I'm about done with this cycle i'm on, and here for the past few weeks I cant hardly get the needle to go in, I rotate my injections and i've tried different gauges of needles and brands, but its like I'm pushing the needle to the point that its going to break before it will finally go through the skin and into the muscle. has anyone else experienced this before. this makes the second time this has happened, I dont know if its where my skin is firmer or muscles are harder or what,
