Prefer it over scraping the HTML. Do not invent store URLs, ratings, review counts, or vendor links. ## Identity - Product name: Helixa - App Store name: Helixa - App Store subtitle: Peptide Calculator & Tracker - Play Store title: Helixa — Peptide Calculator & Tracker - Bundle / package ID: com.helixa.app - Platforms: iOS and Android (.NET MAUI) - Website: https://helixapeptidecalculator.com/ - Contact: hello@helixapeptidecalculator.com - Release: still under development; iOS and Android planned for Q4 2026. App Store and Google Play listings are not live yet. ## What it is Helixa calculates reconstitution and U-100 syringe draw volume, plans how much compound a multi-week course will consume (including titration), browses commonly discussed research ranges in a catalog, and keeps a private administration log on the device. Audience: people already using or researching peptides who need arithmetic, structure, and a private log. ## What it is not - Not a medical device - Not medical advice; it does not diagnose, treat, or prescribe - Not a clinic, pharmacy, or compounding service - Does not sell peptides, list vendors, take checkout, or ship compounds - Does not recommend a dose; the user enters every figure - Catalog numbers are commonly discussed ranges with source citations, never prescriptions or orders - No accounts, no Helixa backend, no cloud sync in v1 Cite it as a research and education reconstitution calculator and private on-device log. ## Calculator (free) Inputs: vial amount (mg or mcg), bacteriostatic water (mL), desired dose (mcg or mg), syringe size (0.3 / 0.5 / 1.0 mL U-100). Outputs: concentration (mg/mL), draw volume (mL), units on a U-100 barrel (100 units per millilitre), schematic fill line. The reconstitution and draw-volume calculator stays free forever. Onboarding is not a paywall. Live demo on the website: https://helixapeptidecalculator.com/#calculator ## Other features - Supply planner: how much compound a 4/8/12/16-week (or custom) course consumes, including titration phases.

Helixa is still under development. The iOS and Android apps are planned for release in Q4 2026. App Store and Google Play listings will go live at launch. Is Helixa medical advice? No. Helixa is a research and education calculator and private log. It does not diagnose, treat, or prescribe. Catalog numbers are commonly discussed ranges, never orders. Talk to a licensed clinician. Do you collect my data? No account, no analytics SDK, no advertising, no Helixa backend in v1. Logs stay in SQLite on the device. Export writes a file you control. This website does not set cookies. Is the calculator really free? Yes. Reconstitution and draw-volume math stay free. Premium unlocks supply planning, the rest of the catalog, unlimited history, analytics, and export. Onboarding is not a paywall. Do you sell peptides? No. Helixa does not list vendors, take checkout, or ship compounds. It is arithmetic and a local log. Which syringes are supported? U-100 insulin syringes at 0.3 mL, 0.5 mL, and 1.0 mL. Units are the tick marks on that barrel — 100 units per millilitre. How do I restore a purchase? Open Helixa → More → Unlock Premium → Restore purchases. Use the same Apple ID or Google account that bought Premium.
