Some of these are easy to rule out, obviously. DHB does require higher solvent content, so maybe high BB content along with a stopper that had some manufacturing issues, an over crimp, the vial being stored on its side allowing more time for the BB to attack the rubber, or other combined factors lead to this?

It only needs like 2-3 percent more solvents, still lesser than HC gear. I doubt it makes a difference...

This is really pronounced when using something like tra as you can visually see all the dark orange sink to the bottom.

That should not be happening, it's a homogenous solution. What your seeing is some form of crashing or poor quality tren with tren base mixed in it..

Sourcing from the Wuhan Discount Rubber Stopper Company probably the biggest factor.

Looks like USP/FDA has identified rubber oligomers leaching from butyl rubber stoppers into injectables as carcinogens. and established limits of exposure based on how frequently injections are expected of drugs containing them:

Coated stoppers prevent these carcinogens from getting into the solution.

I all seriousness what is it like using a 10ml for an injection? I feel like when I filter my oils with one my thumbs hurt from pressing the plunger so hard.
True and it def is a bit harder to inject

A few months ago I fractured my left scaphoid and the resulting inflammation compressed my ulnar nerve, so I've been dealing with grip weakness and inability to use my ring finger + pinky. So when using that hand for my right delt I'd use the 10ml since the bigger syringe is easier to handle with only a few fingers. And heating the oil up made pushing a lot easier.

The neuropathy is almost pretty much gone now but I'll still use the 10mls to pin my ventroglute just because I have so many and have had no issues with that
 
These pictures were taken about an hour after the previous ones posted.

No pressure inside the vial, just a bad stopper.

This obviously needs to be addressed and for all the doomsday preppers preparing for the gear apocalypse, check your stash for failing stoppers.
This topic is right on time. I've noticed my stoppers starting to bulge and tonight I'm swapping with some pfizer / hospria vials.

I bought these when I was only using HGH and didn't have any oils yet. Wish I had ptfe's. I'll order those next.

How are the stoppers on the Pfizer's? I was eyeing the 30mls but I couldn't find the spec sheets if it's PTFE or normal rubber. Those cost more than PTFE lol

The stoppers are nice. Thick and tough material. Slightly concaved shape

They don’t give much info on the company website. Only mention of material is on the vial. It says natural rubber latex has not been used in the manufacture of the vial.

I’ll send an email asking if they are ptfe but if it’s not on a a spec sheet I’ll probably get a generic answer.

I got these from mountainside for $27 per pack of 10.

Going forward, I won't order anything that doesnt have a ptfe stopper.
At the very least a quality USP class 6 bromobutyl stopper.

The RTS are much lower unit price than RTU.

https://qcvialz.com/16-vial-stoppers

unit price: 14 ct vs 37 ct

These are equivalent to the stoppers on the Ultra-Spec or ALK vials, although I believe the newest ALK vials have Flurotec barrier.

Alot of links in that filtering finished oils thread. Also deals to be had on "expired" FluroTec stoppers.

@Primal_Pharma were there any issues with the supposed mast e drop or will we still be seeing this soon? And possible eta?
Just waiting on our source to give us another update. Before end of year still seems like a very real possibility.

Also, looks like we need to roll out these Novapure stoppers as soon as possible. Will update you all when that happens!
 
Welcome to the board, Primal Pharma! Good to see another source willing to put their products to the test. Looking forward to seeing how things go.

Safe to assume this isn’t high concentration issues considering these vials are cyp 200 and 50. What’s your batch numbers on these? Wonder if it correlates to the DHB batching timeline. One stopper is a one off and can be attributed to user handling but multiple vials from different users something more perhaps? Is there really anyway to determine cause or are there too many factors based on region, shipping, altitude of lab etc…? I mean in almost two decades of AAS purchasing I’ve never seen it. Not accusing of malpractice just generally curious. What’s the significance or is it nothing of concern? Lots of experience in here have others seen this before?
 
Thanks for that.



So I wonder if these initial stoppers on the early batches were actually butyl rubber?



I thought that was the silicone stoppers that were used for a few batches?


Thanks again for taking the time to capture the stopper deterioration. How many times did you wipe this vial stopper with 70 or 91% IPA since you had it?

Is that what I think it is at the base of the stopper over to the right inside the vial? :oops:
This would be 2nd time, once with a regular 70% wipe a few months ago then this time with 91% because I'm out of wipes.

Guess I'm moving up the schedule on poppin vials and filtering. Any recommendations on binge TV to help pass the time?
