My search has not been fruitful in finding in the US companies that sell bioactive collagen peptides with FORTIBONE that includes the registered trade mark as used by the study. Can anyone share where to buy safely in the US? What companies produce this 5 gram a day powder that is not cost prohibited ($30/monthly). It seems there are horror stories about hip fractures, etc on some of these drugs so have been on HRT for about 9 months, doing strength training, and hope to find this suppliment before my next scan. I will report back after the scan.
