Yes, definitely chew the anavar tabs. I do not think you will have a problem with sex drive with taking eq/anavar. Recently I was doing eq/anavar and had no problem with sex drive. The problem started with I threw in fina for the last 7 weeks of it. I had no sex drive. You should be okay, but some people are different. Since you have the sust, why dont you try something like this
Weeks 1-10 eq @600mg/week
Weeks 1-10 sust @600mg/week
Weeks 1-6 anavar @50mg/day
If you can, pick up some arimidex or liquidex and run it at .25mg/day if you are going to use the sust. If you do not use the sust, you will not need either or. Best of luck whatever you decide to do. Keep us updated with your results.
