Stanodrol is the name for the cel ph to dht.
It contained *epi-androsterone, which is the beta isomer and *weaker of the 2 step pro hormones to dht.
androsterone is the alpha isomer and more expensive stronger version of the 2-step pro hormones to dht.
Back in the day, androsterone was all the rage, but fda crack downs probably led to people using epi-andro ( pa had tested a number of so called “androsterone” containing products to find they actually contained the weaker/cheaper B-isomer
, so I’m sure this was noted by the fda)
