Why PeptideDecoded Exists
Most peptide information online has one goal: sell you something.
PeptideDecoded was created to make peptide research understandable, evidence-based, and free from vendor bias.
We don't sell peptides. We don't earn affiliate commissions. We don't accept sponsored content or vendor partnerships.
We exist because the gap between what the research actually says and what peptide websites claim is enormous — and someone needs to bridge it honestly.
Our Mission
We translate complex peptide research into practical, readable guides backed by peer-reviewed studies.
Every article on PeptideDecoded is built from published literature, written in plain English, and reviewed against current scientific evidence.
We help readers understand what the science says — not what vendors want you to believe.
What Makes Us Different
No peptide sales
We don't sell any products. No peptides, no supplements, no clinic memberships.
No affiliate commissions
We earn nothing if you buy anything anywhere. No vendor referrals, no kickbacks.
No sponsored rankings
No brand has paid to appear on this site — rankings reflect evidence, not sponsorship.
Research first
Every guide starts with published literature — not vendor claims or anecdotal testimonials.
Every claim backed by citations
We link to PubMed and peer-reviewed sources throughout. You can verify every claim yourself.
Author & Editorial Team
PeptideDecoded is run by an independent editorial team led by the site's founder and research lead.
The editorial team works directly from primary sources: PubMed-indexed peer-reviewed trials, FDA press releases, warning letters and import alerts, the WADA Prohibited List, package inserts and regulatory docket filings, and published systematic reviews. Every citation is sourced — no vendor claims, no AI-generated filler, no anecdote treated as evidence.
The site is reviewed and updated continually as new evidence publishes. When a peptide's tier assignment shifts because a new RCT, regulatory action, or systematic review changes the picture, the change is noted in the article and the page's lastmod updates.
How we source, rank, and update content is documented on the editorial-standards page. Read How we rate evidence, the rubric that drives every evidence-tier badge.
Who This Site Is For
For Researchers
A curated, citation-linked index of peptide literature with clear separation of animal vs. human evidence. A fast way to find the highest-tier studies on a given peptide without wading through vendor pages, AI-generated filler, or studies cited in name only.
For Practitioners
An evidence-graded summary of each peptide's status, with regulatory framing — FDA-approved vs. 503A/503B compounding vs. research-only — and an honest accounting of what the literature does and does not support. Useful for patient conversations, not for prescribing decisions.
For Buyers
A vendor-independent way to evaluate peptide claims before spending money. What to look for on a Certificate of Analysis, red flags in marketing language, and honest verdicts on which products have real evidence behind them — and which are selling a rodent study as a human result.
Editorial Standards
Where our studies come from
We source from PubMed, peer-reviewed journals, and systematic reviews. We prioritize human clinical data and clearly label when evidence comes from animal or cell studies only.
How we evaluate evidence
We use an evidence hierarchy — every major claim on PeptideDecoded is labeled with the applicable tier:
| Tier | Source Type | What It Means |
|---|---|---|
| 1 — Gold Standard | Systematic reviews & meta-analyses | Synthesizes multiple RCTs. Highest reliability. |
| 2 — Strong | Randomized Controlled Trials (RCTs) | Controlled human studies with appropriate sample sizes. |
| 3 — Moderate | Observational & cohort studies | Human subjects, lower weight than RCTs. |
| 4 — Supporting | Animal & in-vitro studies | Preclinical only. Labeled explicitly — never extrapolated to human efficacy. |
| 5 — Context | Expert consensus, FDA documents | Used to frame regulatory status and mechanisms. |
Animal vs. human studies
We clearly separate animal evidence from human evidence throughout every article. A promising result in rats does not mean the same outcome in humans. We do not extrapolate animal data to clinical efficacy for people.
If the headline is "BPC-157 shows promise in rodents" but the article never says "there are zero human clinical trials" — that's not an evidence-first resource. That's advocacy. PeptideDecoded names the gap.
The full four-criterion rubric we grade every peptide against lives on /research/methodology.
How articles are updated
We review published research for any article covering an active research area. When new evidence changes the picture, we update the article and note the revision date.
What we don't cover
We do not provide dosing protocols, injection guidance, vendor recommendations, or treatment advice. That is intentional — not an oversight. Peptide therapy decisions belong between you and a qualified healthcare provider.
The content on PeptideDecoded is for educational and informational purposes only. It is not medical advice and should not be treated as such.
We do not recommend or endorse any specific peptide, product, compound, vendor, protocol, or treatment. Nothing on this site should be used to diagnose, treat, cure, or prevent any condition.
Peptide compounds discussed on this site include experimental substances that are not approved by the FDA for human use. Many are legal only for research purposes.
Always consult a qualified healthcare provider before making any decisions about your health.
