Protocol
Protocol is a precision injection tracking application serving a spectrum of users from TRT patients to performance athletes. The engagement centered on end-to-end product design: translating highly complex, personalized health data into an interface that balanced clinical accuracy with consumer-grade usability. Core work spanned information architecture, a scalable component system, longitudinal data visualization, and a retention-optimized onboarding flow — all executed within a 10-week sprint.

Project Overview
Client: Protocol
Industry: Health & Wellness, Self-Quantification
Timeline: 10 weeks (2026)
My Role: Lead Product Designer
Protocol is an industry-grade, top-charting health tracking application built for precision self-optimization. Designed for everyone from everyday wellness enthusiasts to competitive athletes and clinical users, Protocol provides a best-in-class interface for logging, visualizing, and managing injection-based protocols — including testosterone replacement therapy, peptide stacks, and performance compounds. The product demanded a design system that could hold both the intimacy of personal health data and the rigor of clinical-grade tracking.
Design Solution
Conducted deep user research across three distinct personas, recreational wellness users, performance athletes, and medically supervised patients; mapping divergent mental models into a single, coherent information architecture.
Architected a high-density yet visually calm logging interface, leveraging progressive disclosure to surface relevant inputs contextually without overwhelming first-time users or creating friction for power users operating complex multi-compound protocols.
Designed a modular compound library with extensible entry states, accommodating custom dosage units, injection sites, cycle phases, and frequency cadences — ensuring the system scaled gracefully across use cases without compromising interaction fidelity.
Established a data visualization layer translating longitudinal injection history into actionable insight — cycle timelines, dosage trends, and compound overlap — empowering users to self-audit adherence and share protocol summaries with healthcare providers.
Built a friction-minimized onboarding experience with pre-configured protocol templates and contextual empty states, dramatically reducing time-to-first-log and reinforcing habitual engagement patterns from day one.
Outcomes
Elevated retention through habitual design: Users returned daily due to a logging experience that felt fast, personal, and rewarding rather than clinical or burdensome.
Collapsed the gap between casual users and advanced athletes within one unified interface — a significant information architecture achievement given the breadth of protocol complexity across the user base.
Enabled meaningful provider-patient communication by giving users exportable, structured data summaries that brought credibility and continuity to medical consultations.
