Small lump at injection site?

[PistolPete33]

This is fairly new. I have a small lump that is quite hard at my injection site. I injected 1ml into my left glute on Sunday and today is Tuesday. The lump is fairly hard but not hot to the touch or anything like that. I'm not concerned that it's infected because I'm ultra cautious when I inject and super clean when I do. I've also been on TRT for over a year so I'm not necessarily a newb with injecting. I'm thinking it's just that the oil hasn't been absorbed yet or it somehow hardened while be broken down? Not really sure just wanted to see what the vets here think it might be. I'm not overly concerned with it but just want to make sure if there is any chance of an issue I would rather take care of it right away than wait.

How many times have you pinned that spot over the last 16 weeks?

Once per week. I rotate between 6 spots.
