How long does each stage take?

Study design takes 1 to 2 weeks, IRB approval typically 2 to 4 weeks, recruitment 4 to 8 weeks, data collection 6 to 14 weeks depending on study type, analysis 1 to 2 weeks, and claims and marketing assets the final 1 to 2 weeks. Most consumer perception studies finish end-to-end in 4 to 8 weeks; randomized controlled trials in 12 to 16 weeks.

Can I expedite a Citruslabs study?

Yes. Citruslabs offers an expedited timeline that compresses durations roughly 25% by moving the study into a priority queue across protocol drafting, IRB submission, recruitment, and analysis.

What happens after the study report is delivered?

Sponsors keep the dataset and the report in full. Citruslabs ships marketing-ready claim language reviewed for FTC and FDA best practices, supporting graphics, and optional Tested Seal usage rights for packaging, ads, retail, and PR.

The six stages of a Citruslabs study

Study Design & Protocol — We translate your product and claim goals into a defensible protocol — endpoints, sample size, inclusion criteria, and statistical analysis plan.
IRB Approval — Independent ethical review of your protocol. We handle the entire IRB submission and typically move weeks ahead of what most CROs promise.
Participant Recruitment — We enroll qualified participants from our proprietary database and decentralized recruitment channels. Faster enrollment and more diverse panels.
Data Collection — Participants follow your protocol from home. We capture validated questionnaires, biomarkers, wearables data, and AI-verified photos in real time.
Analysis & Results — Statistical analysis tied directly to your endpoints, with a full report your team and your reviewers can defend.
Product Claims & Marketing Assets — Marketing-ready claim language for PDP, Amazon, ads, and PR — reviewed for regulatory compliance, plus the Citruslabs Tested Seal if your product passes.
