Who is behind this site
Editorial Team
The people responsible for what is published here, what we are qualified to tell you, and what we are not.
Marcus Reinhardt, Editor
Marcus Reinhardt runs Peptide Insider and is responsible for the vendor scoring methodology, the review of laboratory documentation, and final sign-off on everything published on this site. He is the point of contact for corrections and for vendors who want to dispute a finding.
His work here is documentary rather than clinical: reading certificates of analysis, checking that the batch tested is the batch being sold, verifying that the issuing laboratory is named and independent, and tracking published prices so they can be compared on a per-milligram basis.

What we are qualified to say
We are qualified to tell you what a vendor has documented and what they have not. Whether a certificate of analysis exists, whether it matches the batch on sale, whether the laboratory that issued it can be identified and contacted, whether purity and identity were established by recognised methods, and what a product costs per milligram against the rest of the market.
That is a documentary question, and it can be checked by anyone who reads the same paperwork we do. Where our evidence is incomplete, we say so on the page rather than filling the gap with an opinion.
What we are not qualified to say
We do not employ clinical staff, and we do not publish clinical guidance. This site carries no dosing protocols, no treatment recommendations, and no advice on whether any person should use any compound. Those are medical questions, and they belong with a qualified healthcare professional who knows the individual case.
We think stating this plainly is more useful than a vague claim of medical oversight. A reader can then weigh our sourcing and laboratory analysis for what it is, and take health questions to someone equipped to answer them.
The compounds covered on this site are research chemicals. Nothing published here is medical advice, diagnosis, or a treatment recommendation. See our medical disclaimer.
Ownership and funding
Peptide Insider is operated from North Gould Street, Sheridan, Wyoming 82801, United States.
The site does not sell peptides and has no ownership interest in any vendor it covers.
It is funded by affiliate commission: some links to vendors here are affiliate or referral links, and we may earn a commission if you buy after following one. No vendor can pay for placement, for a higher score, or for the removal of a finding, and an affiliate arrangement does not affect how a vendor is scored. The full position is set out in our editorial policy.
How we work
Our evaluation method, scoring, independence, and corrections process are set out in full in the editorial policy.
To report an error or submit documentation, write to contact@peptideinsider.org. Submissions are assessed against the same evidence standard as everything else on the site.
