Hi docs, would i grow mass if my testosterone increases?

Maybe (not) . . .: Many variables to consider. How high is your current testosterone level? If it's already "normal", more won't necessarily increase "mass". Speaking of which, what "mass" are you hoping to grow? Assuming muscle, you also need to accompany your increased testosterone w/adequate nutrition as well as exercise. Bumping up your T then sitting in your recliner won't do anything for body composition.
