Peptide tools

Calculators and lookups for reading peptide research and labels

Six free tools for the conversions people get wrong and the comparisons search results do not give you. They do the arithmetic and show the evidence. None of them tells you what to take.

Calculators

Work out the numbers

Arithmetic for vials, volumes and half-lives. Each one shows the working, so you can check it by hand.

Lookups

Look up the evidence

Built on the 52-compound database: evidence grades, legal status and label schedules, side by side.

Start from your question

Which tool answers it

How the tools are built

Four rules every tool follows

Math, not advice

No tool suggests an amount, a schedule or a product. They convert numbers you enter or show what a label or trial reported.

Working shown

Calculators print each step of the arithmetic under the answer, so a wrong input is easy to spot.

Nothing sent anywhere

Calculations run in your browser. The numbers you type are not stored or sent to Staate.

Data with sources

Half-lives, grades and statuses come from the peptide profiles, and every profile cites the study or label behind each value.

Every calculation assumes the vial holds what its label says. How to read a COA covers what testing can confirm.

The Staate peptide brief

Hear when a new tool or a new trial lands

A daily email on peptide research, label changes and FDA actions, with links to every source. No product pitches.

Frequently asked questions
Are these peptide calculators free?
Yes. Every tool on this page is free and needs no account. A free membership adds studied-dose tables on each peptide page, which list the doses used in published trials with their sources.
Do these tools recommend a peptide dose?
No. The calculators only convert the numbers you enter, and the lookup tools show what labels and published trials reported. Staate does not recommend doses, schedules or products, and it does not sell peptides.
What is the difference between the reconstitution calculator and the syringe converter?
The reconstitution calculator starts from the vial: amount of powder and water added. It works out the concentration and how far to fill the syringe. The syringe converter starts from a known concentration and converts any mark on a U-100 or U-40 syringe to mL and micrograms.
Where do the half-lives come from?
Each peptide profile records the half-life reported in human studies or on the approved label, with the citation. The half-life tool only offers the 19 compounds where a human value exists. For the rest, the profile says the half-life is unknown in humans.
Can I trust the label on a research-chemical vial?
Not on its own. Research-use-only products are not made under drug manufacturing rules, so no regulator checks that a vial holds what its label says. Every calculation here assumes the label is accurate. The guide on reading a certificate of analysis explains what testing can and cannot confirm.
