What is ?
A cyclic seven-residue peptide and the chemistry of its ring.
is a synthetic cyclic heptapeptide used in melanocortin-receptor research. The ring is formed through a lactam linkage. Prism Labs lists a 10 mg lyophilized vial; batch documentation is available and sales have not opened.
01
A cyclic reference peptide
PubChem lists the reference structure as C50H69N15O9 with a molecular weight of 1024.2 g/mol. Its cyclic connectivity is part of its identity; an amino-acid list alone does not specify the full molecule.

02
Synthesis and scaffold research
A 2008 paper describes a solution-phase synthesis using a lactam-forming step. A 2022 study replaced that linkage with different chemical scaffolds to investigate receptor selectivity.
The scaffold derivatives are separate experimental materials. Their results should not be treated as properties of an ordinary vial of the parent peptide.

03
The listed research format
The catalog lists 10 mg lyophilized powder vials for laboratory research. These are labeled quantities; the batch report lists measured content separately.
For laboratory concentration arithmetic, use the reconstitution calculator. Concentration is the amount of material divided by the solution volume; it is not a dosing instruction.
Handling and storage should follow the lab's validated procedure. Read the storage guide for the differences between dry material and a prepared solution.
04
Batch documentation
The first shipment is incoming and sales are paused. Batch certificates dated October 1, 2026 are available on the product page, with identity, purity, measured content and additional test results for the reported samples.
A database structure describes a reference molecule. It does not identify a particular supplied vial, establish its salt form or replace independent batch testing.
Match the report's labeled strength and lot number, and compare identity, purity and content results separately. See how to read a peptide COA.

Questions, answered
What is ?
A synthetic cyclic seven-residue peptide used in melanocortin-receptor research.
Which sizes are listed?
10 mg lyophilized research vials.
Are sales open?
No. The incoming products are listed as coming soon with sales paused.
Is a batch report available?
Yes. The product page links batch reports dated October 1, 2026. Match the labeled strength and lot number when checking a report. Reference structures and published papers are not batch certificates.
Is it for human use?
No. Prism Labs sells it for laboratory research use only.
