40mg of tbol & 40mg of var stacked together is fine, and would be a nice cycle for 6 weeks.
but the winni is dosed too low, as 20mg isn't going to bring much to the table, most if not all effects will be seen from the tbol/var.
but if one were to take it for 6 weeks, it wouldn't be that bad, certainly not as bad as sd/pp for 4 weeks.
it's just when someone wants to take two or more of those tabs, that it would be a problem.
