Frequently Asked Questions

How much does a study cost?
It depends on study design, sample size, and endpoints — but most studies fall between $25K and $100K. Your proposal will include transparent pricing with no hidden fees. We don't nickel-and-dime you for amendments or data exports.
How long does a study take?
Most studies run 4-12 weeks of active enrollment and data collection, plus 2-4 weeks for analysis and report delivery. From kickoff to final report, plan on 2-4 months total. We'll give you exact timelines in your proposal.
Do I need IRB approval?
We handle that. Every Citruslabs study goes through IRB review — it's included in the price, not an add-on. IRB approval strengthens your claims and protects you if anyone challenges your study design.
What if my product doesn't show results?
We report what the data shows — period. But even when primary endpoints don't hit statistical significance, participant perception data often yields strong, defensible marketing claims. You'll have something you can use either way.
Is this going to be a sales call?
No. You'll get a written proposal by email with study design, timeline, and pricing. If you want to talk through it, we're happy to hop on a call — but we won't chase you. Ever.
Can I use these claims on Amazon?
Yes. Our reports include a claims appendix with copy-ready language specifically designed for product pages, Amazon listings, and advertising. We also include regulatory guidance so your team knows exactly what's compliant.
I'm not sure I'm ready. Should I still reach out?
Absolutely. A lot of our best clients started with "I'm just exploring." Getting a proposal costs you nothing and gives you a clear picture of what a study would look like. No commitment.
What makes Citruslabs different from other CROs?
Three things: speed (most studies launch in weeks, not months), the platform (real-time visibility into your study — not PDF updates), and the deliverable (a report with claims appendix and regulatory guidance, not just a data dump).
