I just added masteron into my cycle and took my first pin of it about 20 minutes ago. After injecting I pushed on the plunger to see if i left anything, and as usual there was one drop of oil left in there. It dropped on the table and i wiped it up, didnt think anything of it. After awhile I kept noticing this horrible smell, sort of an indescribable smell, but for lack of a better word it smelled like ass. I looked around and found that the residue of the oil was the source of the smell. I smelled the top of my mast vial and it smelled exactly the same. I have never noticed any strange smell from gear, so this is very odd to me. Has anyone experienced this?
