correcting muscle symetry

[JuicedMoose1]

can anyone help me out with trying to correct this unbalanced symetry in my biceps. My left bicep has more of a cut and has a higher peak than my left. I've tried a few tecqniques such as extra reps with the right arm and tweaking dumbell curls to try to fix it but no luck. I have spot injected test suspension into both of my biceps in previous cycles before, wondering if this has anything to do with it.

It would help if you posted pictures. Either here or in the member picture section.
