How often does Steroidify update lab tests? Concerned about consistency.

I appreciate Steroidify publishing lab tests, it's definitely a step above many other sources. However, I'm a bit of a skeptic when it comes to quality control over time. Products can change, batches can vary.

Does anyone know how frequently Steroidify updates their lab tests for specific products and brands? Is it per batch, or more of a periodic thing? I'm always a bit concerned that a test from 6 months ago might not reflect the current batch I'm receiving.

Has anyone ever received a product from them that felt 'off' despite there being a positive lab test for that item on the site? Just trying to understand the real-world consistency. It's a big investment, so want to be sure.
