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, and puts them in one place on the web and in apps for iOS and Android.
Research library. The library has profiles for more than 200 peptides. Each profile lists key facts such as CAS number, molecular weight, half-life, FDA status and the level of evidence behind it, along with the names the compound is also known as and the pathways it targets. Profiles are written for research and education: they summarize what has been published rather than telling anyone what to take, and they mark clearly where human data is missing.
Reconstitution calculator. Reconstitution math is where most mistakes happen, so the calculator walks through it step by step. Enter the vial size and the amount of bacteriostatic water you add, and it gives the concentration, the volume to draw and the matching units on a U-100 syringe, along with how many doses one vial holds. 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 the cost per dose and per milligram. Every peptide profile opens the calculator with that compound's typical vial size already filled in.
Vendor price comparison. Peptide Library compares prices from public vendor listings per milligram, so vials of different sizes can be compared directly. Each vendor counts once, at the median of its own listings, so a vendor that lists many sizes cannot skew the result, and the collection dates are shown next to every price so you know how current a figure is. Vendor pages also collect customer reviews. Peptide Library does not sell peptides itself and is not paid to rank vendors.
Tracking in the apps. The iOS and Android apps add day-to-day tracking for a research protocol: dose logging, vial and inventory tracking, schedules and reminders, so a protocol can be followed and reviewed over weeks instead of from memory.
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 a dozen browser tabs.
Pricing. The library, the calculator and the vendor comparison are free on the web and need no account. Peptide Library Pro is $4.99 a month, $39.99 a year or $89.99 lifetime in the apps, and adds unlimited inventory, cloud sync and backup, the blend calculator in the app, courses and community Q&A, data export and progress photos.
