There is limited information available on the pharmacokinetics of oxymetholone.  It appears to be well-absorbed with oral administration .  Oxymetholone has very low affinity for human serum sex hormone-binding globulin (SHBG), less than 5% of that of testosterone and less than 1% of that of DHT.  The drug is metabolized in the liver by oxidation at the C2 position, reduction at the C3 position, hydroxylation at the C17 position, and conjugation .   The C2 hydroxymethylene group of oxymetholone can be cleaved to form mestanolone (17α-methyl-DHT), which may contribute to the effects of oxymetholone.  The elimination half-life of oxymetholone is unknown.  Oxymetholone and its metabolites are eliminated in the urine .  
The use of anabolic steroids will suppress natural testosterone. The rate of suppression is dependent on the steroid in question, but in the case of Oxymetholone it is enough to warrant the use of exogenous testosterone. This will actually hold true with most anabolic steroids. Those who supplement with Anadrol and forgo exogenous testosterone therapy will fall into a low testosterone condition. Not only is this a condition that comes with numerous bothersome symptoms, it is an extremely unhealthy state. The form of testosterone you choose when using Anadrol is of no consequence, however, you should ensure you are applying enough to provide what the body needs.
Once the use of Anadrol and all anabolic steroids has come to an end and all the exogenous hormones have cleared your system natural testosterone production will begin again. This is assuming there was no prior existing low level state. It also assumes no damage was done to the HPTA during supplementation due to improper practices. While natural testosterone production will begin again on its own, it will not be fast. It is generally recommended that the individual begin a Post Cycle Therapy (PCT) treatment plan following anabolic steroid use . This will encourage natural testosterone production and speed the healing process up. It will not automatically return you to your previous natural high level on its own; that will take some time. However, it will ensure you have enough testosterone in your body to function properly while your levels continue to naturally rise.
