Has anyone ever heard of or used Maxmicrobe or Myco Chum?

I got these free samples today when I visited the only hydro store in my state. I was pretty excited to find it and it's only an hour from home. He gave me a few different samples of products that basically look like they're microbe food. I've not yet stated growing with living soil, but the plan is to use Coots recipe and irrigate with blumats. Really just waiting on the Malibu compost from the hydro store. Are products like these redundant if I'm already brewing and using compost teas? The way I understand it is they're basically compost/microbe tea concentrated and in a bottle.

Here's the samples I got.

Real Growers Recharge - Soil Microbe Superpack - Natural Plant Growth Stimulant (8oz) https://a.co/d/ivLiUTL

MYCOCHUM ….. yes.

A lovely inky solution. Basically a fish / kelp / molasses bump for soil mediums.
I use once a week. Even in a diluted light to medium ratio for hempy buckets.

I use cultured biologix nutrients along with there ez teas and I use that on my tea days , with amended soil .
