Effect of injecting too much oil??

[Cuz]

1" 25g
used test prop 100mg/ml
sterilized the injection site with alcohol pad of course.

has been about 15hours ago.

everything was sterile

has done some subQ with prop.

the small lump under the skin look alike but on my arms its wider and longer.

I don't know man, having lumps on your arms does not sound good bro when you are injecting in your mid delt?. Was it your first time into the delts?
