(US) Vendor gear found with dissolved brewing equipment (Plastic)

Plenty of people backload slin pins for 1-3 weeks with no issues. Make sure gear is good and it doesn't contain EO or super solvents. I'd backload a syringe today and leave it in the drawer for 15-20 days.

After that inspect it carefully, if you see any parts of the rubber missing or anything weird toss it and abort the idea, otherwise you'll be fine for 1-2 weeks worth backloading.

Off course with naked eye no one can be 100% sure but if we talk about chunks of rubber they won't even pass from a 29-30G needle. Proceed with caution xD

Obviously, you need some good quality syringes like BD, B.Braun, Nipro etc..avoid dirt cheap Amazon or Chinese ones.

I personally do backload carnitine and glutathione injections and store them in the fridge. Really does save alot of time with daily pins.

It's water based tho, close to no solvents involved.
 
I'm trying to learn as much as possible here and my skill set is definitely not in the sciences...so if I wanted to avoid the potential issues do I avoid gear made with bottle top filters? All bottle top filters or specific ones? Do I look for pump systems with capsule filters? I'm fine digging around but any help to know what to look for would be great.
 
I am looking for veterans who have purchased gear from the below vendors from Jan-Sep this year to send in their sealed vials for testing.

Test to order is HPLC+GCMS

Primal
Mast P200
I'm no veteran but I'm willing to help out and I'm 99% sure I have the Mast P200 from that timeframe.
Can check a bit later although I've never sent anything in to Jano so I might have a couple questions.
I probably also have the NPP200. Any interest in me sending that in too?
 
The contaminated gear came from primal? Or am I reading it wrong
Yes the Tren 400 in 2 batches
Everyone here is trying to see if other high concentrations have the plastic in it as well. But requires GCMS testing from jano

From my understanding it’s from elevated levels of BB used to make high concentrations. It’s degrading / melting the filter top they use & that’s being trapped in the oil as they’re brewed/filled.
 
So I will ask again.



I provided the NIST mass spectrum and @proton provided Jano's mass spectrum for peak 3.






Next would be ordering a reference standard and generating another mass spectrum. What else shall we do to confirm the identity of this compound?
 
This is making me very thankful that the high concentration gear wasn't offered at any discount on a mg for mg basis, which lead me to purchase the lower/standard concentration stuff. It's kind of crazy to me how so many UGL's have been using various materials in their filters, stopper, etc... that are simply not compatible with benzyl benzoate, especially when higher concentrations of it are needed/used.
