No results for alchemy.
Fortunately, you only need a few potions to be successful in the game.
I do agree that some potions like the increased damage ones should scale with level. However, I am sure they are being careful with Alchemy as in previous TES games, Alchemy was the best path to Godhood through various exploits and techniques. I don't think anyone wants the tide of a keep battle turned on the efficacy of a brewed potion in PvP.
