From my experience your really going to want to increase the epi dosage and length of cycle. Havoc / Epistane does not really kick in until week 3, so your selling yourself short by only having 1 week to go. Increase your cycle to 6 weeks.
Here is a cycle layout for you -
Dosage per week - 40mg/40/40/60/60/60
I usually run 30mg for couple days the bump to 40mg
This is the most effective pct I have used for Epistane cycles.
Clomid - 25mg/25/25/25
Unleashed ( from protein factory or **** )
Post cycle ( from protein factory or **** )
Formestane product ( either Formeron or Formastanzol )
I've used nolva before and recovered ok, but this set up had me feeling the best.
I tried a different PCT set up for my last cycle and didn't recover nearly as quick as I did with the one I set out. Will return to this setup for future cycles myself.
All support supps are necessary and great to see you have them.
Epistane / Havoc is an excellent cycle - great gains with little to no sides.
