Why gear came back in syringue after injecting??

[Elias]

I was injectin in my delt, did aspirate no
Blood came out and while injecting the plunger in mid way was coming back up, its like i was aspirating, dunno maybe my muscle was a bit tensed. After finishing the injection i waited for 5 secs before taking it out and the plunger aspirated some gear. Any ideas why? Thx

Most likely because you nicked a vein and blood under pressure mixed with gear. Also inject slowly (30 secs to a minute) and wait 10 seconds after full plunger depression before withdrawing needle. This will allow gear to be absorbed slowly in muscle and waiting will allow any pressure at depot to dissapate.

Rereading your post I see you were midway through when this occured, you probably have some scar tissue or a sterile abbcess, you should avoid this spot for a few weeks also always rotate sites at least use glutes, delts, thighs.
