Yes, you have to test it because the quality and purity what you get isn’t tested.

When someone sells something and they make a statement about the product (e.g. “tested”), they don’t mean the customer has to test it.

Not to defend buying research chemicals of unknown safety, but that isnt what he said. Independent labs test for purity and provide certification to the companies that sell them. Those certifications can be verified by anyone. So its much less trust necessary to know what you are getting.

How do you know if the shipment you received was in the same batch that was tested?

Sure, you might be given a "batch number" that matches up with what they said was tested, but that's putting a whole lot of trust in the seller.

Group buy, the organizer tests randomly pulled vials, then ships out the kits to the end customer.

Or you test a vial from your own kit. Expensive but still cheaper than compounded GLP-1.

Or you roll the dice and assume that everything ahipped out about the same time with the same cap color is the same batch.

Or you buy from nexaph.

Everyone has to decide their own comfort zone.

What's the name of one these independent labs? I would like to read up on them.

As someone else said, Janoshik is popular. But there are others of course. Peptide Test, or Finnrick come to mind.

Janoshik

Where are they getting it tested?

3rd party labs with HPLC testing.

Janoshik is a longtime name in this space, originally catering to bodybuilders buying anabolic steroids and HGH.
