Who writes and reviews content here?
Articles on The Pep Expert are written by a senior staff writer with a background in science communication. Each article is then reviewed by a qualified medical reviewer before it goes live. The reviewer's name, credentials, and review date appear on every article they sign off on.
The medical reviewer checks factual claims against primary sources, flags unsupported assertions, confirms that evidence tiers are labeled correctly, and verifies that no article makes disease-treatment claims or implies that a research compound is approved for clinical use. The writer and reviewer operate independently of each other's drafts until the review stage.
Neither the writer nor the reviewer accepts payment, free products, affiliate commissions, or any other compensation from peptide vendors, supplement companies, or compounding pharmacies. Editorial decisions are made without input from commercial partners.
How evidence is graded and sourced
The Pep Expert uses four evidence tiers, and every article labels them explicitly so readers know what kind of support exists for any given claim.
Tier 1 is human randomized controlled trials (RCTs). These are the highest standard of evidence and are noted as such. Tier 2 is small or uncontrolled human studies, including open-label trials, case series, and observational data. These are described plainly as preliminary human evidence. Tier 3 is animal studies, typically rodent models. These are labeled as preclinical and noted as not yet replicated in humans. Tier 4 is in-vitro research, meaning cell or tissue studies conducted outside a living organism. These are the earliest stage of evidence and are described that way.
Most peptide research currently sits at Tier 3 or Tier 4. When that's the case, articles say so directly. Readers should not interpret preclinical findings as proof of human benefit.
Sources are drawn from peer-reviewed journals indexed on PubMed (pubmed.ncbi.nlm.nih.gov), registered trials on ClinicalTrials.gov, and official regulatory documents from the U.S. Food and Drug Administration (fda.gov). Writers do not cite press releases, vendor websites, or secondary summaries when a primary source is available. Every URL in a published article is verified before publication.
- Tier 1: Human RCT, highest evidence standard
- Tier 2: Small or uncontrolled human study, preliminary
- Tier 3: Animal study, preclinical, not yet replicated in humans
- Tier 4: In-vitro study, earliest stage of evidence
What this site does and does not claim
All content on The Pep Expert is educational and informational. Nothing published here constitutes medical advice, a treatment recommendation, or a protocol for using any compound. Readers should consult a licensed healthcare provider before making any decision about their health.
Several compounds discussed on this site have FDA-approved pharmaceutical forms. When that's the case, articles name the specific approved brand and note that research-chemical versions sold outside that approval pathway are not approved for human use. Compounds without any approved form are identified as research chemicals throughout.
This site does not present dose figures as recommendations of any kind. Dose figures appear only when reporting what participants in a specific published study received, and they are attributed to that study by name, year, and journal. No article on this site uses language that implies a compound has been proven to work or has cleared any regulatory bar it has not cleared.
How corrections are handled
If a factual error is identified after publication, the article is updated and a correction note is added at the top of the page. The note states what was changed and when. Minor edits for clarity that do not affect factual content are made without a correction notice.
Readers who spot a potential error can contact the editorial team through the site's contact page. The medical reviewer evaluates flagged claims and determines whether a correction is warranted. There is no set timeline for corrections, but the goal is to resolve substantive errors within five business days of identification.
Frequently asked questions
Is the content on The Pep Expert medical advice?
No. Everything published here is educational and informational. It is not a substitute for advice from a licensed healthcare provider, and it should not be used to make decisions about taking, injecting, or otherwise using any compound.
Are the peptides discussed on this site approved by the FDA?
Some compounds have FDA-approved pharmaceutical forms, and articles name those specific approved products when relevant. Many other compounds discussed here are research chemicals with no FDA approval for human use. Articles identify each compound's regulatory status clearly.
Does The Pep Expert have commercial relationships with peptide vendors?
No. The Pep Expert does not accept payment, free products, or affiliate commissions from peptide vendors, supplement companies, or compounding pharmacies. No commercial partner has any influence over what gets published or how compounds are described.
