Free Sample Testing
Send in samples for free testing
Hold a vial you can't quite vouch for?
Send it to the house. We will have it analysed at an accredited commercial laboratory at no cost to you, and enter the result into the public ledger — for your peace of mind, and for the benefit of every buyer who comes after you.
How it works
Register the sample first, so we can match your vial to your submission on arrival.
Ship the vial to our Austin, TX intake, packed snugly in a padded envelope — a single vial travels well with a little wadding around it.
We log it, code it blind, and submit it to the laboratory. The sample is consumed in analysis, so we cannot return it.
No vial to spare? You can still help: suggest a product or vendor for an upcoming procurement round on Reddit instead.
What you get
You receive a full copy of the Certificate of Analysis — identity, purity, content against the label, and the safety panel — before it is published here on the Medutest site.
Typical turnaround is two to four weeks from arrival, depending on the assay queue and the panel required.
What we test
Medutest accepts 15 popular peptides free of charge, in lyophilised powder form only. For a modest fee we now test many more peptides and blends, and several other form factors:
- Tablets and capsules
- Sprays, liquids and gels
- Raw powder
There is one thing we cannot test:
- Reconstituted peptides — once a vial is mixed, the analysis is no longer reliable, so please send it dry
We currently accept shipments from within the USA only. 🇺🇸
Why it's free
Independent data is only useful if there is enough of it, and kept current. Community samples are the lifeblood of the ledger: each vial one person sends in protects the next person reading it. Funding the analysis ourselves is how we keep the record honest and unbought.
