The standard
Evidence is the product.
Everything below describes what happens to every batch — not what we hope is true of it.
01
Tested per batch, by a third party
Batches are tested by an independent analytical laboratory, not in-house. An in-house purity number is a self-assessment; a third-party result is checkable by someone who does not work for us.
02
A certificate belongs to a batch
When a new batch is released it is tested again, and the certificate published against it is that batch's certificate. We do not carry a previous batch's result forward.
03
Batch-keyed
Each vial carries the batch number that keys its certificate, so what is in your hand can be checked against the analysis for that batch.
04
Ambient dispatch, stated plainly
Shipments travel at ambient temperature — appropriate for lyophilized powder, and said outright rather than dressed up as something colder.
Certificates
Every batch, traceable by its number.
A certificate should name the batch, state what was tested, state the method used, and be traceable to the laboratory that produced it. A purity figure with no batch number and no issuing laboratory is a marketing claim, not a result.
The batch number is printed on the vial label, next to the expiry date.

Common questions
Asked before ordering.
Short answers, each one linked to the full question. Nothing here is a recommendation — the answers describe how material is made, tested and shipped.
What does research use only mean?
It means the material is supplied for laboratory research. It is not a drug, food, dietary supplement, cosmetic or medical device, it is not for human or veterinary consumption, and no claim is made that it treats or prevents anything.
Is Kovagen third-party tested?
Yes. Testing is performed by an independent analytical laboratory rather than in-house, the laboratory is named on the certificate, and every certificate is tied to a specific batch and published openly.
Do you publish certificates of analysis?
Yes. Every batch that has been tested has a certificate published against it, retrievable by the batch number on the vial. The certificate library is open — no account is needed, because evidence behind a login is not evidence.
How should peptides be stored?
Sealed, dry and cold. Keep the vial closed with its desiccant intact, and hold it at the temperature stated on that batch's certificate. Moisture is the variable that matters most, because water enables most degradation pathways.
Why is material shipped at ambient temperature?
Because sealed, desiccated lyophilized powder does not need refrigeration to survive transit. Shipments are not temperature-controlled and do not travel on ice, which is appropriate for the form rather than a compromise.
Are Kovagen peptides made in the USA?
Yes. Material is manufactured in the United States, held sealed and desiccated through to dispatch, and shipped domestically. Testing is carried out by an independent analytical laboratory.
