Injection sites, need help

[Brian23]

I am 5'11 and weigh 133lbs and trying to gain weight. I usually give myself 4-6 shots a day(with solarstar pens and smallest needle possible) and I keep hitting veins or getting into muscle tissue. I am very lean with limited places to inject. Sometimes when I inject into the abdomen area, Its like my skin bubbles up. With me being so lean, I am finding it harder to find places to inject. Can I inject in butt cheeks?, is this a prime place to inject, what are some problems that may be caused by injecting in butt? Also, what are the problems with hitting veins or injecting into muscle tissue, I bruised really good after hitting a vein, but what else? I need help

A lot of people inject into the upper butt area, right where the tops of the pockets would be in your jeans. Some also like the thighs.

I'd definitely worry about the actual butt cheek, since if you're lean it's probably all muscle at the surface, instead of fat.

Another thing you can try is pinching your belly area, find a good fold of fat, and inject at an angle. This way you can be sure to get the fat and not muscle...

I'm not thin, so I don't have your problem... Once I get all this weight off, I hope to have your problem! :D
