I got achy feeling and felt like my head would spinn when i turned it. IT felt exacly like a flu coming on. It hit me the first few days after a prop shot. It would last for the day. It finaly stopped. Just this past week I had a sore throut and body aches it went away. That was a bad cold. Then a few days later. I started shivering with chills horibble body aches, head spinning but no sore through, no runny nose, no coughing no sneezing. It happend two days after switching too a new ugl. I had some left over amoxacilian and took it and it went away in like two days. I was so eiger to pinn this new ugl that I reused one of my pinns. I thought I had steralized it but apparently not. I have since bought more pinns..lol lesson learned.

hmm,,i only got the test flu with some test like sususton..but the cold symptoms constist with muscle aches and sorenes like when you get the first stage of the flu,last around 1-3 days and gone...the sore throat,runny nose tells me you might have caught the real flu or have a small virus...seems to me the immune systems is affected alittle bit by fogein substance like test,etc entering the body at first with new cycles until you get used to it..everbody is different bro,,this is what happens to me though sometimes.

Yeah bro it can happen. All my cycles that i have done in past all consisted of st8 up sus
Couple times i felt like that for day or so it goes away trust me even one time i had a fever all night its your body reacting to what your putting in it! Relax bro youll be fine. You dont have the normal flu. When it passes youll feel great!
Seems like it happens alot with sus.

could be just the flu. Here's something i found on the subject

a natural defense mechanism - to the sudden increase in exogenous hormone levels. Its the body's way of trying to "flush" out the foreign entity it perceives is there (just as it does w/ a flu virus). There has also been some connection between high BA content and immune response. think the combination of sudden increased hormone levels and a foreign substance being injected into the muscle can cause these symptoms. Some people are sensitive, some arent. Certain people don’t experience it at all and some might just get mild chills (low grade fever) or a runny nose for a few days and not even take much note of it.

etiocholanolone represents only about 20% of the metabolites of testosterone in people. Maybe folks who experience this reaction to testosteone have particularly high levels of 17 beta hydroxysteroid dehydrogenase, the enzyme that converts testosterone into etiocholanolone. Or an isoform of the enzyme that makes the conversion more efficient.

Etiocholanolone is believed to produce fever and flu-like aches and pains because it induces the systemic release of Interleukin-1, a powerful proinflammatory cytokine:
