Most of the 'prohormones' that have been sold since about 2002 are not actually prohormones at all, but rather they are designer steroids. When the DEA listed androstenedione, 19nor-dione, etc, They encompassed MOST precursor molecules(prohormones). However, they didn't name every possible steroid(which are active in and of theirself... they don't need to be metabolized in order to have an anabolic effect... thus, they are steroids, not prohormones), so supplement companies basically went through old medical journals, lists of anabolic steroid molecules that had not been used medically(or studied for use... ), so the compounds weren't 'listed' as an anabolic steroid under the DEA schedule narcotics list... So, they called them 'prohormones' and sold them.
Examples of these compounds are:
M1T
SUPERDROL
MENT
FORMESTANE(STEROIDAL ANTI-E)
METHYLSTEN
ETC...
These are all designer steroids, not prohormones(because they are active anabolic compounds, not precursors). Many of them are HIGHLY effective, and most of them tend to be rather toxic... Hence the reason they were not patented and used medically in the past when the structure was originally 'discovered', because there were others that would serve the medical purposes desired without the level of toxicity, other side effects. BUT, they weren't typically looking for mass builders or performance enhancement(they were looking for aas that could be used for anemia, etc...), so some of the ones we know are EXCELLENT mass builders(superdrol, m1t) were just 'left in the books' til the last 10yrs or so...
