Lab tests
All products are manufactured by Alpha BioPharma and tested by the independent laboratory Janoshik Analytical. Each report below links to the original on janoshik.com.
Independent lab
Tested by Janoshik Analytical — not owned by the manufacturer or by Peptidewinkel.
Date per report
Each result shows the test date, so you can see how recent it is.
Transparency first
Every test result is publicly accessible so you can verify yourself what you are buying.
Our approach
Why we test
Who manufactures: Alpha BioPharma, our sole manufacturer. Peptidewinkel does not manufacture itself; we purchase, verify the documentation and ship.
Who tests: Janoshik Analytical, an independent analytical laboratory. The commission and the samples come from Alpha BioPharma.
What "independent" means: the lab is not owned by the manufacturer or by Peptidewinkel and publishes the report itself. You can verify every report on janoshik.com via the link and the unique code in the URL.
Method: Janoshik measures purity with HPLC and, where stated, the content in mg or IU per vial. The exact method and sample are in the original report.
Per result we show: product, batch (if stated in the report), test date, measured result and the link to the report. Not every product and not every batch has been tested; if a product does not appear here, no report exists (yet).
