I was on bioidentical hormone creams through another doctor and thought I was doing fine -- my blood tests looked good. Dr. Heather told me about the advantages of drops and suggested I try them instead. She used a saliva test instead, that indicated my hormone levels were WAY out of balance. With adjustments in dosage and a switch to drops, I have more energy, Iíve lost weight and my sex drive has returned. Yippee!
