Sustanon Making Me Sick?

So I’m on sustanon and have a weird issue.
It seems to give me respiratory infection type symptoms, like making me sick.
When ever I inject it, I’ll get the next day or sooner. It feels like my lungs and airways are irritated and I have to cough up slime/mucus/whatever the correct translation is.
Last time I tried sustanon, i got slight fever for weeks until I decided to stop. I had been thinking that it might have been a coincidence, but apparently not.

Anyone have ideas why sustanon could be causing this?
I was guessing the carrier peanut oil but allergy test showed no reaction to peanut.
Could benzyl alcohol be somehow irritating my body?

Are you using pharma or UGL?

Something in the mix is setting your body off. Carrier oil, solvents, etc

If it’s not a prescription which I’m guessing it’s not, it could be contaminated with something. I would discard it at that point.
