Femstate Consumer Test Plan V2
CONSUMER TEST PLAN
Femstate™ Phase-Aligned Nutrition Program
Perceived-Benefit Longitudinal Study — Cohort Design, Measurement Protocol & Recruitment Model
Prepared for Internal Review Version 2.0 September 1, 2026
Executive Summary & Objective
This document outlines the consumer test plan for Femstate™, a phase-aligned daily nutrition supplement offering four distinct formulations matched to the four phases of the menstrual cycle (menstrual, follicular, ovulatory, and luteal).
The primary objective of this study is to identify the consumer-perceived benefits of Femstate™ across three complete menstrual cycles vs. a baseline month prior to produt usage. The study will measure what physical, emotional, and cognitive changes women experience while using the product, and isolate which of these changes are meaningfully greater than each participant's pre-Femstate™ baseline.
Core Objective
| Research Questions What changes do women experience after using Femstate™ for one to three complete cycles, and which of those changes are meaningfully greater than their pre-Femstate™ baseline? Secondary objectives: How long does it take for women to experience benefits (this is why testing for three months) What is compliance of women switching at right phase of cycle, and compliance taking daily? Do the devices like Oura show measurable benefits (i.e. better quality sleep) |
|---|
Study Focus Areas
- Efficacy: self-reported changes in energy, mood, bloating, and cramp relief across a full 28–35 day cycle.
- Usability & Compliance: how easily participants transition between the four formulations at the correct time.
- Sensory Profiling: taste, mixability, and smell of each of the four phase-specific powder scoops.
- Biometric Validation: cross-referencing subjective claims against objective wearable hormone-tracking data
2. Study Design & Cohort Architecture
The study uses a three-cohort longitudinal design built around a 28-day cycle framework, comparing Femstate™ against two distinct real-world baselines — women with no existing supplement habit, and women switching from an existing supplement routine.
Cohort Definitions and Base Sizes
| Cohort | Baseline Population | Base Size | Intervention | Purpose |
|---|---|---|---|---|
| A — Femstate Only (Supplement-Naive) No Oura Prod | Women who do not regularly use a multivitamin or daily supplement regimen | 30 with 25 expected completes | Establish pre-use symptom baseline, then introduce Femstate™ | Primary baseline control — true impact on supplement-naive users |
| B – Femstate Only (Supplement-Naive) High Fidelity w/ Oura | Women who do not regularly use a multivitamin or daily supplement regimen | 30 with 25 expected completes | Establish pre-use symptom baseline, then introduce Femstate™ Full Oura biometric tracking + standard consumer claims | Primary baseline control — true impact on supplement-naive users Biometric validation to cross-check self-reported claims |
| C — Switchers No Oura Prod | Women currently taking regular daily vitamins or wellness supplements | 30 with 25 expected completes | Taper off existing comparable routine (where safe and appropriate), then transition exclusively to Femstate™ | Market comparative — perceived value vs. standard daily multivitamins |
| D — Switchers High Fidelity w/Oura | Women currently taking regular daily vitamins or wellness supplements | 30 with 25 expected completes | Taper off existing comparable routine (where safe and appropriate), then transition exclusively to Femstate™ Full Oura biometric tracking + standard consumer claims | Market comparative — perceived value vs. standard daily multivitamins Biometric validation to cross-check self-reported claims |
Note: For Cohorts C and D, existing routines should only be discontinued where medically appropriate. Doctor-prescribed medical supplements must not be stopped as part of this protocol.
3. Participant Qualification Criteria (Screening Protocol)
To ensure data integrity and eliminate confounding variables, all participants must meet the following criteria:
- Age Profile: 25–40 years old (peak target demographic)
- Hormonal Status: Natural, unmedicated cycles. No hormonal birth control (pill, IUD, patch, implant) and no Hormone Replacement Therapy (HRT)
- Cycle Regularity: Predictable 26- to 32-day menstrual cycles
- Lifestyle Match: Active, health-conscious women willing to adhere to a daily supplement routine and daily/weekly/end of month survey logging requirements
4. Measurement Mechanics & Data Stream Integration
Data will be captured through three complementary mechanisms to combine objective physiological signal with subjective consumer experience.
A. Biometric & Biomarker Infrastructure (Cohort B/D Focus)
- Oura Ring (daily, continuous): passive data sync via API tracking resting heart rate (RHR), heart rate variability (HRV), sleep staging/quality, and basal body temperature (BBT) deviations across the 4 phases.
B. Compliance Verification
- Photo Verification: participants upload daily photos of their prepared Femstate™ scoop/beverage or empty phase-specific packaging via the study app to verify compliance and phase-switching accuracy.
C. Consumer Claim Data (Subjective Experience)
- Baseline Surveys: pre-Femstate™ cycle symptoms (energy, mood swings, cramps, bloating, brain fog).
- Phase-Transition Surveys: 3-minute surveys sent at the conclusion of each of the four product phases.
- End-of-Cycle Depth Surveys: comprehensive evaluations after Cycle 1, 2, and 3 to measure cumulative effects.
5. Execution Timeline & Phases
| Timeframe | Cycle Focus | Key Activities |
|---|---|---|
| Days 1–30 (Cycle 1) | Baseline & Study Adaptation | Digital onboarding to surveys; Cohort B tapers off current supplements; Oura API setup. Begin daily survey, ~weekly survey (for each stage), and end of month survey |
| Days 31–60 (Cycle 2) | 1 st Month Femstate Usage | Usability, taste, and phase-transition friction assessed Compliance monitoring; trend identification; evaluate whether benefits (reduced PMS symptoms, steadier energy) compound; cross-reference Oura sleep/temperature data with wellness logs |
| Days 61–90 (Cycle 3) | 2 nd Month Femstate Usage | Continue usage of Femstate and data collection |
| Days 91-120 | 3 rd Month Femstate Usage | Final validation period to lock in statistical significance; biometric correlation; data compilation to answer the core research objective |

6. Key Performance Indicators (KPIs) & Success Metrics
A benefit will be qualified as "meaningful" if it meets the following benchmarks:
- Symptom Reduction Delta: Statistically significant decrease in self-reported physical/emotional discomfort scores from pre-Femstate™ baseline to Cycle 3
- Compliance Threshold: Greater than 85% of participants correctly switching between the four product phases at the correct physiological time, validated by Oura Phase Data
- Biometric Correlation: Demonstrable stabilization of HRV patterns or improved sleep scores during historically difficult cycle phases (e.g., late luteal), via Oura API insights
7. Survey Outline
A series of surveys will be deployed to get data at various stage of study.
- Pre-Study Survey (one time) baseline Assessment at beginning if study
- Daily Pulse Survey – (daily) focused on compliance and consumer claims daily
- End of Phase Survey (about 1/week)
- End of Cycle Survey (about 1/month) overall assessment of cycle)
- End of Study Survey (one time) Assessment at experience with Femstate
