In higher doses is it used for doping, but in low doses, 100mg/week up to 300mg/week it's good for HRT.
It has the power of Testo, but only anabol (good for health and power) but has nearly none on androgen side.
Instead of DHT is it converted to DHN and this is even less androgen then Nandrolone itself.
=> you are fit but your genitals are useless with it (search on google about "Deca Dick"!).
After you have used it you will have a longer time to recover your T production. This will need months up to a year.
So you not need Androcur after using it for long time or have to supplement T if you need it.
