Characteristics

Furazabol THP is the same compound as the illegal anabolic steroid furazabol except it is not 17aa methylated, and instead has a THP ether attached on the 17b position. 

Furazabol does not aromatize and also has very minimal bloat. It has a moderately potent androgenic activity, giving it a fairly low risk for gyno or negative effects on the libido. However its androgenic effects may pose a problem for users prone to androgenic related hair loss.

Once the Furazabol THP reaches the stomach, most of the THP-ether is removed by the stomach acid to form the active Furazabol (the non-methylated version). Therefore, topical delivery of this compound is probably not worthwhile.  Furazabol has a similar structure to the illegal anabolic steroid stanozolol (Winstrol).  The only difference is the pyrazole ring has been replaced with a furazan ring.  There is rumor that this compound has benefits for cholesterol levels.  While some evidence proves that it can lower total cholesterol, it should be noted that the decrease in cholesterol is mostly due to a decrease in HDL. Therefore, your LDL/HDL ratio would become worse. 

Overall this compound produces mild gains, but the side-effects are very mild too. Noticeable gains in lean muscle mass and strength are likely not going to be achieved unless doses of at least 200mg/day are used. Furazabol is going to produce very little water retention, therefore it should produce a lean and vascular appearance. Big increases in weight are not likely to happen with this steroid either, so increased blood pressure and painful back pumps should not be a problem.

The half-life of this compound is short, so dosages should be taken every few hours to keep blood levels stable. Although furazabol can successfully be used as a standalone it can be stacked with other compounds depending on the users goals.
