Other possible side effects may include headaches, nausea, vomiting, stomach aches, lack of appetite, insomnia, and diarrhea. The athlete can expect a feeling of "general indisposition" with the intake of Anapolon Anadrol 50 which is completely in contrast to Danabol 10 which conveys a "sense of well-being". This often creates a paradoxical situation since the athlete continues to become stronger and bulkier while, at the same time, he does not feel well. The increased aggressiveness is caused by the resulting high level of androgen and occurs mostly when large quantities of testosterone are "shot" simultaneously with the Anadrol 50 . Anadrol is not a steroid for older athletes since they react more sensitively to possible side effects, and the risk of liver damage and prostate cancer increases. Since the drug is usually taken with a diet rich in calories and fat needed to build up mass, the cholesterol level and the LDL values might increase while the HDL values decrease. The body's own production of testosterone is considerably reduced since Anadrol 50 has an inhibiting effect on the hypothalamus, which in turn completely reduces or stops the release of GnRH (gonadotropin releasing hormone). For this reason the intake of testosterone-stimulating compounds such as Pregnyl HCG and Clomed is absolutely necessary to maintain the hormone production in the testes.
