Tools

Laboratory tools

Free calculators, data pages and games for research peptides. Each calculator opens on a worked example you can change.

Calculators

Calculators

The general tools. Each one has per-compound and per-size pages listed further down.

Reconstitution calculator

Concentration, volume to draw and syringe units for a vial and a target amount.

Syringe units converter

Convert U-100 syringe units, millilitres and micrograms at one concentration, with a printable chart.

BAC water calculator

How much bacteriostatic water gives the concentration you want, for each vial size.

Vial planner

Vials needed for a total amount of material and the material left over for each vial size.

Cost calculator

Cost per mg and per aliquot, from the amount you enter or the Pepcore catalogue figure for that size.

Half-life calculator

Time to 50%, 25% and 10% remaining from a half-life, drawn as a decay curve.

Molecular weight calculator

Convert mg to nmol for a compound from its stored molecular weight.

Blend calculator

Amount of each component in a multi-compound vial at the concentration you choose.

Storage timer

Enter a start date and a window in days for the end date and days remaining.

Vial label maker

Print a vial label with concentration, dates, a lot or COA reference and a QR code.

Dosage calculator

Enter an amount or pick a cited one, then see units per draw, doses per vial and doses per week for a vial size.

Cycle calculator

Total material for a cycle, the vials needed for each size and the cost at Pepcore catalogue prices.

Titration calculator

Build a stepped schedule from your own amounts and see the syringe units for each step.

Per compound

Calculators for a specific compound or vial size

Each link opens the calculator with that compound and vial size filled in.

Data

Data and lookups

Reference data you can sort, search and check.

Master chart

Every compound with category, molecular weight, sequence length, vial sizes and COA status. Sort, filter and download as CSV.

Peptide explorer

Browse compounds grouped by category and see how they connect through categories and blends.

COA library

Find a certificate of analysis by lot number or report ID.

COA checker

Type or paste what a certificate shows and see which fields are missing or need a second look. Pasted text stays in your browser.

Games

Games

Two free games built on the compound data and on how lab reports are read.

All games

Peptide Daily

One research compound a day. Guess it in six tries from five clues.

COA Detective

Flag what is missing or inconsistent on a fictional certificate of analysis.
