As of: Aug 26, 2026 · Where these numbers come from
Name or contact
You have a name, a shop link, a Telegram contact or an email. Enter it and see what we know about this supplier - and what we do not.
What you type is not stored, and it never shows up again.
A contact path you enter is never published by us.
We also know 3,489 further suppliers by name without a clear evidence base. You can still look each of them up via search.
Dimensions

No. This is not a normal online purchase.
No buyer protection, no company with an address, no right of withdrawal. You pay someone you don't know - and the goods travel from China, from manufacturers you don't know.
If that confuses you, it's the market's fault, not yours.
The second question
And what is known about the peptide itself?
A clean contact still says nothing about whether the substance does what it promises. That is why every peptide here gets an evidence score from 1 to 4 - from thin data to full approval. It does not say whether a peptide is good, but how solid the publicly verifiable evidence base really is.

More than the map
Research further
Three ways to go deeper: the documented knowledge, the tools to apply it, and the method it all rests on.
Documented peptide profiles with an evidence score, guides and background - the place for the technical picture.
Injection calculator and reverse dose calculator: mix cleanly, dose correctly, work back to the concentration.
How the evidence comes about, what it rests on and where the limits are.
From the founder
Welcome
Glad you’re here. I’m Samuel - a family man and IT entrepreneur who knows the personal battle with weight, and who got scammed while searching for answers. That’s how Peptigraph was born: a place that protects and informs instead of selling.
