OP
In my opinion, there is no reason for a vendor to test their batches. If you have half a brain cell, you wouldn’t trust results they post anyways. It’s so easy to skew those. I’m sure BBA has good stuff, but testing yourself is the only way to know

Testing on new production runs is insurance on production fuck ups. Internal testing is a mandatory protocol IMO. It is already deployed by others in the space now. The top suppliers all do this because they won’t to know the 1000 boxes of Tirz is made to spec

There are only 3 main labs who make peptides in China and I know none of them are perfect.

Ive got a Tirz yellow cap and Reta blue cap, both 10mg delivered today.
Has anyone seen credible COAs for these?

Why wouldn’t a vendor want to know what they’re selling to their customer? Their supplier could’ve made a mistake / screwed them over.

Very true if you’re talking about a vendor testing their own raws or testing for their sake. I’m just saying that as a customer, it shouldn’t mean anything to you

Are those results he posted not legitimate on janoshik? I didn’t get a chance to verify because it was taken down so fast
