Independent Laboratory Testing | Signalyn Bio
When evaluating a research peptide supplier, a purity percentage alone doesn't tell the whole story.
That's why we believe independent testing, batch identification, and access to original laboratory reports are important parts of supplier transparency.
We're sharing three Janoshik Analytical reports covering Retatrutide, Tirzepatide, and BPC-157.
These reports are provided for reference and independent verification.
Please refer to the original report for the sample identification, batch information, analytical methods, and reported results.
The original document provides the laboratory's reported analytical findings for the submitted sample.
Each report should be evaluated using its own laboratory reference number, sample information, analytical methods, and verification details.

We'll continue updating our testing documentation as additional batch-specific reports become available.
Important: These results apply only to the samples tested. They do not establish identical purity, identity, or content across other batches or individual vials.
All materials are intended for laboratory research use only. Not for human or veterinary use.

How to Verify the Reports
We encourage readers to review the original laboratory documents rather than relying solely on screenshots or summarized purity percentages.Each report should be evaluated using its own laboratory reference number, sample information, analytical methods, and verification details.
