I just finished my second bottle of Derm LV yesterday and started SA LV, and I can tell you from my experience that the LV is not crap. My strength has increased and body comp was real good. I never ran the topical Derm, so I honestly can't compare the two, but I have done the SA topical and it was OK for me in terms of what it was supposed to do. Bottom line is I think you will enjoy the Derm LV.
