About this app

Research peptides are taking the world by storm, but calculating proper dosages has always involved manual math calculations and the chance of making potentially dangerous mistakes.

The Peptides App is designed to safely and reliably calculate accurate dosages of reconstituted peptides as quickly as possible—often in as little as 5 seconds or less!

Open the no-nonsense interface and fill in the inputs to see your result straight away, visualized at the top of the screen in a clear, easy-to-read graphic.

Making a common calculation?

Use the “quick entry” buttons below each input to fill in values in the blink of an eye.

And depending on the size of the syringe you’re using, you can select from any one of 3 common volumes—0.3 ml, 0.5 ml, or 1 ml—for the most accurate visualization possible.

Best of all:

You don’t need to create an account (or even have internet access) to use the app; your data is never shared with third parties; and the calculator is (and will always be) 100% free, with development funded by premium learning materials I plan to publish in the future.

Enjoy!

Will not allow decimal point when calculating BAC water. Does not make any sense when you can't use a simple decimal point. App is useless for my needs. Until that has changed, my review stands. If it weren't for that, this app would be a solid 5 star.

Thanks, Ernest! Adding decimal support to amounts is something I'd like to make happen soon—I agree it's a must-have for certain calculations.

Nice app. While support for fractional volume would be nice, no other peptide calculator in the Playstore has it. Besides, not adjusting for say, .5ml of Bac Water shouldnt matter, just round up/down the dose slightly

Much appreciated, Neil! I'll consider adding fractional volume support in the future. Thanks, and be well!

Very clean nice app. I would love to see the option to save calculations and with that to see how many doses are left in the vial.

Many thanks for the kind words, Elizabeth! And I appreciate the feedback as well—a few other people have suggested the same, so I'm considering an update to the app which would add those features. In the meantime, best of luck! – Max
