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.

Peptide Protocol is a peptide and GLP-1 dose tracker. Log every dose in seconds. Track vial inventory and get refill alerts. Rotate injection sites. Check in on energy, sleep, appetite and weight, and see what is actually changing week by week. The Reconstitution Helper does the arithmetic on the values you enter yourself — units, volume and doses per vial. Works with Ozempic, Mounjaro, Wegovy, Zepbound, Retatrutide, semaglutide, tirzepatide, BPC-157, CJC-1295, Ipamorelin, GHK-Cu and 30+ more compounds. Built for the biohacking and longevity crowd: pause your protocol with a return date and it auto-resumes the day you choose. Rotate injection sites, review side-effect patterns week by week, and keep every record local-first on your device. WHO IT IS FOR Peptide Protocol is designed for people who want structure, clarity, and better protocol follow-through without spreadsheet complexity. IMPORTANT Peptide Protocol is for personal organisation and self-tracking only.

Verdict
The clearest difference is monetization model: Peptide Calculator + at freemium against Peptide Protocol's subscription. Peptide Calculator + also leads on ratings volume (58 vs 12) and iOS requirement (15.1 vs 18.0). Peptide Protocol's advantage is review sentiment (100% vs 75%) and rating (5.0 vs 4.7). On price, update cadence, ads and in-app purchases there is nothing between them.
