Peptide Calculator + takes the guesswork out of peptide dosing, reconstitution, and mixing — so you can focus on your protocol, not the math. Dose Calculator Enter your vial size, bacteriostatic water volume, and desired dose to instantly see exactly how much to draw in your syringe. The app displays units, volume, concentration, and total draws per vial — everything you need at a glance. Supports multiple syringe sizes for precise measurements. Blend Calculator Need to combine multiple peptides like BPC-157 and GLP-1 agonists in a single injection? The blend calculator shows per-peptide and combined draw amounts, making multi-peptide syringes straightforward and accurate. Reconstitution Calculator Not sure how much bacteriostatic water to add to your vial? Enter your desired units per draw and the calculator works in reverse — telling you the exact dilution volume needed for your target concentration. Whether you're working with semaglutide, tirzepatide, or any other peptide, Peptide Calculator + handles the dosage math so you don't have to. Features • Peptide dose calculator with syringe draw amounts • Blend calculator for mixing multiple peptides • Reconstitution calculator for precise dilution • Support for multiple syringe sizes • Clean, intuitive interface Accurate dosing, simple math — built for your protocol.

Verdict
The clearest difference is update cadence: Dosebook at daily against Peptide Calculator +'s every 8 days. Dosebook also leads on review sentiment (100% vs 75%) and rating (5.0 vs 4.7). Peptide Calculator +'s advantage is ratings volume (59 vs 7). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Peptide Calculator + sells 5 in-app purchases, starting at $3.99 per 7 days and Dosebook sells 2 in-app purchases, starting at $7.99 per month. Whichever you choose, the download price is not the number that matters.
Dosebook holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Peptide Calculator + has 59 ratings behind it against 7, so its average is the more settled of the two. Written reviews point the same way: 75% of Peptide Calculator +'s written reviews are positive against 100% of Dosebook's.
Peptide Calculator + ships an update every 8 days, Dosebook daily. Both last shipped on October 24, 2026.
