Test E Stack

I need to know whether to save this Turanabol (got 200) till after the enanthate is long gone (day 84-100 when my test will be about 75mg) after 70 day cycle of fourth day TestE or stack it with the 500 Test E and 40mg Winni I’ve been takin since 3rd week of Test E shots. Got 16 more days (4 shots) on the TestE then my T start to levels drop down under desireable levels to about 70 after 20 or so days (i think after using the PCT calc).

Problem is, I don’t know much about turanabol or what its strong points are. (cut or bulk, maintain, E-block, DHT-block…ect…?) Gimme a hand??
