T Nation


Ok, I know this is a stupid question but I was wandering… 4-AD is converted to T via an enzyme in the liver, then how is the 4-AD converted if it skips the liver?

Everything goes through the liver it’s just a matter time.Injectables and topicals get a first bypass since the liver is intimately related to the digestive system.

Won’t the 4-AD still be chopped up in the liver whether you take it in oral form or another route?

Also, the conversion enzyme is found in the blood apparently (since incubating in blood
results in conversion) and is distributed throughout the body. Even so there is not a lot of the enzyme, so the amount of conversion is fundamentally limited.
