I wouldn't. EQ sometimes takes up to a solid 5 weeks before you even "feel" anything. Not to mention PCT. You have to give it 3 weeks before jumping into PCT. This would not bode well considering you're using var and prop (PCT begins the next day).
I'd say.....Prop/Var for 8 weeks at adequate doses would rock! Good luck.
YES! It is definitely worth it. The last cycle I ever ran was a 4 weeker with EQ as the base for the last 2 weeks. Worked very well to solidify the mass gains made from the previous Anadrol and Sust androgens over the first couple of weeks.
I would say it is worth it if you do not go lower than 400mg/week for 8 weeks ... preferably front-loading the first week at 800mg to get blood levels higher sooner....
