First Primo Run

Hey everyone, I just got my Primo and started looking into it a couple weeks ago. Plan is 400–500 mg Primo per week with 300 mg Test for 12 weeks. Right now I’m on Test only, 300 mg/week, injecting daily. I know sub-Q gets a lot of flak here, but daily sub-Q Test feels great to me. I’ve never done IM injections, so I was thinking about doing the Primo sub-Q too. I saw a thread where most people told the guy not to do that. What’s the issue with doing more frequent smaller shots versus fewer bigger ones? I feel like I’ll get flamed for asking, but this is my main worry right now and I don’t have anyone else to ask.
