BI-CLEN is not a steroid and does not work by increasing testosterone. In fact, the main use of BI-CLEN is not to trigger hypertrophy. Instead, BI-CLEN principle use is to increase energy levels and burn fat, thereby helping to create more of a ripped, lean and toned physique.

BI-CLEN increases the volume of oxygen circulating around the body. In that regard, it is similar to EPA, which is the PED of choice for cyclists and long-distance runners.
