About Canine Peptide Guide

Search for almost any peptide alongside the word "dog" and you will find two kinds of page: a supplier describing a compound in glowing terms, or a forum thread where someone is guessing. Neither tells you what has actually been studied, in what species, at what dose, or what could go badly wrong.

This site exists to be the third kind of page. It covers 9 compounds investigated in dogs, cites 32 peer-reviewed studies, and marks the 6 that were conducted in dogs rather than extrapolated from rodents or people — because that distinction is the most important and most frequently obscured fact in this field.

Who this is for

Dog owners researching a specific problem, and veterinary professionals who want the primary literature collected in one place rather than scattered across PubMed. The writing tries to serve both: plain-language mechanism first, clinical detail alongside, sources at the bottom of every page.

What we deliberately do not do

• Sell anything. No products, no cart, no checkout. Our commercial relationship is a disclosed sponsorship, described in full in the editorial policy.
• Overstate the evidence. Several compounds here are graded preliminary, and one — PNC-27 — has no companion animal data whatsoever. We say so on the page rather than in a footnote.
• Replace your veterinarian. Several compounds require screening that only a veterinarian can order and interpret: MDR1 genetic testing before ivermectin, cancer screening before TB-500, liver values before injectable GHK-Cu. A website cannot do any of that.

How to use this site

If you know the compound, start at the compound index. If you know the problem, start at conditions. If you want to check whether something is appropriate for your dog at all, start at safety — it collects the contraindications and breed genetic risks in one place, which is the right first stop more often than people assume.

Corrections

If something here is wrong, we want to fix it. A misread study or a dosing figure that does not match its source is a real problem on a site people use to make decisions about their animals.
