by Bill Roberts - This oral anabolic-androgenic
steroid was synthesized and approved under the brand
name Nilevar as the first orally-active AAS in 1956.
Norethandrolone has moderate progestagenic activity.
I don't have information on whether
Winstrol counteracts
this, as appears to be the case with
Anadrol®, but in any case
it is not considered a particularly useful drug
for male bodybuilders. For female bodybuilders,
it is probably an average synthetic, comparable
to Dianabol. It shares
the liver toxicity issues common to 17-alkylated
steroids.
It probably has low conversion to
estrogen (contrary to claims made elsewhere).
Norethandrolone is the
chemical name of active ingredient in Nilevar.
Nilevar was originally a registered trademark
of Searle Laboratories in the United States and/or
other countries prior to cancellation.
