tbol by itself is fine, 5 weeks is way to short you dont feel it usually till mid way through week 3, but when you do you do. Weight gets lighter and it puts on some good clean dry mass. Keeps you pretty pumped all the time too. But on the other hand tbol increases appetite ALOTTT you will want to eat everything all the time so its not ideal if your trying to keep your bf down, unless you run some kind of appetite supprs
