Stanozolol 10mg 100 Tablets STANZTAB 10 is an oral androgen, a derivative of Dihydrotestosterone (DHT). Stanozolol was originally developed to treat hereditary angioedema. As with most Androgens Stanozolol will help to create a state of anabolism and contribute to a significant increase in muscle tissue. Structurally, stanozolol is not capable of converting into estrogen therefore will not contribute to water retention which may be the case with other androgens. Also unlike most anabolic steroids, is not esterified. The drug has a large oral bioavailability, due to a C17 α-alkylation which allows the hormone to survive first pass liver metabolism when ingested.
