It has been a long time since forteo and I no longer have the records. I do know that I had very minor gains. I had had about a year on alendronate before seeing an endocrinologist then resumed after 2 years of forteo. I don't think that anyone knew them that taking it after a bisphosphonate would negate some of forteo's bone building properties. That is my guess at least. I'm sorry that I can't offer better information.
