The "Unlimited & Customizable" update is here! We've listened to your feedback and completely overhauled PepCalc to make it the most powerful and flexible peptide research tool available. What's New: • UNLIMITED MIXES: You are no longer limited to one or two peptides. Mix as many peptides as your research requires in a single volume. • CUSTOM NAMING: Say goodbye to "Peptide 1" and "Peptide 2." Give every peptide in your mix a custom name for perfect clarity. • EXPANDED SCALE OPTIONS: We've simplified the unit picker with all standard 100-unit and 40-unit types, plus the ability to define your own non-standard custom scale types. • 10x EASIER PROTOCOLS: The "Save Protocol" flow has been entirely rebuilt. It is now faster than ever to add, update, or rename your favorite calculations. • FULL-SCREEN RICH NOTES: Protocol notes are no longer confined to a tiny box. Enjoy a full-screen interface with bold, italic, and underline formatting, plus an increased limit of 1,000 characters. • AUTOMATIC UNIT CONVERSION: Switch between mcg, mg, and g in real time with our improved calculation engine. • "UNDO" FUNCTIONALITY: Made a mistake? You now have a 7-second window to undo major actions, like clearing data or opening a saved protocol, via a simple in-app notification. • WATER SOLVER: PepCalc can now solve backwards from your desired amount to calculate how much water to add. • THEMES GALORE: Express yourself with 5 new color schemes, each featuring native Light and Dark mode support that adapts to your device settings automatically. • GLOBAL COMPATIBILITY: All inputs now seamlessly accept both commas and periods as decimal separators for our researchers worldwide.

Minor display tweaks and performance improvements

Bug fixes and performance updates

Multi-peptide Support • Our most requested feature! Optionally add additional peptides to a vial and PepCalc will calculate and display the other amounts per dose. Doses in Vial • We now calculate and display the number of doses available in the vial. Better Multi-dose Information The number of syringes needed will show if the desired dose is greater than 1 full syringe. Dark/Light Modes • Go to Info > Settings and choose Dark, Light, or Operating System color mode. Squashed all the Bugs • Fonts now scale correctly based on the text zoom level on your device. • PepCalc looks great on all phone and tablet sizes.

PepCalc is the easiest way to calculate accurate peptide doses. This release adds several features based on user feedback. • Syringe type selection. To facilitate easier calculation you can now choose between U100 and U40 insulin syringes and then select a Unit count. PepCalc will automatically set the correct volume. No worries if you have a non-insulin syringe. You can pick tuberculin (non-insulin) from the dropdown to get complete control of the inputs. • PepCalc has a memory! A common request we are excited to deliver - PepCalc now remembers the last values you entered. No more unnecessary retyping! • Input bugs squashed. You can now enter numbers with or without leading zeros, i.e., .0 or 0.1
