if you have 8 weeks left then probably masteron prop would be better, enanthate is always better on cycles 12 weeks or longer sure it can be used in 6 week cycle but it takes time to build up and build down for 2 weeks and those 2 weeks are taking away from your pct. as for dosage i would say 300-400mg a week is great for lowering SBGH and thus increasing the free active testosterone and for keeping the water down somewhat and giving you some lean gains.
