Synthesised in facilities we have audited, re-tested in Rotterdam by a laboratory with no stake in the result, and delivered cold with the certificate already in the box.
Free delivery over $250 · Certificate with every batch · For research use only
Grouped by the kind of research it gets used in, not by clever marketing names.
Current batches, current purity figures. Prices are per vial and include the certificate.
A supplier is only as good as the batch it is willing to turn away. We fail material at 98.4% because our floor is 98.5% and we do not round up. Here is what each check is actually looking for.
This is the real trace from a real batch, not a picture of one. The tall peak is your peptide. Anything else is what we are trying to keep out. Pick a compound and see for yourself.
It is not a theme. It is a description of how the supply chain actually works.
Almost all of the world's research peptides are synthesised in Asia. That is not a corner being cut, it is simply where the capability and the chemists are. Suppliers who imply otherwise are usually reselling the same vials with a bigger markup.
We work with two facilities, we have visited both, and we keep the batch records rather than just the invoice.
What tends to be missing is not the chemistry. It is the second opinion. So every batch is re-tested when it lands in Rotterdam by a lab that has no relationship with the manufacturer.
Their number is the one we print. It is filed against the batch code, so you can pull it up again in two years when someone asks which material you used.
An account is not a loyalty scheme. It is the record of which batch you actually received, held for as long as you might need to cite it.
