Were you taking any other AAS while on the Fina? Alot of guys on here dont recomend taking the fina alone. If you did get BT's from the Fina, it's more likely from the progesterone... There's alot of speculation on whether or not winny is a good p.g. blocker or not, but my last cycle, I used Fina at 75 ED, Winny at 50 Ed and Cyp at 500 Ew. PM me if you have any questions bro and I'll help as much as I can....in the mean time, bump up for more opinions.
