im currently taking test enth..ive used several times before and sure we ve all had those painful knots at injection sites before, but this is like no other...we ve used this same gear before with no problem, but me and my buddy are both using (only 1cc 300mg a wk) and both of us can barely walk its so bad.....could it just have something to do with the way this batch was mixed or what? any info would be great....thanks
