Ultima Pharmaceuticals labels this 10 ml vial as Primo 200, holding Methenolone Enanthate at 200 mg per ml. The enanthate ester distinguishes this from acetate versions of the same substance, which are typically sold as tablets or shorter-ester injectables. One vial supplies the full 10 ml at the stated concentration, and the glass vial format matches what most injectable anabolic steroids use across labs. Ultima Pharmaceuticals has been based in the USA and has produced this line since 2022.

Methenolone Enanthate 200 mg Concentration

The 200 mg per ml strength sits between lower-dosed primobolan options and the occasional 250 mg offering. Xeno Labs lists a primobolan 100mg/ml vial at half this concentration, meaning twice the volume is required to match the same milligram total. The enanthate ester lengthens the release profile compared to acetate, which is why enanthate versions are almost always injectable while acetate appears more often in oral form. This vial holds 2,000 mg total across its 10 ml volume.

Primobolan 200 Vial Beside Other Injectable Lines

The 10 ml vial format is standard across Ultima Pharmaceuticals' injectable range, shared with their Deca 250 and Bold 250 products. Other labs stock the same substance at different concentrations: where this vial reads 200 mg/ml, a 100 mg/ml version requires double the injection volume per dose, and a hypothetical 250 mg/ml concentrate would reduce it. The primobolan for sale category includes both enanthate and acetate ester products, and the two are not interchangeable in labeling or in typical pack presentation. This enanthate solution is ready for intramuscular injection as supplied, with no reconstitution step required.
