These chylomicra are absorbed into the lymphatic circulation, which by passes the liver. muscle fitness Steroids for women. If you make a steroid lipophilic enough by altering its structure, then it too will incorportate into chylomicra and absorb into the lymphatic system. Once in the lymphatic system it can cross over into the general blood circulation, making it there without being subjected to the massive metabolic breakdown in the liver. Scientists have found that by adding lipophilic side chains to steroids, they will to some extent be absorbed into the lymphatic system. muscle fitness Steroid-inhale+rs. If the side chain is linked on in such a way that it can hydrolyze (break apart) easily after being absorbed, the steroid is essentially rendered orally active. Two side chains that have been utilized to increase the oral bioavailability of steroids through increased lymphatic absorption are long chain alkyl ester groups, such as is seen with testosterone undecanoate (andriol), and enyl ether groups, such as is seen with quinbolone (anabolicum vaster). The term "orally active" is of course a relative term. muscle fitness Steroid-cycles. Lipophilically modified steroids are more orally active than the free parent steroids, however, they are no where near as active as the 17alpha-alkylated steroids. Testosterone undecanoate (TU) is probably the most commonly known lipophilically modified androgen, and it is not considered a very potent compound (its recommended daily dosage is about 240mg). In fact, one study found the oral administration of testosterone undecanoate led only to an absolute testosterone bioavailability of 6. 83 +/- 3. 32%. That is very slight, especially considering the fact that in the same study they found the bioavailability of straight testosterone to be 3. 56 +/- 2. 45% (Eur J Drug Metab Pharmacokinet 1986 Apr-Jun;11(2):145-9). That means TU is just a little less than twice as orally active as free testosterone, which is unimpressive to say the least. The other problem with lipophilic steroid preparations is the high variability in absorption from one person to another. In other words, one guy might absorb the stuff very well while the other guy might absorb very little.
