AZT: Unsafe at any Dose?

Muscle Disorders (including Heart) Associated with AZT

AZT causes muscle damage, which often shows up as muscle wasting or pain. It is believed that this is largely through damage to mitochondria, the energy regulating organelles in every animal cell. AZT may interfere with the replication of mitochondria (which have their own DNA) or with their supply of phosphates, the energy currency of cells.
