The prescribing guidelines for Primobolan Depot recommend a maximum dosage of 200 mg at the onset of therapy, and a continuing dosage of 100 mg every week. Prolonged administration protocols generally call for a 100 mg dosage every 1-2 weeks, or 200 mg every 2-3 weeks. The usual administration protocols among male athletes call for a 200-400 mg per week dosage, which is taken for 6 to 12 weeks, which is sufficient to promote very noticeable increases in lean muscle tissue. It is, however, not unusual to see the drug taken in doses as high as 600 mg per week or more, although such amounts are likely to highlight a more androgenic side of methenolone, as well as exacerbate its negative effects on serum lipids.
