PeptidesCalculator.com is a free calculator and reference for people working with research peptides. It does the reconstitution and dose math, and it collects what published studies say about each compound in one place.
Who we are
We build and maintain the calculator, the compound library and the research guides. The information on the site is organized from published studies and regulatory sources. We do not run studies ourselves.
We are not a manufacturer, a distributor or a medical service. The site is a reference, not advice.
What we do
Peptide calculator
Enter the vial strength, the water you add and the dose you want, and the calculator gives the syringe units or pen clicks to draw. It checks that the draw fits the device and warns when a number looks off.
Compound library and guides
Each compound page summarizes what is known, what kind of evidence it rests on (human, animal or lab) and which amounts appear in the sources. The guides cover the basics: what peptides are, how the calculator math works and how to read a study.
Free workspace
A free account saves your calculations so you can reopen them later on any device.
How we work
Sources
Content comes from published studies and regulatory documents. We label the study type so a result in cells or mice is not mistaken for a proven outcome in people.
Accuracy
The calculator math is tested, and every result shows its working so you can check it yourself.
Plain language
We explain terms where they appear and keep pages short.
Limits
Nothing on this site is medical advice. Talk to a qualified professional before acting on anything you read here.
Why the site exists
Peptide dosing math is easy to get wrong, and the information online is scattered and often unreliable. We wanted one place where the arithmetic is right and the evidence is labeled honestly.
A word of caution
The site is educational. We check our sources, but we cannot verify your vial, your protocol or your situation. Confirm everything with a licensed professional before acting on it.
