The elements behind every batch
Every peptide we ship rests on the same four foundations: verified purity, independent testing, proper cold chain, and complete traceability. Below are all the elements that make up our standard.
HPLC purity
Every batch is analyzed using high-performance liquid chromatography. We show purity numerically, without rounding up.
≥ 99% typical
MS identity
Mass spectrometry confirms that the molecular mass is exactly what it should be. No incorrect sequence gets through.
Confirmed mass
COA report
For every batch, you receive a certificate of analysis (COA) with all results. The document is linked to the batch number on your vial.
Included with every shipment
Cold chain
Lyophilized and packed with gel inserts. The temperature stays low from our warehouse to your door across Slovenia and Croatia.
Insulated packaging
Independent testing before every batch release
We send a sample of every new batch to an independent laboratory. We don't produce or edit the results ourselves — we publish exactly what the analysis returns. If a batch doesn't meet the threshold, it doesn't go on sale.
- ✓HPLC chromatogram with a clearly visible main peak
- ✓MS confirmation of molecular mass
- ✓Batch number linked to your vial and COA
From lyophilization to your door without interruption
Peptides are heat-sensitive. That's why we pack every order in insulated packaging with gel inserts and hand it over to express delivery, so the shipment stays cold throughout the entire journey.

What this looks like in practice
From vials and batch labels to analytics — every step is visible and documented.

Every element in its place
How the four foundations come together in a single shipment.
Synthesis and lyophilization
The peptide is synthesized and lyophilized into a stable form, ready for storage.
Independent testing
A sample goes through HPLC and MS analysis. The results become part of the batch's COA report.
Labeling and traceability
Every vial gets a batch number that you can match to its corresponding certificate.
Cold shipping
The shipment is packed with gel inserts and dispatched, so it stays cold until it arrives.
