PRIMO 100 10ml 100mg (Gen Pharma) is a DHT based anabolic steroid.
When it interacts with the aromatase enzyme it does not form
any estrogens. It is used by people who are very susceptible to estrogenic side
effects, having lower estrogenic properties than Nandrolone. Methenolone is
available as an injection or as an oral(Primogen). The injection is naturally
regarded as having a higher bioavailability. Itās an enanthate ester which is
quite long acting. Because it by-passes hepatic breakdown on the first pass, it
also has a higher survival rate. The tablets are in a short-lived acetate form.
Methenolone is not 17-alpha-alkylated, but 1-methylated for oral
bioavailability. This reduces the stress on the liver, but also the
availability. It is considered one of the safer steroids, meaning it has a very
little side effect. Methenolone has no estrogenic side effects, and its effects
on cholesterol levels are minimal. In doses of 200 mg or less (intramuscular)
blood pressure is rarely altered.
Possibly one of the safer anabolic steroids
for females due to very low virilization effects in short-term usage. Of course,
this is not a blanket-statement and individual results (dependent on doses and
tolereance) will vary.
Methenolone is also not overly suppressive of the HPTA
axis, although how suppressive is debatable. For this reason, many bodybuilders
use it in between steroid cycles during their "off-time" to help maintain their
gains and strength. The long term safety of such a practice possibly dangerous
and can lead to permanent suppression of the HPTA.
Arnold Schwarzenegger is
rumored to have introduced methenolone to the US bodybuilding community.
