t-bol is a potent derivitive of d-bol. it doesnt have any androgenic activity, which means you will not get the water retention that you would from d-bol. excellent during lean mass or cutting phases.
I've been doing alot of reading about T-Bol, and those who have taken only OT usually show between 6-12 pounds on a bulking cycle. Usually these have been 1st cycles however. Alot of people use it to cut too. Most people say it is kind of like a poor man's Anavar, although it isn't quite as good of cutter as Anavar.
if you double or triple the mgs turanabol can be compared to dbol... but you don't get a bloat on tbol so its quite good choice for those who don't want to get moonface... I did tdol last spring and liked the shit... I don't say t-dol is great substitution of a d-bol which I actually like most of all ... its just another drug and its great in my opinion...
