im currently finishing up my fina/ sust cycle i did 500mgs for 7 weeks except for week 1 which i did 750mgs , i started fina in week 4 i started seeing changes at the end of week 3 , i took 250 mgs every 3 days. strength gains weren't that big but it definantly helps you gain size and with the combonation of fina it really helps you change your body. But make sure you have post cycle recovery set up, because your going to lose a lot of water when your off.
