Small Lumps in Oil?

Hi all I have about 2mls left of a vial of test c. I’ve noticed 3 or 4 grey/dark lumps inside the vial today, not seen them before. What are these likely to be from and does it mean I should bin my vial and start a new one?
Obviously I’ll check the lumps don’t end up in the syringe if I do use the rest of the vial but it’s my first cycle and first time I’ve seen these so want to make sure the oil is still ok to use
Thanks all

Post a clear picture. It’s either crashed gear or mold. One is not an issue the other is.

Idk man that’s not any crashed gear iv ever seen before. Shit looks like bacteria or mold. I probably wouldn’t use it

This is beyond my level of gear knowledge and experience maybe someone else will chime in.

Is the vial somehow exposed to the atmosphere/air? I would play it safe and throw it out either way.

Not any more than normal vials, it’s got the rubber stopper and the cap over it, I put it back in its box too. I’ll throw it out and start a new vial, I’ve injected this today with the lumps in there but I made sure there was none in the syringe, hopefully no infection happens from today’s dose…

I always inject the same amount of air that I intent to draw. Is this a bad practice? Just makes it easier to draw.

Not really sure what I’m looking for in the photo, but small dark grey lumps are likely to be parts off the rubber stopper, punched through by the needle.
In that case nothing to worry about.

Second for rubber stopper. Find a source that uses silicone stoppers. Way better.
