im currently doing a 1-test & 4ad cycle, im comming up to the 3 out of 6 week mark....and i have 4 left over amps of test enanthate im thinking of using, so by the time the 1-test and 4ad is up, the test will be in my system, so after the 2 additional weeks of test could i use tribulus and 6 oxo for pct or does it have to be nolva?

thanks
