Why are no test results published on the site?

Because there are currently no received batches or verified analytical documents linked to them. The infrastructure can publish real records after receipt and verification, but does not create placeholder batch identifiers.

What does HPLC prove?

HPLC shows how many components a sample contains and in what proportion. It does not identify them — that requires mass spectrometry.

What does mass spectrometry prove?

It compares measured mass with the value calculated for the expected sequence, confirming the molecule's composition. It does not distinguish stereoisomers.

What is tested and what it proves

A test is useful when it is clear which question it answers. Below are the questions, the methods, and the limits of each.

Current status

Moscow Peptides currently holds no verified independent analytical documents for any batch. We state this directly rather than publishing someone else's certificates or figures with no source.

Three questions, three methods

HPLCAnswers: How many components and in what proportionDoes not answer: Does not identify the components

Mass spectrometryAnswers: Whether the main component matches the expected moleculeDoes not answer: Does not distinguish stereoisomers

Peptide contentAnswers: What fraction of the powder's mass is peptideDoes not answer: Says nothing about impurities

Identity and purity are not the same

Purity answers how homogeneous a sample is. Identity answers what its main component actually is. A sample can be 99% homogeneous and still not be the expected molecule: high purity of the wrong substance is still the wrong substance.

For several catalogue items this is not an abstraction. The name TB-500 admits both full-length thymosin beta-4 and a fragment of it; CJC-1295 exists in DAC and No DAC forms; GHK and GHK-Cu are different substances. In every case measured mass settles the question, not a purity figure.

Detailed explanation

Batch traceability

An analytical result applies to a batch, not to a product name. A document with no batch number confirms that an analysis took place, but not that it relates to your vial.

Batch status

How to verify documentation

After a real batch is received, a record is created for it. Its page will show which documents exist, the status of identity and purity, and which laboratory performed the analysis. A verified document can then be opened directly.
