by Bill Roberts - Primobolan
Depot is a Class I steroid working well at the androgen
receptor but which apparently is ineffective in
non-AR-mediated anabolic effects. It is most closely
compared to Deca Durabolin,
requiring a little higher dosage to achieve the
same anabolic effect, but since it is pleasant to
use at doses considerably higher than what is pleasant
for nandrolone esters, it can achieve higher maximal
effectiveness. That is, provided that one can afford
it a gram per week of Primobolan Depot can be costly.
400 mg/week should be considered a reasonable minimum
dose.
It appears to cause less inhibition
than Deca or testosterone
for any given degree of anabolic effect, perhaps
because of low CNS activity, lack of conversion
to DHT, and lack of aromatization to estrogen. Unlike
Deca, it is not metabolically deactivated by 5a-reductase
and therefore is not as kind to the skin and hair
as that drug. However, when used by itself
at modest doses, by suppressing natural testosterone
and DHT production, it can improve skin relative
to using no anabolic steroids at all.
The half-life is probably about
5 days.
The drug is particularly excellent
for use as the last injectable used in a cycle,
since for any given anabolic effect it gives much
less inhibition than other steroids such as testosterone,
nandrolone, or trenbolone.
Therefore, residual levels of Primobolan can allow
recovery in the taper while still offering useful
anti-catabolic or even anabolic support.
Methenolone enanthate is the chemical
name of active ingredient in Primobolan.
Primobolan was a registered trademark of Schering
AG in the United States and/or other countries prior
to cancellation.
