Until recently, I was using US based resellers like Atomik Labz. Recently, I ordered Tesamorelin 10mg from Jinjier @ WBS. Order arrived quickly and in good condition. Vials were inspected and immediately placed in freezer at 0F. Went to reconstitute a vial last night with a fresh bottle of Hospira BAC. I used 2mL like I have always used previously. Within minutes the vial was a lump of gel. No liquid was left. I have only ever had this issue with AOD9604 before. So, i naturally assume something must Brute Enforcer Emeritus wrong with the peeptide. Shouldn't be the water. But maybe it is. So I get another freshh bottle of Hospira BAC and a new vial of WBS Tesamorelin 10mg and try again. And sure enough, within minutes, it is gel.

So, I reach out to Jinjier @WBS and include pictures and her response was "What did you not use AA?"

Does anyone else here use Acetic Acid for Tesamorelin? I have never. Does anyone else here have any recent WBS Tesamorelin they want to test and see what happens?
 
I don't know, but I would test the pH of the gel, if you still have it.

Maybe WBS is right about pH being a factor:
Only time I get precipitation is when the pH isn't appropriate for the peptide, like cagri and IPA a especially sensitive
OTOH:

I was told by the vendor not to adjust the pH it may cause it to gel.
As others have said, I mix my tesa with 2ml or bac water to 6mg and experience no sting at all. I've been driving tesa for four months.

They were told by their vendor to add the acetic acid to tesa (which already gelled?), and it apparently worked.
I added some AA and it half turned to liquid and the other half stayed gel. Maybe something was bad with these Hospira bottles. These 5 bottles were delivered in an envelope and left in a mailbox in 90F+ heat for about 8 hours. Maybe it affected it in some way. Maybe it's counterfeit. WHo knows these days? I just tested the pH of the BAC that WBS sent. It was a 10. A 10!
