How we know what is in the vial — and why you should check
In a market where independent testing keeps finding product at 71–91% of claimed purity, and where some vials contain no active ingredient at all, “trust us” is not an answer. Neither is a certificate, on its own. Here is the actual chain, in order — and then the part that matters more than any of it.
Known input, verified measurement, audited output
- 01
We know what goes in
Every active we use arrives with a certificate of analysis in hand before it is touched. We do not buy on trust and test afterward — we know the identity and purity of the raw material going into the formulation, before it goes in. Actives are purchased directly from established API manufacturers rather than through resellers repackaging someone else’s material, because a certificate is only worth the chain of custody behind it.
- 02
We measure it precisely
Analytical balances verified against certified weights. Positive-displacement dispensing held to a fraction of a percent. Fills confirmed gravimetrically rather than assumed. Known input plus verified measurement means the contents of a finished vial are a calculated quantity, not an estimate — you can arrive at what is in the vial by arithmetic, not by hoping.

We test the output, and we let outsiders check us
We test and COA our own product on a regular basis. Third-party laboratories are used to verify that our procedures produce what our procedures say they produce — not as a substitute for knowing, but as an audit of whether we are right. Testing your own work tells you whether the process held. Having someone else test it tells you whether you were fooling yourself.
We would rather you did not take our word for it
Send our product to a lab. Any lab. Ones we have never heard of.
We actively welcome customers doing their own independent testing on randomly selected vials, and here is why that matters more than anything we could publish: we have no ability to influence it.
A certificate we commissioned tells you what a sample we selected looked like on a day we chose. A test you commissioned, on a vial you picked, tells you what we actually ship. That is the stronger evidence, and it is the only kind we cannot game.
In a market where a vial can contain nothing at all, being the company that asks you to go check is the position worth holding.
The industry's answer to all of this is a certificate showing peptide purity — 99% and change, which looks reassuring. But look at what that number covers: a measurement of the peptide, usually by HPLC, usually on dry powder, usually at one moment in time. The moment it was tested.
It says nothing about the pH of the solution you will actually be injecting, whether the counterion was ever exchanged, what else is in the vial and whether any of it protects anything, or endotoxin unless separately tested. And it says nothing at all about what survives the weeks after the vial is opened — which is exactly why our process is built around what happens after it leaves.
