Adrafinil is a prodrug for modafinil that's entirely liver-dependent; there's not a lot of published safety data, but it would not be advisable to use it as a daily supplement. Every other day for a few months with a good break afterwards, perhaps, but no more than that. That covers razor edge and straight adrafinil.
Ampitropin appears to contain picamilon, which is a niacin-bound GABA that penetrates the BBB. You really don't want those receptors to adapt to a consistent dose, so much like phenibut, it'd be a good idea to limit use to no more than a few times per week.
