a couple things. aspirating and not seeing blood doesn't mean you didn't hit a vein, and also you can nick a vein on the way out as well. so aspirating isn't even necessary.. i never aspirate and i've done hundreds of injections. if you insist on aspirating thats your business, but hard to do that when you are injecting 2-3ml using a 3ml syringe
as for hitting blood being a problem.. unless you are injecting tren its not a big deal.. with tren if you hit a vein you run a good chance of getting tren cough which sucks. this is why its a bad idea to inject tren in your quads or hips where there are many hidden veins you can hit.
also the dude that died from hitting a vein probably weighed 300 pounds with 30% body fat and shouldn't of been juicing to begin with.. or he probably died from something else and it got blamed on steroids. sadly many roid users are also druggies and use a million other things and then make everyone look bad. or maybe he injected directly into a vein like a moron not knowing he is supposed to go IM.
bottom line is no biggie but don't make a habit of hitting veins and you have a better chance of getting eaten by a shark then dieing from a simple IM injection.. you should learn to pin your delts and pecs which are two areas that even a dummy can pin without hitting blood. quads and hips are tough,
you run a good risk of getting abscesses in your quads as well if you go in at a bad angle... hard to miss when you hit the delts and pecs
.. cant speak for glutes as i haven't pinned in there in forever, no way with my wide shoulders can i manage to pin there, much less aspirate.. but if you can pin the right spot on the glutes its a very easy injection...
