Rash 24hr after injection

I have been on tirz for 6 weeks now, but the 1st kind I took was from AltRx and has a b12 mixed in with it. Had no issues.

I just started ordering from MintMed and they use Hallandale, so yesterday was my 1st dose of that "brand". All was good until this afternoon (24hr later) I started itching on my injection site and when I realize that's what was itching I looked at the area had a red spot but not really a welt. I put some hydrocortisone cream on it and it's been fine but still is red.

I was just wondering if this was normal for other Hallandale users?

I have a 3 month supply so it would be shitty if I react to something in Hallandale and can't use it 😅
