Description:

WARNING: This product is for research use only, not for human or veterinary use.

Dextrothyroxine (trade name Choloxin) saw research as an cholesterol-lowering drug but was pulled due to cardiac side-effects. It also increases hepatic lipase which in turn improves utilization of triglycerides, improving apolipoprotein E cholesterol particles. (Source: https://en.wikipedia.org/wiki/Dextrothyroxine).
