Like the old 1-AD, that was androstenedione and androstenidiol, that convertes to 1-testosterone (di-hidroboldenone), the old 19-nordIOL used to converte at a ridiculous rate, about 0,5% (considering biodisponibility and conversion) to deca, and the 19-norDIONE to dienolone! Because both 1-ad and "deca" 19nor PH was banned, some labs are trying to put a new substance, like the 1-t and the new 1-ad, that in the best option is 1-dhea (if it is possible), called 1-androsterone! So far I know, androsterone is a "inactive" sub-product of testo and dht, the one tha is eliminated from our body, and that has no chance to be "re-converted" to testo, but...
well, this new decavol is something like the new 1-ad, called 19norandROTESRONE! let's say, something 19-nor-dhea (!!??). View, like new 1-AD, the crosslink between "3b-ol, 17-one" (like the real hormone), different form the originals: 3b, 17 diol or 3b, 17-dione!!!!
