Exoboline is marketed in Germany as a non-steroidal anabolic drug. Exoboline is not available in the US commercially or "otherwise". Exoboline is a co-enzyme of vitamin B12. This participates in protein synthesis and is water based injectable, so we assume that Exoboline is quite fast acting and relatively short lived in the body, and probably has zero side effects? Exoboline should get in the states one way or the other.
