Comparison of the relative potency of PO vs. SC dosing of TB on LABC weights in the Hershberger assay. SC dosing with TB was approximately 100-fold more effective in increasing LABC weight than PO TB. Relative potency estimate was based on the magnitude of the differences between the dose response curves where each route of exposure produced approximately equivalent effects.

could someone explain-- does this study claim that the reaction of oral TBA is 100% less effective than oral with equal dosages?or you get a more anabolic reaction thru inject reguardless?---trying to figure ,if someone had a bad experence[progestinal fat gain]with TBA oral [12 pd] would it be any different with inject?
