Hey guys...I'm one week into a QV Test E(500mg/wk) and EQ(400mg/wk) cycle and am getting tightness in my chest within minutes after injecting.It lasts around 3 hrs. I'm 31 yrs old in good shape, low BP(even during the tightness), and low cholesterol. I always aspirate so I know I didn't hit a vein.I've used this EQ in the past with no problems but this is my first time with QV test...anyone ever experience this and also anybody know what QV uses to cut their enanthate with. I'll probabally go see a doc but it's hard to find one who will give you an unbiased opinion. Thanks in advance
