Try reading the Steroid Newbie Thread. Because you obviously know little to nothing about AAS use. First off, a 5 week cycle is nothing, you might gain a little, but certainly not enough to justify the cost for such a drug. Secondly, why the hell would you take 1 week off before starting PCT?
It isn't an ester that stays active for a week, its an oral 17aa steroid that has a half-life of about 5-7 hours. That means, 5-7 hours after your last dosage you should begin pct. And IMO, a T-bol only cycle is a waste of time. Why wouldn't you want to run a 10-12 week test cycle?
Tbols half life is 17 hours, you could gain about 12 lbs in 5 weeks if your diet is right. A tbol only cycle is only a waste of time if he wants more gains than this. Why take test for 12 weeks to gain 20+ lbs and a nice does of acne to go with it if he's only after 10 or so lbs ??
What would be wrong with 20mg/day for 7 weeks, then evaluate? If this produces no results, try (after a couple months off) 40 mg/day, same time frame. If you get good results at 20, you save a whole lot of folding green.
I know that 20 is a low dose but is it so low that you'd get NO results whatever? I wouldn't mind putting on 6 or 7 lbs of lean-and-clean three times per year.
Yes, it is always dependent upon the diet. It definitely isn't a powerful mass builder, but I don't think most people consider putting on 10lbs as "powerful mass." I would say you will gain 5lbs just from the tbol assuming your diet remains the same, maybe a little more.
