Anabolic steroids differ in their characteristics, which means there are steroids that are only suitable for specific uses. For instance, Trenbolone is not recommended for bulking but it is an outstanding fat burner. This makes it perfect for a lean mass cycle or a cutting cycle. Always take the side effects of a particular compound into consideration whenever you plan a stack. Do not combine anabolic steroids that show similar side effects. For example, never combine Anapolon and Dianabol because they are already quite toxic and if you combine them, the toxicity will increase exponentially and cause serious damage to your body.
All anabolic steroids suppress natural testosterone production. However, the rate of suppression often varies greatly from one steroid to the next. Although it does suppress natural testosterone production, Primobolan’s rate of suppression is much less dramatic than many anabolic steroids. In a therapeutic plan, it is actually possible to keep the total rate of suppression below 50%. This could be low enough to keep some from falling into a low level condition despite the reduction. However, performance level doses will be another story. Dramatic suppression is all but assured with such doses making the inclusion of exogenous testosterone extremely important. Men who do not include exogenous testosterone will more than likely fall into a low testosterone condition. Not only does this carry numerous possible bothersome symptoms, it is extremely unhealthy. Women, despite needing testosterone will not have a need for exogenous therapy when using Primobolan.
Once the use of Primo and all anabolic steroids has come to an end, natural testosterone production will begin again. You will find this is one of the easiest steroids to recover from when it comes to testosterone production. Most men are encouraged to implement a Post Cycle Therapy (PCT) plan once use is discontinued. This will speed the recovery process up. It will, however, not return you to normal on its own. This will still take time. However, a PCT plan will ensure you have enough testosterone for proper bodily function while your levels continue to naturally rise. Those who do not implement a PCT plan, while they may recover it will take far longer. There’s really no reason to forgo the PCT process if you’re going to be off cycle for any decent length of time.
An important note on natural testosterone recovery. Natural recovery assumes no prior low testosterone condition existed. It also assumes severe damage was not done to the Hypothalamic-Pituitary-Testicular-Axis (HPTA) through improper steroidal supplementation practices.
The liver receives a dual blood supply from the hepatic portal vein and hepatic arteries . The hepatic portal vein delivers approximately 75% of the liver's blood supply, and carries venous blood drained from the spleen , gastrointestinal tract , and its associated organs. The hepatic arteries supply arterial blood to the liver, accounting for the remaining quarter of its blood flow . Oxygen is provided from both sources; approximately half of the liver's oxygen demand is met by the hepatic portal vein, and half is met by the hepatic arteries. 
Liver disease can occur through several mechanisms. A common form of liver disease is viral infection. Viral hepatitides such as Hepatitis B virus and Hepatitis C virus can be vertically transmitted during birth via contact with infected blood.   According to a 2012 NICE publication, "about 85% of hepatitis B infections in newborns become chronic".  In occult cases, Hepatitis B virus is present by HBV DNA , but testing for HBsAg is negative.  High consumption of alcohol can lead to several forms of liver disease including alcoholic hepatitis , alcoholic fatty liver disease , cirrhosis , and liver cancer .  In the earlier stages of alcoholic liver disease, fat builds up in the liver's cells due to increased creation of triglycerides and fatty acids and a decreased ability to break down fatty acids .  Progression of the disease can lead to liver inflammation from the excess fat in the liver . Scarring in the liver often occurs as the body attempts to heal and extensive scarring can lead to the development of cirrhosis in more advanced stages of the disease.  Approximately 3–10% of individuals with cirrhosis develop a form of liver cancer known as hepatocellular carcinoma . 
Patients with Diffuse Liver Hemangioma likely have severe hypothyroidism which is caused bye type 3 Iodothyronine deiodinase, this enzyme cleaves off iodine and inactivates it the body. Aggressive Thyroid Replacement therapy may balance this mechanism. Monitoring TSH levels can help determine the dosage of thyroid replacement medication to use. Once the liver Hemangioma has involuted thyroid replacement therapy can be discontinued. Traditionally the management of this type of liver hemangioma did not include Aggressive Thyroid Replacement Therapy, the hemangioma was managed but the child was impaired mentally due to hypothyroidism. Understanding the management of TSH levels has prevented this complication.
