red spot on bicep

alright guys last question bout my damn friends gonna make them get on here themselves. but a buddy of mine is taking test prop and he did a c and a half in his delt. this was yesterday well today he noticed hes got a big lump and about a 4 inch red cirle on his outer arm by his long head any ideas why this happened??? i was lost didnt know or never seen this happen shoot in delt and bi gets sore and red let me know what you think guys thanks alot.

It might be an infection....but probably not.

Damn near every shot of prop I put in my delt or tri, would swell up and be a little red. This happened even as I got "used" to the shots.

It never really hurt alot though. It got better as the days went by and was red and warm....but never infected.

where in his delt did he shoot it?

a little more anterior i told him to try to stay in the middle where i always never have a problem. but thats the thing its the delt lol and his bi swoled up thats why i was stumped if he would have lumped up on his delt common sense thing.

I get this too-- but this may be due to how fast he injected. Take your time with all injections.

It's the alcohol and the ester in the prop. The ball is the oil forming a bolus - always happens with test. The oil bolus dissapears after a few days. That's why the red spot - small muscle group it's having a lot to deal with right now - prop injections help scar tissue develop very easily, so be careful.
