What is the other <1% made of that isnt tirz in testing? Is it still possible for it to be something we need to worry about?

I see the tests are all 99%+, but not 100. Still worried about what that could be.

Bonus question: just ordered from amopure. Do they give you the batch number with your order?

Amo doesn't give batch numbers currently, but I just saw on their website earlier that batches made after mid October will have them.

The 1% is probably degraded peptide or peptide fragments, nothing to worry about. However that total 100% refers to the target peptide, there is other stuff in the vial that isn’t included in a purity test. So if you had 1mg of perfectly pure tirz in a base of 100mg of cyanide, the test would show 100% purity because it isn’t looking for that cyanide.

Edit to add: the take home point is that these tests will help you know that the vendor sold you what they said they would, but it doesn’t mean it is pharma-safe. For that you need to spend pharma money. That’s the trade off we are making here, best to be clear-eyed about it.
