About the Peptide Therapy Index

What this site is

The Peptide Therapy Index is an independent catalogue of clinical and preclinical research on peptide therapies. It is not a product review site, a supplement retailer, or a medical advice service. It is an index — a structured collection of primary-source research, assessed for study type and presented for researchers, clinicians, and informed lay readers who want to understand what the evidence actually shows.

Each article addresses a specific research question. The answer reflects the current state of the published evidence, not the prevailing assumptions of the peptide community. Where evidence is preliminary, that is stated. Where no controlled human data exists, that is stated. Where findings have not been independently replicated, that is stated.

Editorial standards

Every post on this index is categorised by study type before anything else is said about it. The four categories — RCT Evidence, Preclinical, Case Series, and Review / Meta — are not interchangeable. Preclinical findings in rodents are informative but cannot substitute for human trial data. Case series establish clinical plausibility but cannot control for natural recovery or placebo effect. This distinction is the foundation of every editorial decision made here.

Primary sources take precedence over secondary commentary. Where a finding is described, the study it originates from is the relevant evidence — not the forum post, the podcast, or the influencer summary of that study. Citations link to original research wherever possible.

Uncertainty is acknowledged explicitly and precisely. The phrase "the evidence here is preliminary" means something specific: the findings exist but have not yet been tested in controlled human trials. The phrase "no human data exists" means the only evidence is from animal models or cell culture. These distinctions are preserved in every article.

No commercial interest

This site sells nothing. There are no affiliate links to peptide suppliers, compounding pharmacies, or any other commercial entity. There is no advertising. No content is sponsored. No payment influences editorial decisions in any direction.

The Peptide Therapy Index exists because the peptide research space has a large information quality problem: the same findings are frequently overstated, misrepresented, or repeated without acknowledgment of their evidentiary limitations. An independent index applying consistent editorial standards is a practical response to that problem.

What this site is not

This site does not provide medical advice and is not a substitute for clinical consultation. No content here should be used as the basis for a treatment decision without the involvement of a qualified healthcare professional who can assess individual circumstances. The research presented here is descriptive — it describes what studies found. It does not prescribe.
