The other half of the closest pair we test. Melanotan II and PT-141 sit one dalton apart, and PT-141 is what Melanotan II becomes as it breaks down.

Order this testA cyclic seven-residue peptide, the C-terminal amide form. No approved pharmaceutical version exists anywhere, so there is no reference product against which a vial can be checked.
PT-141 is the acid form of this molecule and a dalton heavier. It is also what Melanotan II degrades into. So a vial can drift toward PT-141 on the shelf, meaning the ratio between the two says something about how the material has been stored, not only how it was made.
Melanotan II has never been approved in any jurisdiction. There is no legitimate manufacturing chain, no pharmacopoeial monograph, and nothing official to compare a sample against. The analysis is the only evidence there is.
As with PT-141, incomplete cyclisation leaves linear material 18 daltons heavier. It is a routine synthesis failure and a routine finding.
1024.2 vs 1025.2
Melanotan II against PT-141 — one dalton apart, about 0.1%
The gap between them is one nitrogen-for-oxygen swap at the end of the chain. Why weighing the molecule is the only way to tell.
One unopened vial. Detailed posting instructions arrive with your order confirmation, immediately after you pay.
No. Lyophilised peptides travel safely at room temperature, which is how nearly all samples reach us.
An independent Ontario laboratory. Every certificate we issue names the facility that ran it — we are a testing service, not a laboratory, and we would rather say so than let you find out from the report.
You get the result. We do not soften findings, and we do not charge differently depending on what the analysis shows.
Yes. Every certificate carries an identifier that anyone can check against our records, including the vendor you bought from.
