Yea, that's why I was confused when you said they weren't. There is an actual item with the name reusable in it that isn't BoP by the looks, and may as well not have a biochem requirement. But the exotech would be superior for min/max reasons.

Well if the Rakata isn't reusable then why do both website databases have the tag "this marvel of biochemical engineering is not consumed on use?"

Yea, looking at Torhead and Darthhater there is also purple quality non-BoP reusable stims/adrenals/medpacs but their stats are a decent margin lower. Stim's difference looks to be 24 mainstat/ 9 secondary stat lower from the Exotech counterpart which isn't resuable. Adrenals are 85 stat difference between the reusable and exotech. And Medpacs heal is significantly lower and also doesn't have a hot component.

The best adrenal/stim/medpac is Rakata, which is BoP for Biochem. The tradeable one looks to be Exotech which is slightly lower in stats vs Rakata. It would also be silly if the best BoP consumables that Biochems can make weren't reusable.
