30% Bic , 30% Derm , 30% Oxy , 10% Tricord .
I fill up the reagent tank and leave it in medbay.

This gives the most amount of heals per sip.
Oxy reduces the slowdown from fractures more than Tram. Oxy's metabolism is also the same as the Bic and Derm, so you drink to heal until you don't need it anymore.

Tricord pads out the remaining 100u in the reagent tank. It's medicinal sawdust.
