1) don't get your hopes up too much for tbol. as powerhouse says, good strength gain, smallishmass increase. if you are hoping for dbol but without the bloat then you will be disapponted
2) you say you are doing the cycle because "gym has been a bit slow" and you are waiting to do our first "proper" cycle. my opinion is forget about the tbol, sort your training and diet and do your test cycle. Use the tbol then as a kickstart if you like.
