anyone experienced this

[mowla]

the last twice , when i have injected into my left shoulder, there has been what looks to me like a yellowish substance going into the barrel when i aspirate the syringe, it certainly doesnt look like blood. i have got no pain in my shoulder so i don't think i have any sort of infection in there , i'm just wondering if it is blood but looks a diferent colour when mixed with the sustanon
any ideas?
maybe someone replaced my blood with engine oil through the night!!!

sounds like fat to me, how hard are you drawing back the syringe when you aspirate. You barely have to pull it back at all

and make sure your rotating injection sites.i try not to hit the same spot in 1wk it can get tuff with everyday injections.blood is red and looks little balls of red in the syringe almost black you cant mistake it
