So the article stated that the faster the liquid was injected the more the muscle would tear. They talked about the overall size of the scar being the issue. It makes sense especially if your shooting GSO. Wish I could I find it again. For people who do a few cycles, I doubt there is a huge concern. However, being on trt I’m try to prevent it as much as possible. My quads are getting scar tissue and it sucks balls. I love quads. I have about 3 spots that never give me a issue the size of a quarter. Trying to hold on to them.I doubt it impacts scare tissue as that’s usually from the physical trauma of the pin, but slower injection should limit some PIP as it allows oils to disperse. I don’t think anything but a steady hand and an appropriately sized needle REALLY makes a difference though.
