Visible hole in rubber stopper after fifth injection. Vial contaminated?

I've done 5 injections from this vial, after the last injection I noticed a small hole in the rubber stopper. The 4 times before that the stopper seemed to seal up completely. I use a 22g needle to draw.

Is this normal or is the vial possibly contaminated now?

It's a Pfizer 10ml vial, I'm supposed to take 5 more shots from it before getting the refill.
Hoping I don't have to go back to the pharmacy. They treated me like this was a prescription for heroin the last time I was there.

I do mot see a problem. That rubber is thicker than you think. But, i stopped usimg th elarger needles to draw up for that reason. Also i dont poke in the same spot each time
 
There should be no issue with the small hole. I do daily injections and I actually try to reinsert the needle in the same spot every time.

I would not worry.....if anything why are you drawing with a 22 gauge (although it may be quicker) as it will be more prone to leaving a bigger hole in the neoprene rubber compared to using a fixed insulin syringe 27-31 gauge.

Even though you are only drawing once weekly (god forbid one was drawing daily or EOD with a 22 gauge) you would be better off switching over to using a fixed insulin syringe (draw/inject) with the same needle.....less waste and you eliminate the 2 step plus switching out needle if you are injecting with a different gauge.
 
Thanks for the replies.
I wasn't sure if the rubber stopper is supposed to seal up completely.
Didn't notice any holes until now.

It's not leaking and no signs of rubber inside the vial.

I have some 25g needles i'll switch to for drawing. I've been injecting with a 23g 1" needle (on BD 3ml syringe).
For some reason the plunger is slow to go down even with that gauge.

Do you know any good Canadian sites for insulin syringes?

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
