Stacking LDG (12WKS) & MK-677 (12MOS) soon adding RAD-140 & GW 50 (12WKS) Do I need an on cycle PCT? I do have a bottle each of :LiquiAro & LiquiNol for PCT. Also have been using 1/2 dropper of MK-677, and a full dropper of LDG. A member mentioned to use a full dropper of MK to get the 25mg, but what is odd is both droppers are the same size, and liquid levels are the same in both bottles ,in spite that I,ve been pulling out only 1/2 dropper from the MK? Any constructive input is appreciated.
