How we source, grade, and disclose.

Immortal Peps is committed to publishing accurate, transparent, and independent research education. These standards govern every compound guide, research article, and protocol breakdown on the site.

Evidence grading

Every compound guide on Immortal Peps carries an evidence badge that communicates the current strength of available research. The grade is visible at the top of the article and inside the compound card on the library page.

Preclinical — Research is limited to in vitro (cell culture) and/or in vivo (animal model) studies. No peer-reviewed human clinical trials have been published. This is the most common grading for research peptides.
Human Trials — At least one peer-reviewed clinical trial involving human subjects has been published. This does not imply regulatory approval or clinical recommendation — only that human data exists in the literature.
Mixed — Available research includes both preclinical and early-stage human data, but evidence is inconsistent, limited in scope, or conflicting across studies.

Evidence grades are reviewed and updated as new research is published. The grade reflects the state of the literature, not our opinion on the compound’s efficacy.

Source standards

All factual claims must be supported by published, peer-reviewed research. We adhere to the following:

Primary sources are peer-reviewed journal articles indexed in PubMed, Google Scholar, or equivalent academic databases.
We do not cite manufacturer data sheets, promotional materials, blog posts, forums, or social media as evidence.
Review articles may be cited for context, but the underlying primary studies are linked where possible.
Preprint studies (not yet peer-reviewed) may be referenced but are clearly labelled as such.
All references are linked directly in the article body and compiled in a References section at the end of each guide.

Writing principles

Our editorial style is built around four commitments:

Clarity over jargon. We translate the science, but we don’t strip the meaning. Key terms are defined in-line.
Honesty about limits. If a study was in mice, we say mice. If a sample size was twelve, we say twelve.
No therapeutic claims. We do not state that a compound “treats,” “cures,” or “prevents” any condition in humans unless a regulatory body has explicitly approved that indication.
No dosing recommendations. Compounds discussed on this site are not approved for human use outside limited, specific indications. We do not provide protocols.

Disclosures and conflicts

Immortal Peps is an independent education platform. We do not sell compounds, accept sponsorship for coverage, or accept payment to influence rankings or sequencing.

Where any commercial or affiliate relationship exists, it is disclosed in plain language on the affected page. We do not link to compound suppliers from research articles. If a research article references a commercial source for educational context only, the link is marked with rel="nofollow sponsored".

Updates and corrections

Research evolves. When a study we cited is retracted, when a new Phase 3 trial changes the evidence picture, or when we identify an error in our own copy, we update the article. Material corrections are timestamped at the bottom of the page.

Reader feedback

If you’ve spotted an error, an out-of-date claim, or an unsupported statement, we want to hear about it. Contact the editorial team via the form on our contact page. Substantive corrections are credited unless the reporter requests otherwise.

What this site is not

Immortal Peps is not:

A medical or clinical reference.
A recommendation service.
A retailer or supplier of any compound discussed.
A substitute for licensed medical advice.

Compounds discussed are not approved for human consumption outside specific indications granted by regulatory authorities (FDA, EMA, MHRA, etc.). Any human use outside those indications is at the reader’s own risk and is not endorsed by Immortal Peps.
