About this site

Why it exists, how the sources are chosen, and the full disclaimer.

Why we built this

Interest in peptides is exploding, but the information landscape is a mess. On one side you have marketing pages selling miracle cures. On the other side you have dense PubMed papers that require a biochemistry degree to read. In between, there is almost nothing — no place where a curious, intelligent adult can learn what the science actually says, in language they can understand, without someone trying to sell them a vial.

That's the gap Peptides for Dummies fills. We believe people deserve honest, accessible education so they can make informed decisions about their own health — safely and responsibly. We don't sell peptides. We don't recommend you take them. We summarize the research, label every study as human or animal, link to the original papers, and let you draw your own conclusions.

If even one reader walks away better informed — able to spot hype, ask their doctor smarter questions, or simply understand what a peptide is and isn't — this site has done its job.

How we choose sources

We prefer peer-reviewed primary research, especially studies indexed in PubMed. Review articles are used where helpful but labeled as such. For every article we verify the most important citations with live links (PubMed or DOI). For supporting citations, when we cannot find a stable link, we list the authors, year, journal, and title so you can search for the paper yourself.

We do not invent citations. If a study feels uncertain, we drop it rather than guess.

Human vs. animal studies

This is the single most important distinction in peptide research, and most marketing websites hide it. A finding in mice is not a finding in people. A finding in a rat ankle tendon is not a finding in a human tendon. That doesn't make animal research worthless — it's how biology gets figured out — but it does mean you should read it for what it is.

On every blog post you'll see one of three badges on each individual study:

• 🧑 Human — the study enrolled human participants.
• 🐀 Animal — the study was in animals (rats, mice, pigs, etc.) or in cells.
• 🧑🐀 Both — a body of work with both human and animal studies in the same paper or program.

The top of each article has an overall badge summarizing where the research for that peptide mostly lives.

Affiliate disclosure

Some blog posts on this site contain affiliate links to retailers such as Amazon, Bol.com, and iHerb. If you click one of those links and make a purchase, this site may earn a small commission at no extra cost to you. We only list books, research supplies, and related products we would recommend regardless of the affiliate relationship. Affiliate links never influence which studies we cite or how we summarize them — the scientific content is written first, and products are added afterwards.

Disclaimer

The content on Peptides for Dummies is provided for educational and research purposes only. It is not medical advice, diagnosis, or treatment. Nothing here should be interpreted as a recommendation to use, purchase, possess, or administer any peptide. Most peptides discussed on this site are not approved by the FDA, EMA, or other regulators for human use. Where a peptide is approved (for example, semaglutide analogues), that is stated in the relevant article.
