remember that most sust will have the prop in it and the long ester, so its up to you if you can find prop and run it for 2 wks after your last pin of sust if you choose to do so.
tapering you dont have to, maybe some do but i dont think its needed, keep contant amount throughout cycle.
store in a dark closet, dont put in fridge.
try and get hcg if you can, your not doing a CRAZY cycle but i think it should be used during just to be safe, better safe than sorry
