Evaluating us
Kovagen reviews, and why there are none
Kovagenpublishes no customer reviews, testimonials or star ratings. A review of a research chemical describes someone's experience of using it, and in this category that is a human-use claim made on our behalf — the one thing research-use supply cannot involve. Judge us on the analytical record instead.
Why a review would be a compliance problem
Everything in this catalogue is supplied for laboratory research use only, and is not for human or veterinary consumption. A testimonial describing what a compound did for someone converts that supply into the promotion of an unapproved drug, regardless of what our footer says. It does not matter that a customer wrote it rather than us — publishing it is the act that matters.
This is the same reason the catalogue has no research-area categories, no dosing charts and no before-and-after imagery. The constraint is consistent, and a supplier applying it inconsistently is telling you something.
We also do not publish a rating
There is no aggregate rating in this site's structured data and there will not be. Rating markup without genuine reviews behind it is fabrication, and self-serving review markup violates the structured-data guidelines it would be trying to exploit. A five-star badge on a page like this would be evidence against us, not for us.
What we would rather be judged on
A star rating is an opinion aggregate. A certificate of analysis is a measurement made by a named third party against a specific batch of material, and you can check it yourself. In a category with a documented trust problem, the second is worth more than the first — and unlike the first, it cannot be bought.
Instead of a rating
Seven checks you can run on us
Apply these to us and to anyone we compete with. They are the same checks set out at greater length in how to evaluate a research peptide supplier.
Is testing per lot, or per product?
Purity is a property of a batch. A certificate attached to a product line rather than a lot describes material that may no longer exist. If the same certificate has sat on a page for two years, either no new material was made or it was not tested.
Is the laboratory named, and independent?
An in-house figure is a self-assessment. A third-party result is attributable to someone with no commercial interest in it. A certificate that names no issuing laboratory is attributable to nobody.
Can you retrieve a certificate by lot number, without an account?
Evidence behind a login is not evidence. Every lot here is retrievable by the number on the vial, by anyone, including someone who has never bought from us.
Does the certificate state its methods?
A number without a method is not a result. Look for the method per parameter, the detection wavelength for HPLC purity, and a specification the result was measured against.
Is net peptide content reported?
The parameter most often omitted, and one of the most useful — it is the harder, less flattering number, so reporting it says something.
What does the catalogue claim?
Therapeutic categories, dosing charts, outcome language and testimonials indicate a supplier that treats research-use framing as a formality. That is a judgement they have made, and you can reasonably infer how they make others.
Will they decline to answer something?
A supplier that answers questions about human use will say whatever is asked of it. One that declines, and explains why, is showing you a boundary it holds when holding it is inconvenient.
