Alpha lipoic acid looks awesome for its liver protecting qualities, but also for its insulin immitating properties. It apparently kicks arse for protein and carb uptake and is the best supp. for creatine.
However, here in Australia, the cheapest I could find was 90x200mg caps for AU$90. Damn expensive, but apparently you have to pay the extra to get the oil caps, because it oxidises so readily that it is worth shit in dry powder form.
Just a bit of info I picked up.
