## About Peptide Library

Peptide Library is an independent research hub for peptides. It brings together the reference material, the math and the price data that people researching peptides usually have to piece together from forums, vendor sites and spreadsheets.

Research library. Profiles for more than 200 peptides, each with key facts such as CAS number, molecular weight, half-life, FDA status and the level of evidence behind it, plus its aliases and the pathways it targets.

Reconstitution calculator. Enter the vial size and the amount of bacteriostatic water you add, and the calculator gives the concentration, the volume to draw and the matching units on a U-100 syringe, along with doses per vial. A blend mode works out each compound's concentration when two or more peptides share one vial, and a cost mode turns a vial price into cost per dose and per milligram. Every peptide profile opens the calculator with its typical vial size preloaded.

Vendor price comparison. Prices from public vendor listings are compared per milligram. Each vendor counts once, at the median of its own listings, so a vendor that lists many sizes can't skew the result, and the collection dates are shown next to the prices.

Mobile apps. The iOS and Android apps add dose logging, vial and inventory tracking, schedules and reminders, so a research protocol can be followed day by day.

Who it is for. Researchers, students and anyone reading about peptides who wants reference information, correct math and current prices in one place instead of across a dozen tabs.

Pricing. The library, the calculator and the vendor comparison are free on the web and need no account. Peptide Library Pro ($4.99 a month, $39.99 a year or $89.99 lifetime in the apps) adds unlimited inventory, cloud sync and backup, the blend calculator in the app, courses and community Q&A, data export and progress photos.

Peptide Library does not sell peptides. All content is for research and educational use only and is not medical advice.
