Either works fine man. If you're concerned about SHBG upregulation, simply taper off your dosing for the last week or two and you should be fine. Even extending the 'cycle' length out to 9-10wks for this purpose would be ok - you wouldn't see much noticeable effect in those last weeks, but you'd 'restore balance' faster. But even that is NOT absolutely necessary; any SHBG increase should return to basal levels fairly fast after cessation.
The idea of 5on/2off is popular with L-Dopa products, and there is some validity to the idea, so you could do Endosurge 5on/2off, but I wouldn't do DAA or Erase like that.
