New: endotoxin results

The batch is complete: all 17 analyses are back, including the three the lab missed in its first run (BPC-157, Tesamorelin and GHK-Cu). The 11 peptides now carry an endotoxin figure as well, all between 3.61 and 6.82 EU per vial. For context: the pharmacopoeia allows 5 EU per kilogram of body weight for parenteral preparations, which works out to 400 EU for an 80 kg person. Oils and tablets are deliberately not tested for endotoxins - the assay requires an aqueous sample.

Test us yourself

You win either way

You don't have to take our word for it. For products with no lab report yet, or only an older one, you can commission a test yourself - just agree it with us beforehand. Whatever the result, you get the test cost back as account credit: 100% at Analiza Białek and the Madsen Akademie, 50% at Janoshik.

100% at Analiza and Madsen, 50% at Janoshik

No matter the result, the test cost comes back as account credit - usable on your next orders (not payable out). At Analiza Białek and the Madsen Akademie we credit 100%, at Janoshik 50%. Independent testing helps the whole community, so we carry a large part of it.

Defect? Replacement on top

If the test shows a real defect (wrong compound or clearly too low purity), our replacement guarantee kicks in on top - we make it right.

So we can recognise it:

  1. Agree the test with us first (which product, which lab, which test) - message us on Discord, Telegram or WhatsApp. We'll confirm whether the product qualifies: products with a current report are excluded, since that report already exists.

  2. Our label must be on the vial - that's required. Single vials already come labelled. And with every 10-pack we always include an extra stick-on label, so you can put it on one of the 10 vials and send that one in whenever you want.

  3. On the lab order, always enter thepeptidedesk.org as Manufacturer, your username as Client and the product you bought as Sample.

  4. Once you share the lab analysis, we review it and credit the test cost to your account - 100% for Analiza Białek and the Madsen Akademie, 50% for Janoshik.

Lab results reflect the specific tested sample. We add new analyses as further batches are tested. This information is for research and educational purposes only.
