Help! long lasting Soreness After Tren E injection

So I pinned Tren E and Test C on Tuesday, it didn’t hurt immediately but the next day my glute was so sore and its now Friday and its still pretty sore. There is no bulge or bruising, not even redness. I’ve had bad gear in the past from a different brewery of course and it would leave a massive lump and you couldn’t even sit down. This is not that bad, There’s no lump. Is my gear bad or could it be user error?
