Plastic taste after injection

[blazencruise]

Hello, I've used yms, pharmacom, euro-pharmacy, all without issue, they are definitely high quality products. Recently I picked up some pharmaqo test, and I've noticed with this product when I inject my ass cheek I get a plastic taste in my mouth for a short while. It has only happened with this particular lab. Anyone know what this is??

Interesting. Haven't changed injection sites and only have this with this particular brand and it happens every time. Maybe I'm just unlucky....
