Strange stomach noises aren't listed as a side effect of Var in any of the literature I've been able to find That's why I asked a similar question in post a few months ago.
Nausea and vomiting are normally listed. Most orals AAS have the following listed as sides (though this is a very general list):
Nausea, vomiting, loss of appetite, diarrhea, trouble sleeping or excitation (may occur the first several days as your body adjusts to the medication), acne, yellowing of the skin or mood changes. Males before puberty may experience increases in penis size, frequency of erections, and hair growth. After puberty, males may experience loss of scalp hair, breast tenderness or swelling, trouble urinating, changes in sex drive. May cause serious, sometimes life-threatening liver problems including liver failure, liver cysts and liver tumors.
Sound like shit load of fun doesn't it , but I still think it's the best oral I've tried.
