SP Primobol for intramuscular injection, contains Methenolone Enanthate.

Methenolone Enanthate is a DHT based anabolic steroid. Known under the brand name of SP Primobol® in tablet or injectable form.

When SP Primobol interacts with the aromatase enzyme it does not form any estrogens. SP Primobol is used by people who are very succeptible to estrogenic side effects, having lower estrogenic properties. Methenolone is available as an injectable steroid or as an oral (Primoxyl). The injection is naturally regarded as having a higher bioavailability. Its 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. This reduces the stress on the liver, but also the availability. SP Primobol is considered one of the safer steroids, meaning it has a very little side effects. Methenolone has no estrogenic side effects, and its effects on cholesterol levels are minimal. In doses of 200 mg of SP Primobol 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 tolerance) will vary.

SP Primobol 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.

Each SP Primobol 10ml Vial contains:100 mg/ml Methenolone Enanthate.
