19-nor androstenedione (also known as nor andro,
19 nor andro, and/or 19-nor) is a chemical molecule
that's virtually identical to androstenedione
(itself a metabolite of DHEA) with the significant
exception that unlike androstenedione, 19 nor
andro lacks a carbon molecule in the 19th position
(hence the "19-nor" prefix).
Because of this, 19-nor androstenedione is
actually converted to what's known as nor-testosterone
in the liver (while androstenedione is converted
to testosterone).
Basically the thing to remember is that nor-andro
converts to nor-testosterone.
While not quite as anabolic as testosterone,
nor- testosterone-often called nandrolone-is
still a potent anabolic molecule in the body.
19 NorAndrostenedione - Nandrolone
Nandrolone is chemically the foundation of
Deca-Durabolin. "Deca" has of course
been one of the most popular anabolic steroids
in the bodybuilding world for years largely
because of its muscle growth properties and
its relative lack of serious side-effects.
Nandrolone is quick to attach itself to natural
steroid receptors in the body. And it's further
believed that nandrolone's effects last longer
than even testosterone. The real benefit of
nandrolone, however, may be that while it produces
good anabolic effects in the body, its aromatization
to estrogen and its negative androgenic side-effects
are significantly lower than that of testosterone
and testosterone precursors like androstenedione
and androstenediol.
So with 19 norandrostenedione, the chances
of estrogen induced side-effects such as gynecomastia
(female-like breast tissue) and DHT complications
such as acne, male pattern baldness, and enlarged
prostrate are greatly reduced.
This combination of anabolic properties with
reduced estrogen aromitization and androgenic
complications is precisely what makes 19-norandro
such an effective,
potent, and relatively safe muscle-building
supplement. One important side-note here is
that tested athletes need to be aware that because
of its conversion in the liver to nandrolone,
19-norandrostenedione may indeed lead to positive
on a steroid test for Deca or Nandrolone.
19 Nor Andro Recommendations
Recommendations: For best
results take 100mg-250mg of 19 nor androstenedione
1-3 times daily. On training days, be sure to
take one dose approximately 30 minutes prior
to training.
Cycle: You need to cycle 19-norandrostendione
so that your body doesn't simply adjust to the
high levels of nandrolone. Cycle on for 4-6
weeks maximum; then cycle OFF for at least 2-4
weeks before repeating. Longer time off is even
better.
Women: 19-nor androstenedione
is one of the few prohormones that women can
benefit from without significant side effects.
Women should use the lowest effective dosage
levels possible. Most of my female clients report
that doses of 100mg per day or less are sufficient
to produce desired results; many start with
50mg on training days and monitor results closely.
Brand Recommendations: There are several
quality 19- norandrostenedione products on the market. The
highest dose product is AST's popular 19-Nor 250.
