This is the concentrated presentation - 200 mg of methenolone enanthate per millilitre, twice the strength of the usual 100 mg/ml preparations, in a sealed 10 ml vial. The practical effect is a smaller injection volume for the same quantity of drug, which counts for something with an oil that is otherwise drawn in fairly large amounts.
Concentrated oils generally need more solvent to keep the steroid dissolved, and that can make them sharper going in than a dilute preparation. Dragon Pharma produces the standard-strength ampoule version of the same compound alongside this one.
