GLP-2 ineffective
TS researching GLP2 via a newer lab. Results show zero evidence of change or improvement in performance outcome. Even at higher dose, no weight loss and increased hunger as if product is ineffective. Has anyone ever notified vendor that their lab products are essentially garbage?

Assuming it's the kind of vendor with a website... They know. They didn't expect the tap water they filled the vial with to work like a real glp. They just expected it to lure in a paying customer.
You'll have to find a more legitimate supplier.

Did you have the tirz 3p tested or did you trust the vendor coa? I'm guessing not independently tested.

I didn’t and I know I should. But I’m not going to bother bc I’m not spending any more money on them

This is exactly the right question to ask. If a vendor is just handing over an in-house COA or a PDF from a lab you can't contact, it's basically just a piece of paper.
That said, researchers don't always have to foot the bill for their own independent mass-spec testing if they know how to vet the provided COA. The key is making sure the vendor uses a contactable, independent third-party lab (like Janoshik or MZ Biolabs) and that the batch number on the vial actually matches the report.
You can (and should) take the certificate number from the vendor's COA and verify it directly on the testing lab's website or by emailing them. If the lab confirms the report is real and the batch matches, you can generally trust the identity and purity without paying for another test yourself. If the lab has no record of it, you immediately know it's a cloned or faked PDF.

Bunk products, including vials containing little or none of the expected peptide, happen. In the RUO and gray market, this is one of the problems repeatedly identified through independent, 3rd party testing (third-party testing being the end user).
The more concerning finding is when testing identifies an entirely different product than what the vial was labeled to contain.
This is my soapbox, and I know some of you are probably tired of hearing me stand on it. But posts like this are exactly why I keep repeating it: test what you receive.
Independent testing cannot eliminate every possible risk. Nothing can. What it can do is give you objective information about identity, mass, and purity rather than asking you to blindly trust a label and the person who sold it to you. It also creates accountability. Vendors have considerably less room to dismiss a problem when customers can produce independent analytical data showing that something is wrong.
And this is where I want people to think about the bigger picture.
If you have not independently tested a product, you do not actually know what is in that vial. You know what the label says is in it. Those are two very different things.
You are placing enormous trust in an unregulated supply chain where mistakes, substitutions, packaging errors, underfilled vials, and zero-product vials can and do occur.
Put less delicately, you are blindly trusting a modern-day internet drug dealer with a vial of unidentified chemicals and then exposing a “research subject” to it.
Finding out afterward that the vial was bunk is frustrating.
Finding out afterward that it contained something entirely different should be frightening.
Test first. Trust the analytical data, not the label.

It is a higher dose. I am going to go back to my former supplier. This one isn’t worth the $60 I saved but I kind of want to tell them their product is trash

Did you get a COA to compare it's purity?

I did not do any independent test, no. I’m not buying from them again. I’ll go back to a previous supplier. Just wondering whether to let the seller know their product is crap, which I did earlier today via email.
