Tasting and smelling Sust250 after the injection?

[surfwrv32]

Has this ever happened to anyone. My friend said it happens every time (He's only on shot 5) and thinks it's a bad batch? We have been getting from this source for years without any issues and great gains but I personally don't have any experience with Sust.

I have been getting this everytime I inject my test e. The gear is good to go but I do get a faint solvent smell/taste while pinning. I aspirate every time so I know I'm not shooting into a blood vessel. My guess is that a trace amount enters the bloodstream.
