5/5Update-bugs fixed. Was working great, but now there's bugs
Update- reached out to Support and they fixed the app in a matter of days. All of a sudden, when I edited then saved the calculation to a saved protocol, it deleted all the notes that were there previously, which had not occurred in the past. It's also not letting me edit notes in saved protocols.

4/5Great app
Great app for figuring peptide calculations. I love being able to save the calculations especially when you are using multiple peptides. The only drawback is there isn’t a logging function. Having a logging function would be super handy especially if it told you how many days you had left so you could keep up with when to order more. Just something as simple as a start date with the saved calculations an AM or PM box to check.

5/5Beginner Friendly
I recently started using this peptide calculator, and I couldn't be happier with my experience! As a complete beginner, I found it incredibly user-friendly and easy to navigate. The clear instructions and intuitive interface made calculating dosages a breeze. I highly recommend this tool to anyone looking to simplify their peptide measurements. It’s a game-changer for both newbies and seasoned users alike!

5/5I’m not an idiot but calculations for reconstituting confused me at first.
I didn’t quite understand micrograms compared to milligrams, even though I love the metric system and understand it. It took me a minute to figure out that micrograms are the measurements used in the dosing, whereas milligrams is just a general weight or concentration of the medicine. All that to say that by working with this app, it helped to solidify my understanding of it all.

4/5Needs mcg/mg pull-down button!
App is great except that I have to go outside the app to convert milligrams to micrograms. I know that this is a very simple conversion, but I want to be 1000% sure and it would give me peace of mind if I could have the app do the conversion for me. I mean, it already has the tick mark thing, which if you can’t read a scale and figure out how much each tick mark represents, then maybe you have no business injecting yourself.

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
