Choose real-time, accelerated, or both

Last updated: October 9, 2026

On the Study type step you decide how each product is tested and for how long.

The two study types

  • Real-time is stored at 25 °C and 60% humidity. It's the long-term test that validates your shelf life.

  • Accelerated is stored at 40 °C and 75% humidity. It brackets the data while real-time runs.

Most studies run both together. Running both is also more efficient: the accelerated T0 baseline reuses the real-time T0 result, so you aren't charged for it twice.

Set up each product

  1. Under Apply to all SKUs, click Real-time, Accelerated, or both to set the same type on every product at once. Skip this if you only enrolled one product.

  2. In each product's row, turn Real-time or Accelerated on or off.

  3. Set the duration for each arm that's on.

    • Real-time duration is in months. For a four-year shelf life, select four years.

    • Accelerated duration is in weeks.

  4. Optionally, enter a Lot number. You can also add it after the quote is approved.

  5. Click Continue.
