can be checked through Elementrix so the certificate is not dependent on Peptora’s description alone.
