About PeptideTDB
PeptideTDB is the Peptide Transparency Database. Plain-language summaries of the scientific studies on peptides: what was tested, what it found, what it cannot show, and who paid for it.
Who runs it, and who pays
This site is run by an employee of Pürblack, a peptide supplement brand, in a personal capacity. Pürblack does not fund, review or direct the site, and its costs are paid by its operator.
That connection matters when you read anything here that touches a supplement brand, so it is stated openly, on every page footer and wherever a Pürblack product is named.
What this site does
- Summarises peer-reviewed studies on peptides (12 so far), saying what each found, what it cannot show, and who funded it.
- Rates the evidence for each use on a topic page, with the date the rating was last reviewed.
- Explains peptide terms and the legal and regulatory picture, with sources and dates.
- Publishes its study registry as a free download.
What it does not do
- It does not give medical or legal advice or recommend that you use any peptide.
- It does not sell products.
- It does not currently grade or rank any products.

Educational information only. It is not medical or legal advice, and nothing here is a recommendation to use any peptide. Talk to a clinician before starting a supplement or treatment. Last reviewed November 9, 2026.
