Same here, I'm fairly new to injecting my own ass. However, I am a nurse, so I'm fairly confident in my injection technique and maintaining reasonable sterility.
Still kinda sore, but nothing debilitating. I wouldn't train leg day, but I worked a shift last night, and I'm at work again. Considering calling out for tomorrow night since I have to inject again in the morning lol.
All in all, I think it just boils down to me using a longer needle and doubling my injection volume. I'm not overly concerned, just wondering if others are having similar experiences with the primo.
