No menu, no reset button. Very user unfriendly. To change an amount, you have to go back and delete the inputted boxes, then type the new number. The issue is that in doing it this way, it keeps the error window up (because all fields must be filled out) and won't show the info for that box (such as how many syringes of water to draw) because the "error" is in that box.

Hi Robin, we apologize for the inconvenience. Please get in touch with hello@isjustawesome.com with a screenshot or recording of your issue. Unfortunately, we functionally can only calculate and show the amount to draw once all inputs are finished, but the inputs should not be covered when you're typing. We'll work with you to get it fixed. Thanks!

Great calculator. The best I've seen. One feature I would like to see is that the notes section be drop down. I like to carry dosage information and benefits information which can be quite long If there isn't a drop down I have to scroll through the whole text to get to different peptides listed.

Excellent. I've checked it against many other calculators and simply doing math myself. It's very accurate. Saw a review saying it wasn't, but he's dead wrong. I like that it shows the number of doses you'd have per vial. Useful info when doing research.
