This is my second cycle and my question is how come the next day after an injection I always have a knot where I injected at? I just did my glute injection yesturday and today there is a big knot and it is very sore. It hurts to lay down on it. It is not red or hot like an infection just a knot and I get it every time. Is this common? I injected testosterone enanthate at 1cc which is 300mg's with a 23 1.5 inch pin.
