I've done a quick 30 days on fina & then switched to fina/suspension for another 30 & swelled up. Tren by itself depending on your caloric intake will definitely bulk you up but at the same time harden you out. I got great strength increases, killer pumps and brought out alot of definition. The first week good luck getting a decent nights rest cause the night sweats will have you waking up every few hours...at least for me. What can I say 75mg ed is good sh*t, you'll have some good results if your diet is in check, add a little test and see how much better things get!!
