I would imagine this would work well with BRIDGE but not as a substitute.
BRIDGE is more than libido and test elevation. I admit, this TS17 would be a stronger T booster -- it has the active ingredient of phytoserms (though I don't know how much) but BRIDGE addresses several aspects of enhancement, most notably an increase in blood volume and anti catabolism.
I think a stack of the two would be pretty incredible in between cycles
