LiquiNolv question

I just bought LiquiNolv 20mg/ml- 60ml. The only problem is I don't really know how much i'll need to begin my cycle. I was planning on taking the Nolva throughout the entire cycle with 10 - 20 mg a day. I was just wondering how many bottles i'd have to order to do a 10 week cycle and then have 5 more weeks for my pct? And i heard that you don't have to take Nolva unless signs of gyno act up, if so could i start taking the Nolva at week 5 just to be sure and run it through the rest of my cycle? My cycle is test e 250 twice a week for 10 weeks and d-bol 25mg for the first 5 weeks?

well jus do a lil addition bro if you take 20mg ed and you have 60ml you can take it for 60days until you dont have any more.. factor in the days of pct and there you have it

tanks a lot...i couldn't do the math lol
