this is my first msg tho im a long time reader...
well lets get stright to it.
just got my first injection 2 days ago (sus 250), and iv got the pain stright after and still today. but what really "scares" me is that i have flu like feeling and a lil fever, because its only been 2 days i dont think it an infection but what do u think?!?!?!
First two cycles I did I got "test flu," whatever the hell it is. I imagine it is your body reacting negatively to the foreign substance you are introducing into it, and using the fever as a means of fighting off this imaginary foe. First time I got it it was really bad, like I was shaking like crazy, had whole-body muscle-soreness, fever, chills, the works.
I had to go to bed early (which I never do) and cover myself up with about three blankets. Next day, however, I was pretty much fine, but I would get a little bit of it toward the end of the next few evenings, though incrementally less bad. It completely disappeared after about a week. Then I gave myself food poisoning, but that's a different story!
From the limited amount of information you give this is what it sounds like to me. If things don't change, of course, you will need to take measures to take care of yourself.
Infection would be specific to the injection site,ie" swelling, redness, puss, bruising etc... some bodies just react differently to foreign compounds regardless of quality, purity of the compound injected.
