I think at your weight and being 3 cycles deep u should learn how to eat and grow without steroids first. With those 3 cycles you've done you should be alot bigger brother. Not being a dick either just being honest.
I agree with ECKS...you can definitely get above 168 naturally if you eat more being off 18 months is a good thing. I didn't jump on juice until I already had years of lifting/dieting and weighed 185-190 and I wish I had waited even longer...so be patient. But other than that the cycle set up looks good.
