Perhaps there is a practical reason Alcor doesn't offer it, maybe it's too expensive, I could be wrong but I don't see why it should cost more than cryonics. <br>
<br>At any rate I'd still like to know what Alcor's official position on chemopreservation is.<br><br> John K Clark<br><br> <br></div></div>
