How we decide what to tell you
Pepperz is an independent reference for peptides: 176 compound profiles, 117 glossary terms, 15 guides, and four free tools. This page explains how that content is produced, and — just as importantly — what it is not.
The most important thing on this page
Our content is not medically reviewed.
No licensed clinician writes, reviews, or approves what you read here, and we will not pretend otherwise by adding a reviewer’s name to a page they never read. Pepperz does not provide medical advice, diagnosis, treatment, prescribing guidance, or dosing recommendations. Nothing here is a substitute for a conversation with a qualified healthcare professional who knows your history.
This shapes what we write about. We cover what the regulations say, how the chemistry and arithmetic work, how to judge a source, and what the published evidence does and does not show. We deliberately do not answer questions whose honest answer is “ask your doctor”.
What we promise
We cite primary documents, not other blogs
Regulatory claims are traced to the FDA page that makes them, drug labelling to DailyMed, and research to PubMed or the trial registry. When we found that the widely repeated claim “the FDA removed BPC-157 from Category 2” meant something quite different from what was being reported, we found it by reading FDA’s own table instead of the coverage of it.
Every link is checked before we publish
A citation that does not resolve is not a citation. Each external URL on this site is requested and confirmed to return a real page before the content ships. Fabricated or hallucinated references — including plausible-looking PubMed IDs that lead nowhere — are the single fastest way to lose a reader who checks, and the readers we want are the ones who check.
We sell nothing, and we take no vendor money
Pepperz does not sell peptides, does not accept payment or product from vendors, does not run affiliate links, and does not rank or endorse suppliers. Almost every peptide guide that ranks in search is published by a company selling peptides. That conflict shapes what those guides can say. Ours has no such constraint, which is the only reason we can tell you that a product’s evidence is thin.
We grade evidence honestly, including “unknown”
Preclinical is not clinical, a rodent study is not a human result, and a plausible mechanism is a reason to run a trial rather than a substitute for having run one. Where the honest summary of a compound is “unknown in humans”, we write that, even when it is the least satisfying sentence on the page.
We separate the regulatory question from the safety question
“Legal” and “safe” are different claims, and conflating them misleads in both directions. A withdrawn FDA nomination does not make a substance safe. An approved drug can still be counterfeited. We try to answer whichever question you actually asked.
We correct things, in public
Each guide carries the date it was last updated, and regulatory guides additionally carry the date the sources were last verified against the primary documents. Regulation moves. If a page is old, treat the date as part of the content, and follow the source link.
Who writes this
Guides are published under the byline Pepperz Editorial. We use an organisational byline rather than inventing individual expert authors. If we engage clinical reviewers in future, we will name them, state their credentials, and show the date they reviewed each page — and not before.
Compound profiles combine a structured catalog with hand-written editorial sections and real citations. Evidence levels reflect the strength of the underlying research, not the enthusiasm of the internet.
Found something wrong?
Tell us and we will fix it. Errors of fact, dead citations, and regulatory changes are all worth reporting — a correction costs us nothing and a wrong page costs a reader something real. Every compound profile also carries a “Request update” button that goes straight to us.
