Hi Julie and welcome to the board :wave:. That is a good question, but i don't think you could unless you went to Europe, got a script from a dr. and had it filled there. The strontium citrate we can buy here in the US is basically the same at the Protelos without the added renalte salt, that makes it patentable. I've been taking strontium citrate for almost 3 years and did show improvements on my last DEXA, which was only after taking it for 9 months. I'm due for another this coming summer. Take care...phyllis
