"The real absobrtion rate for Trans Dermal is eighty percent not twenty to thirty percent"
REGULATOR, if you can give me one study that shows a formulation which gives 80% recovery of an applied hormone, I would be a happy man. I'd have that shit made up and would be selling it right now. Look up the research...transdermals have a tough time fighting their way through the stratum corneum.
"Okay let's get this straight here....is it because of the ester or the parent compound that makes it orally available? Is this why Trenbolone acetate is purported to be orally active?"
The ester is what gives an INJECTABLE drug its half-life. It modifies the drug's potential to remain in it's vehicle (oil or water), or to exit the vehicle and enter the tissues/blood.
Chemical modification of the base drug is what gives the majority steroids protection from hepatic metabolism. Most are 17-alpha alkylated, some are 1-alkylated. The exception is Andriol (testosterone undecanoate). This drug is orally active, due to its highly lipophilic ester, which partitions itself in chylomicrons and is taken up by the lymphatic system. Unfortunately, it tends to remain in the chylomicrons, thus giving very low release and effects.
