Are you sure you want to run ten weeks?? From all the posts and articles I have read the max time on Fina is 8 Weeks.
Your call...But here's the math;
2000 g/cart divide this number by the # of ml's your going to need and presto chango there you go...
Example: 10 weeks= 70 days at 1/2 ml per day= 35 ml's total
if you want 75mg/ed you'll need 150mg/ml so...
150*35=5,250 mg tren or 5 carts + 13 pellets from your 6th cart will give you 5260mg....
