Built-In Calculator

Reconstitution & Dosing Guide

The app includes an interactive calculator that handles the math automatically. Here is the underlying methodology.

01

Calculate Total Doses

Vial Strength (mg) ÷ Desired Dose (mg) = Number of Doses

Example: 10 mg vial ÷ 1 mg dose = 10 doses

02

Calculate Volume Per Dose

Total BAC Water Added (ml) ÷ Number of Doses = Volume per Dose (ml)

Example: 2 ml water ÷ 10 doses = 0.2 ml per dose

03

Convert to Syringe Units

Volume per Dose (ml) × 100 = Units on a 1 ml Insulin Syringe

Example: 0.2 ml × 100 = 20 units

Administration Routes & Bioavailability

💉
Subcutaneous~100%

Gold standard for most peptides. Inject into fatty tissue of the abdomen, thigh, or deltoid. Rotate sites to prevent lipodystrophy.

💪
Intramuscular~100%

Used for compounds like Testosterone Cypionate. Slightly faster absorption than subcutaneous.

👃
Nasal Spray1–10%

Best for brain-targeting peptides (Semax, Selank, PT-141). Convenient but requires higher doses.

💊
Oral / Sublingual5–36%

Standard oral is poor due to gastric breakdown. Sublingual can reach up to 36% for select formulations.

🧴
TopicalVariable

Used for GHK-Cu and collagen peptides in skincare. Penetration depends on molecular weight and formulation.

App Architecture

Platform Blueprint

A full-stack, PWA-enabled platform designed to guide researchers from goal identification to optimized peptide protocols.

Personalized Quiz

A multi-step onboarding quiz identifies user goals, experience level, and budget — then maps responses to the optimal peptide protocol using a weighted scoring engine.

Peptide Database

55+ detailed peptide profiles covering mechanism of action, clinical research summaries, side effect profiles, dosing protocols, and administration routes.

Reconstitution Calculator

An interactive tool that calculates BAC water volume, dose per injection, and syringe unit conversions for any vial strength and desired dose combination.

Protocol Tracker

A calendar-based protocol manager that tracks injection days, cycle lengths, and mandatory rest periods — with push notifications for dosing reminders.

Holistic Stacking

Evidence-based supplement stacks, dietary protocols, and exercise recommendations tailored to each peptide to maximize therapeutic outcomes.

Smart Reminders

PWA push notifications deliver context-aware dosing reminders — fasted morning injection, pre-bedtime dose, cycle break alerts — to keep users on protocol.
