Stanozolol - Reference Information
| pharmacological action | kanglilong is anabolic hormone. Its protein assimilation effect is strong, 30 times that of methyltestosterone, while androgen activity is only 1/4 of the latter. This product has the effects of promoting protein synthesis, inhibiting protein heterogenesis, reducing serum cholesterol and triglycerides, promoting calcium and phosphorus deposition and reducing bone marrow suppression. It can also increase physical strength, appetite and weight gain. |
| Indications | Canolone is clinically used for severe illness and postoperative frail emaciation, the elderly and infirm, as well as various chronic wasting diseases, osteoporosis, pediatric dysplasia, aplastic anemia, leukopenia, thrombocytopenia, hyperlipidemia, etc. |
| adverse reactions | lower limbs and facial edema may occur at the initial stage of taking medicine. Long-term application may lead to jaundice and liver function damage, which may lead to liver cancer. Some have delayed menstruation and female masculinization. |
| use | for chronic wasting diseases, serious diseases and postoperative infirmity, old age and infirmity, osteoporosis, dysplasia in children, aplastic anemia, etc. Prevention and treatment of hereditary angioedema |
