Hi there,

Just wondering if anyone has ever tried a substance called Hypoxanthine Riboside. It is a mixture of Inosine, B12, and other amino acids. Cant remember the trade names, but it is an injectable. Ben Jonson and other elite sprinters used it on top of all their other gear to enhance recovery, and CNS activation. I have used inosine tabs on their own along with B12 shots, and they do work ok, but injectable form is obviously better.

If anyone has used it, can you give me some trade names u used, its effectiveness, and whether it is a controlled/prohibited substance.
