If by referring to a var run you’re talking about anavar, just get some test e or test cyp and pin. Anavar is a C-17aa oral steroid which is already hard on your organs and you would have to dose the **** out of any currently available oral PH to use as a base. I mean to use 4-Andro or Epi-Andro as a base you would have to dose 1000mg a day to actually benefit from it. Running something like dermacrone could work but you’ll have to get lots of blood work done to get the dosage amount dialed in. Or run a long ester test, test e or cyp, between 350-500mgs a week split between two injections. Regardless of your choice you’ll need a cycle support with milk thistle, Tudca, and NAC if you’re taking anavar along with an aromatase inhibitor like aromasin or srimidex to combat estrogen related sides which could happen when using a test base.
