Ok i injected test 500 for the first time on the 17th and now four days later my leg is still very tight and i just noticed a larg lump around the injection site. I injected into my right leg and didnt notice anything until the next day. The amount injected was 1/2 a cc of test 500 so 250 mg. The tightness and pain in my quad has just gotten worse and seems to hav decreased slightly just today. Although im still afraid because as i said theres a large lump and my muscle is still very tight. Any insight would be awsome cuz im freaking out here.
