@harryboy7 I have had the same experience with the Tymlos manufacturer -- cannot get straight answers to my questions. In particular I question their standard dose amount of 80 mcg regardless of the recipient's body weight. I am 105 lbs and 5'5". Should I get the same dose amount as a 150 lb person? I think not. Even the lab rats in their clinical tests responded adversely to higher doses, with the male rats receiving the highest dose over 2 years developing bone cancer at a rate of 87%. I want to cut my dose to 60 or 70 mcg and cannot get any info as to potential outcome. Manufacturer is not helpful in this regard. After 3 months I still have side effects, especially dizziness.
