ok had a problem with tren last time i have used it.Felt very strong at beginning but by the end of week 4 i felt like i had too much shbg because of high androgenic ratio of tren and if i remember correctly shbg binds to the steroid and it "cancel" the effect of it.So i was thinking using letro but im not sure it lowers down shbg or could use proviron wich i know dose.What do you think.........
