What we will not send you

Anyone can publish a good number. The more useful question is what a supplier does on the day the number comes back wrong. This page is our answer, written down so you can hold us to it.

The process

Four checks, and nothing skips one

In plain English first, with the technical name underneath in case you want to look it up.

Why we pay for a second opinion

A manufacturer's certificate is written by the one party with the strongest reason for it to pass. That is not dishonesty. It is just how the incentive sits.

Re-testing costs us roughly four per cent of our margin and adds nine days to lead time. We wear both, because the alternative is you finding a two per cent impurity halfway through a study with no way of knowing whether it came from our vial or your bench.

What we checkWhat we insist on
How pure it is98.5% or better
That it is the right moleculeWithin 0.5 of the expected weight
Bacterial residueBelow 0.5 EU/mg
How much water it holdsBelow 6.0%
Leftover solventReported, not capped
How it looksOff-white, loose, free-flowing
Delivery

Keeping it cold is not a sticker on the box

Peptides do not enjoy warmth. Here is what actually happens between our fridge and yours.

1

Proper packaging

A vacuum-panel shipper with a 4 °C phase-change pack, not a gel block. It holds temperature for 96 hours in a 30 °C summer, which covers most of the journey from Singapore to anywhere.

Packing
2

A logger in every box

The temperature logger travels inside with the vials rather than taped to the outside, so it records what your material felt, not what the cardboard felt.

Monitoring
3

We call you first

If the readout breaches specification we send the replacement on reading the log. Most of the time you will hear from us before you have opened the first box.

If it goes wrong
4

Two places to ship from

Singapore for Asia-Pacific, Rotterdam for Europe and the UK. Regional stock means less time in transit and fewer customs stops.

Where it comes from

If something is wrong

Written plainly, because policies that need a lawyer are usually hiding something.

If it is our fault, we replace it

Purity below specification, failed identity, a warm shipment, a cracked vial, the wrong item. Tell us within thirty days and a replacement goes out at our cost.

You do not need to send a compromised vial back, and there is no restocking fee. A photograph of the vial and the logger readout speeds it up, but it is not a condition.

If it is not, we will say so

Once material has been reconstituted, decanted, stored outside its stated conditions or sent on to somebody else, we can no longer stand behind the certificate attached to it, so we cannot replace it.

Unopened material that has been stored properly can come back within fourteen days for a refund, less carriage.

Who we sell to, and what this is

Everything here is a laboratory reference chemical. None of it is a medicine.

We do not publish dosing information, administration guidance or health claims, and we will not supply them if you ask. That is not us being awkward. It is the line between a research supplier and an unlicensed pharmacy, and staying on the right side of it is the whole business.

If you want to know what a compound is, how pure it is, or how to store it, ask away and we will tell you gladly.
